SacCity wasted signals

This is Central City Mobility Project update #29.

I have written before about excess signals in the central city: too many traffic signals?. The fact that these exist is bad enough, but as part of the 5th Street conversion project, one-way to two-way, the city is replacing unnecessary old signals with very expensive and unnecessary new signals.

At 5th Street and S Street, a new signal is being installed. S Street is a low volume street that never needed and never should have had a traffic signal. A four-way stop sign, maybe, or maybe only stop signs for S Street. A fully signalized intersection, no way. There is nothing wrong with the existing signal for northbound traffic. Of course, a new signal is needed for southbound traffic. But the city is replacing northbound. Why?

Why is the city putting in a new signal here? Because there was one here before. If this intersection were studied for whether it needed a signal, the answer would be no. A warrant is a study indicating a need for a signal, as is simply explained at http://www.apsguide.org/chapter3_mutcd.cfm (this is much easier to read than the MUTCD). The 5th Street & S Street intersection does not meet any of these criteria. So, the city is putting in a new signal because they want to, not because it is necessary.

The current cost of a fully signalized intersection is $200K to $500K. Half a mil per. Your tax money. For intersections like 5th Street and P Street, a signal probably is necessary, particularly since the P Street and Q Street traffic sewers encourage high speeds.

It is likely that the signal at T Street is similarly unnecessary, however, T Street is busier than S Street, so might be justified by traffic volume. I’d like to see the city do a new traffic warrant study on this intersection. The city always uses warrants as an excuse for something it does not want to do, but seems to ignore these for things it wants to do. A typical traffic engineering misuse of MUTCD guidance.

Central City Mobility: 5th St signals and rubber speed bumps

This is Central City Mobility Project update #28.

Rubber Speed Bumps

The rubber speed bumps have finally been installed on most of the non-concrete turn wedges. These are marked by vertical delineators, as shown below. it is odd that most of these installations have both green K-71 vertical delineators in addition. These K-71s might have been installed temporarily, while waiting for the rubber speed bumps, and be removed later, or may be permanent. In some of the locations, the white vertical delineators have already been hit and bent by errant drivers. I have not visited all of the locations where the rubber speed bumps have been installed (or not), so don’t have any more information. More info about the rubber speed bumps is available from the vendor TreeTop Products.

how do we get more red light cameras?

I live close to Fremont Park in Sacramento’s central city. I walk through the park every day I’m in town, often multiple times. That means I’m crossing through the bounding intersections of P Street & 15th Street, Q Street & 15th Street, Q Street & 16th Street, and P Street and 16th Street, multiple times a day. I also spend a lot of time at Naked Lounge on the southeast corner of Q Street and 15th Street, and some time at Karma Brew on the northwest corner of P Street and 16th Street. That gives me a front row seat to watching the behavior of drivers at these intersections. On nearly every signal cycle, I seem a driver running the red light at each of these intersections. This is not a the exception, it is the rule. By running the red light, I don’t mean entering the intersection on yellow and finishing on red, I mean entering the intersection on red. I mean drivers that are intentionally endangering themselves, other drivers, bicyclists, and walkers. Every signal cycle.

Though I’m an able-bodied and aware walker, Fremont Park is also used by a lot of homeless individuals, families using the playground, people sitting on the benches and reading, people lying on the grass and enjoying the sun (finally) and enjoying the shade (now), people participating in a number of organized recreation activities such as yoga, and of course the festivals such as Chalk It Up. This is a place that should be safe to get to for everyone. It is not currently.

I wrote about a crash at P Street and 15th Street. I’ve written multiple times about red light cameras, pandemic of red light running, red-light-running bullies, and SacCity red light cameras and crashes.

Let me state up front that I am NOT in favor of the enforcement of traffic laws by armed police officers. I have seen first-hand the way in which traffic stops are used to harass and oppress people of color and low income. I have read and seen innumerable accounts of officers murdering the people they stop on pretext. Armed law enforcement is the problem, not the solution. On the other hand, I am strongly in favor of automated enforcement. It is my theory that most serious traffic violations are by a small number of egregious drivers. Automated enforcement can ticket these drivers, which will change the behavior of some of them, but not of many of them who are high income drivers of high end vehicles. It does, however, allow law enforcement to identify repeat offenders and hold them accountable with vehicle confiscation and drivers license suspension.

I want there to be red light enforcement cameras installed on at least one of the four intersections at Fremont Park. My observations indicate that the intersection of Q Street and 15th Street is the worst. I looked on the city’s Red Light Running Program page to see if there was a mechanism for submitting requests. No. I looked at the city’s 311 app to see if there was a place to submit a request. Not really. The closest I could find was to select Streets > Traffic Investigation, and then Signals (see screenshots below). I’ll update this when I get a response (though these days most 311 reports get no response at all).

The other way of request that might be effective is to directly contact city council members.

SacCity signal management

Part of an ongoing series of posts to support better streets in the City of Sacramento during their 2023 update of Street Design Standards. New standards must be innovative, safe, and equitable, and it will take strong citizen involvement and advocacy to make them so.

  • Signal cycles will be the shortest timing consistent with ample time for walkers to cross
  • Shorter crossing distances and therefore shorter signal cycles can be created via lane reductions and curb extensions 
  • Signalized intersections will be evaluated for signal elimination and conversion to stop-controlled intersections
  • Leading pedestrian intervals (LPI) will be installed at all signalized intersections with pedestrian signals; LPIs will be a minimum of three seconds, longer in high pedestrian crossing areas
  • All pedestrian activation buttons will be removed, or will be converted to audible-only signal activation. Temporary signing will be installed when a button has been deactivated but not yet removed.

I earlier posted on too many traffic signals? in the central city, which should be eliminated in favor of stop controlled or yield controlled intersections.

SacCity red light cameras and crashes

A follow on to red-light-running bullies. I’ve created a map that shows the eleven right light camera (automated enforcement) locations under the City of Sacramento’s Red Light Running Program. The city has 907 signalized intersections. These locations are (listed alphabetically by the intersection entry in the Traffic Signals GIS layer):

  • 16th Street & W Street X
  • 21st Street  & Broadway X
  • 5th Street & I Street X
  • Alhambra Boulevard & J Street
  • Arden Way & Challenge Way X
  • Arden & Exposition Boulevard & Ethan Way X
  • El Camino Avenue & Evergreen Street X
  • Fair Oaks Boulevard & Howe Avenue X
  • Folsom Boulevard & Howe Avenue/Power Inn Road X
  • Mack Road & Center Parkway X
  • Mack Road & La Mancha Way/Valley Hi Drive X

The map (pdf) shows each location, with the red signal icon, and a heat map of the crash severity for crashes occurring at intersections. Yellow means high collision severity, with severity being a weighting of the individual types [1 – Fatal; 2 – Injury (Severe); 3 – Injury (Other Visible); 4 – Injury (Complaint of Pain)]. But it does show the pattern, and you can clearly see the intersections along arterial roadways, where most crashes occur. The crashes are not necessarily red light running crashes. There is a PCF Violation category (VIOLCAT) 12 – Traffic Signals and Signs, and another Intersection (INTERSECT_), but that would not distinguish red light running from stop sign running. It might take looking at individual incident reports, but that is beyond my capacity.

There are certainly high crash severity locations in the city that are beyond the map coverage area, and there are plenty of locations without cameras.

It would be interesting to know if these red light camera locations have a lower rate of red light running crashes that comparable intersections without cameras, but that will require quite a bit more thinking an analysis.

red-light-running bullies

If you go stand at any busy intersection in Sacramento, you will see drivers running red lights on almost every single signal cycle. Of course this problem is not unique to Sacramento, but it is where I live and walk and bicycle, and I see it every day, at every signalized intersection. I am not talking about drivers entering the intersection on the yellow light, and not making it through before it turns red. I am talking about drivers entering the intersection when the light is already red. And quite often, they accelerate into the red light, making sure they can get through.

I call this bullying behavior. It says that I (the driver) is more important than anyone else. Me (the driver) making this light is more important than anything else in the world, which translates to my (the driver’s) convenience is more important than anyone else’s life. I (the driver) know that this is dangerous behavior, but I (the driver) don’t care.

My preferred word for this is actually terrorism. Terrorism, however, implies actions by individuals against states, or more often by states against individuals (state-sponsored terrorism). This is not that. But the intent is the same, to change other people’s behavior by the threat of violence, or actual violence. This is traffic violence perpetrated by entitled drivers against everyone else on the road. Terrorism may not be technically correct, but it sure sounds right.

Most drivers have adjusted to this by not starting into the intersection on the green, but waiting until the run light running driver has cleared. Same for people bicycling and walking. Most walkers know it is not safe to enter the crosswalk until all the cars have stopped, because usually they will not stop. But not all drivers, walkers or bicyclists know, and these are the people being killed or seriously injured at intersections.

Red light running has always been a problem, but it has gotten much worse. It accelerated, I think, during the pandemic, when there was less traffic, and drivers started to gamble with running red lights. Now that the traffic is mostly back, they are still doing it. In my observation, it gets worse by the month.

Many people think that the solution to traffic violence is to change road designs so as to prevent dangerous driver behavior. I’m of course in favor of this. But in this instance, re-design does not prevent this bullying behavior.

Having near-side traffic signals, as many advanced countries do, would help a little because a driver who chose not to stop loses information about how late on the red they are and therefore is less likely to run the red light. See Near Side Signals: Thinking Outside the Pedestrian Box for more info on near side signals. But this alone would not solve the problem.

Slowing speeds would help, as the red light running driver would be a little less likely to kill the walker, bicyclist, or other driver and passengers than at higher speeds. But the red light runners are in my observation the same people who are driving well over the speed limit, adjusting their risk tolerance for to the highest possible level that won’t get them killed. Of course, these are not drivers who are much concerned about killing other people.

The City of Sacramento has a Red Light Running Program. The page says there are 11 cameras in the city. Out of 4000 plus intersections. This is not a serious response to a serious problem. It is in fact the typical city response to any transportation issue, to do the absolute minimum possible to avoid being called out for doing nothing.

I believe from extensive observation (I walk a LOT), though I have no data to prove it, that red light running is done by a fraction of drivers, and those drivers do it again and again and again. They’ve gotten away with it, so far, and will continue. At least 3/4 are drivers of expensive cars, high income, entitled people. If that is so, it would not take much to greatly reduce this behavior. Ticket them again and again and again, whether directly by law enforcement officers or by automated cameras, and their behavior would gradually change. Of course if we set ticket fines based on the value of the vehicle rather than flat rates, and impounded and/or confiscated vehicles upon repeated infractions, it would change even quicker.

Law enforcement is complicit in this red light running. I have never seen a driver stopped for running a red light. Ever. And in fact, law enforcement drivers are just as likely to run red lights as any other. Law enforcement doesn’t like automated enforcement, because it reduces the opportunity for them to do pretextual stops. It also is seen as reducing the need for officers, though since they don’t do this enforcement anyway, I can’t see how it actually reduces the need.

Many people have called on the city to install more leading pedestrian interval (LPI) lights in the city, where the pedestrian indicator turns to walk 3 seconds or more before the parallel traffic signal turns green. These of course help, but even where they already exist, the interval is now taken up by the time a walker must wait for the red light running drivers to clear the intersection before proceeding. Much less effective at promoting walking and safety than it could be.

Solutions:

  • The city could recognize that this is a serious traffic violence issue, and respond forcefully, with more enforcement and more automated cameras. The city’s Vision Zero policy obligates them to take traffic violence seriously, but they do not.
  • The CA-MUTCD could be changed to require near side traffic signals instead of far side traffic signals.
  • The state legislature and judicial council could change fines for violation of California Vehicle Code (CVC) to be based on the value of the vehicle. People often talk about basing fines on income, as some first world countries do, but income is not easily available to the law enforcement officer or processor of the red light camera mailed ticket, whereas the value of vehicles is available in the DMV database. If you run a red light in your $1000 clunker, the fine would be $1, and if you run a red light in your $200,000 trophy car, it would be $2000. To start.
  • Along with higher fines for drivers of fancy cars, the vehicles of these drivers should be impounded for the third violation of the same CVC within a year. Impound means you get the vehicle back after a certain period of time, maybe three months. And for those drivers that doesn’t control, then the vehicle should be confiscated, meaning you don’t get it back and the agency sells it. Maybe for more than six violations of the same CVC within a year, or ten within three years.
  • Walkers and bicyclists could equip themselves with paint ball guns so as to mark the vehicles of these bully drivers, so at least other people could see them coming. And perhaps other drivers would them start enforcing social pressure on them. It worked for smoking, when people who smoked in buildings and on transit were publicly shamed.
  • And of course, in the long run, we do need to re-design streets to that red light running is less likely, and less likely fatal due to lower speeds.

Sac Vision Zero intersections & red light cameras

I’ve written previously about Vision Zero high injury intersections in the City of Sacramento: Sac Vision Zero new intersections map, Sac Vision Zero top intersections all modes, Sac Vision Zero top ped intersections, Sac Vision Zero Top 5 Corridors and top intersections, and Sac Vision Zero flaws.

The City of Sacramento has red light cameras at the following locations:

  • Mack Road & La Mancha Way/Valley Hi Drive
  • El Camino Avenue & Evergreen Street
  • Howe Avenue & Fair Oaks Boulevard
  • Mack Road & Center Parkway
  • Exposition Boulevard & Ethan Way
  • Broadway & 21st Street
  • Folsom Boulevard & Howe Avenue/Power Inn Road
  • Arden Way & Challenge Way
  • 5th Street & I Street
  • 16th Street & W Street
  • Alhambra Boulevard & J Street

The top injury intersections are:

  • Stockton Blvd & Broadway
  • Stockton Blvd & Lemon Hill Ave
  • Stockton Blvd & 47th Ave & Elder Creek Rd
  • Watt Ave & Auburn Blvd
  • Del Paso Blvd & Evergreen St & Lampasas Ave
  • Julliard Dr & Kiefer Blvd & Folsom Blvd
  • Power Inn Rd & Fruitridge Rd
  • Freeport Blvd & Florin Rd
  • Center Pkwy & Cosumnes River Blvd
  • Bruceville Rd & Cosumnes River Blvd
  • Franklin Blvd & Mack Rd

Notice there is no overlap. One could optimistically say that the presence of red light cameras may be making drivers safer and reducing the crashes at these locations. But I doubt it. More likely, the city is just not prioritizing high injury intersections. Of course high injury intersections change over time, as traffic patterns change, and as the city redesigns intersections to be safer, so red light camera locations need not remain static.

I ask that the city install red light cameras at all the high injury intersections. I am not asking that the city move the existing cameras to the new locations. If someone thought a red light camera was necessary at an intersection, it probably still is, and should continue unless evidence indicates otherwise.

A lot of driver-apologists claim that red light cameras are not fair, that they are installed mostly to gain ticket revenue, and that they aren’t accurate anyway. Yes, some places have installed cameras for funding, but Sacramento is not one of them. Yes, sometimes the camera systems flag a vehicle that is not running a red light, but the photos are reviewed. Even if the city were making $1M a day on red light cameras, that would be just fine with me if it prevents one death. I value life more highly than do many drivers.

I worked in Citrus Heights for several years, which has a much higher percentage of traffic signals complemented by red light cameras. My perception is that it really did make a difference. I saw very little red light running in Citrus Heights. Other violations, sure, but not red light running.

too many traffic signals?

I just finished reading Confessions of a Recovering Engineer by Chuck Marohn of Strong Towns. I’ll have more to say about the book soon. The reading reminded me of a number of things I’ve wanted to write more about, and one of those is traffic signals. Chapter 7, Intersections and Traffic Flow.

“Traffic signals are the most mindless and wasteful thing Americans routinely install to manage traffic. Removing nearly all of them within cities would improve our transportation systems and overall quality of life.”

Chuck Marohn, Confessions of a Recovering Engineer

I have long wondered what the value of traffic signals really is. As a walker, they make me wait for the signal cycle when there is no traffic coming. As a bicyclist, they stop me at almost every location, because they are set for the speed of cars, not the speed of bicyclists. There are places that set signals to work for bicyclists, but nowhere in the Sacramento region. Of course as an enlightened walker and bicyclist, I wait only for gaps in traffic and not for the signal to change. As a driver, which I once was, they make me sit at an intersection when I could be moving, and slow overall travel time.

Most signals do not sense traffic loads and respond. They are on a cycle, no matter what. Rush hour, midnight, same cycle. Signals are timed to preference one direction of traffic over the cross-traffic. And they are often very slow cycles. In the county, many of the signals are on a 2.5 minute cycle, and even in urban areas they are on a slow 1.5-2 minute cycle. Drivers have come to accept the long wait, but for walkers and bicyclists for whom a red signal can increase overall travel time by 1-1/2 to two times, they make us crazy.

Signals do not slow the speed that drivers drive. Drivers wait at the red light, and then accelerate on the green to make up for wasted time, always going over the posted speed limit. Of course these days many drivers don’t stop for red lights at all, they go through intersections on stale reds (meaning it was red before they even entered the intersection). This has become a very common behavior over the years, and is almost routine since the pandemic.

One of the things that signals seem to do is shift unsafe driving behavior from intersections to corridors, the street parts in between signals. Instead of misbehavior at intersections, causing lower speed crashes, we get misbehavior in between, with higher speed crashes.

Everyone who walks knows that signalized intersections are not safe places to cross the street. Drivers turning right look only for opposing traffic, almost never for people in the crosswalk. When the light turns green, drivers accelerate into right hand turns, across the crosswalk and any walkers in it. For intersections that permit left turns on green lights, the threat of a left turning driver crossing the crosswalk at high speed is constant. So people who value their life tend to cross mid-block, where one only has to look for two directions of traffic instead of 12.

The Confessions book suggests several alternatives to traffic signals, including roundabouts, traffic circles, and shared space intersections.

  • Use roundabouts rather than traditional intersections. Of course in place where the size of intersections is constrained by right-of-way and adjacent buildings, a real roundabout may not be possible, but traffic circles, of which the central city already has a number, can fit. Traffic circles are not as effective as roundabouts, but can replace signals.
  • Slow traffic enough that people can cross streets without having to have signals to interrupt traffic.

I realize that many people associate signals and stop signs with safety, and often demand signals and stop signs when the streets are dangerous. So what I am going to say here will be controversial. For people who think traffic signals make things safer, please spend some time observing at both signalized intersections, and unsignalized intersections. Are the ones with signals really safer? For anyone?

One of my (not) favorite signals is at 15th Street & E Street. At this point, 15th Street is not a collector or arterial, it only becomes one-way a block earlier at D Street, and has very little traffic at this point. It does not become a higher volume street until H Street and I Street to the south. E Street is a collector, though not a very busy one. Yet the signal cycles all day long, with almost no traffic at it. A perfect location for a traffic circle. Not the point of this post, but 15th Street at this location does not need two lanes, one lane would be plenty, and the excess lane can be converted to diagonal parking and/or a bike lane. A photo of the intersection is below, showing a typical amount of traffic.

What about all the signals on 14th Street? This is a low volume, fairly low traffic speed street, at all times of day. It dead-ends at the convention center, so it is not really even a through street, yet it has five signals. There are a lot more such examples. You can add yours in the comments!

15th St & E St intersection, Sacramento

All the signals in the central city that are not at the intersection of collector and/or arterial streets should be slated for removal. If the city wishes to do so, it could do a traffic study before removal, or just go ahead with removal, but it should not be leaving these signals in place without action. There are options short of complete removal. Signals could be made into signalized pedestrian crossings, so that when people walking need to cross, they still have (some) protection of a red light. (Some protection. Again, many drivers to not stop at red lights.) Curb extensions can be installed to shorten crossing distances. Traffic diverters (modal filters) can be installed so that only bicyclists have a thru route. And of course roundabouts and traffic circles. At the intersection of two collector streets, a four-way stop might be appropriate. Each intersection is unique, but each one is also a candidate for change that makes travel safer and less frustrating no matter the mode of travel.

I’m not suggesting, at this time, the removal of signals at the intersection of collector and/or arterial streets. Someday.

The map shows these signal locations, with a red X (pdf). The intersections of collectors and/or arterial streets, not marked here, are not being challenged at this time. The purple streets are designated collectors or arterials by the city (part of the Functional Classification System).

red light cameras

The City of Sacramento has 11 red light camera locations: Red Light Running Program. Of these, some are at high-injury intersections, but most are not. These locations are cross-referenced with high injury intersections shown in the post Sac Vision Zero new intersections map.

My first thought is that the city was putting these cameras in the wrong location. But then I thought, what if the presence of red light cameras is making these locations safer and therefore dropping them out of the highest injury intersection list. I don’t have the information to answer that question, which would take analysis of crashes at the intersections, and before/after data.

What I do know is that many more red light cameras are needed to counteract the pandemic of red light running: pandemic of red light running. I spend time around the edges of Fremont Park, close to where I live, which includes the intersection of arterial streets P, Q, 15th, and 16th, and one of the things I do is watch traffic in the intersections. It has now become rare for a signal cycle for 16th St northbound at P St to not see an incidence of red light running. The other intersections are not quite as bad, but the pattern is there. And this is happening everywhere in Sacramento that I go; these are not likely to even be the worst intersections.

I believe that most of the red light running is by egregious violators, people who routinely and continuously violate traffic law for their own convenience or thrill seeking. This is true of most traffic violations, but red light running is the one most likely to result in fatality and serious injury, for people in all modes of travel. So having a more widespread set of red light cameras would serve to catch these red light violators. Of course the follow-up is necessary, to revoke the licenses and confiscate the vehicles of these repeat offenders. The longer the city looks the other way on this issue, the more people will come to see it as normal behavior, and the less safe our streets will be.

The standard response by cars-first entitled drivers is that tickets are just a money-making scheme by the government. The purpose of red light cameras is to make streets safer, and if that results in some income, so be it. I’m more than happy to have these sociopathic drivers hit in the pocketbook, and the money can be used to make our streets safer, such as by installing more red light cameras. Red light tickets, with photos, are part of the documentation needed to revoke licenses and confiscate vehicles.

13th & J intersection

I want to acknowledge Enzo of Streets Are Better for reminding me of this intersection and provoking me to write now in more detail. Two previous posts change the signal at J St and 13th St and J & 13th needs a pedestrian scramble were briefer and did not cover all the issues.

The intersection of 13th Street and J Street in downtown Sacramento is a mess for walkers and bicyclists, largely due to poor decisions that the city has made. The setting is below, with a historical view selected for no leaves on the deciduous trees. On the southeast corner is the convention center, which is under construction now, and the southeast corner is fenced off. On the southwest corner is the Sheraton Grand Hotel. On the northwest corner is a major downtown parking garage, managed by Ace Parking. On the northeast corner is another parking garage managed by Parking.com.

intersection of 13th Street & J Street, downtown Sacramento

In the days before construction on the convention center started and the Sheraton shut down due to the pandemic, this was one of the busiest pedestrian intersections in the central city. The crossing of 7th Street at K Street/DOCO Center, L Street at 11th Street and 10th Street when the legislature is in session, Capitol Mall at Tower Bridge, and a few others are up there, but this one is certainly in the top 10. The city rarely collects pedestrian data, so I do not know what the ranking or volume is.

When the convention center is completed and open, and the Sheraton opens at full scale, this will again become a very busy pedestrian intersection. So you would think that the city would design this intersection and signals to prioritize people walking, but you’d be wrong.

The crossing of J Street on the west leg of the intersection requires pushing the ped button. There are a number of pedestrian signals in the central city that do not require pushing the button, and these are called auto-recall, meaning they automatically change on a cycle. Not this one! I just observed a number of walkers crossing here, and only about 5% of them initially realized they had to push the button. When I mentioned that the signal would never change unless they pushed it, they were surprised, and not happy. When the ped head signal does come on, it has a white hand of 5 seconds, and a countdown of 9 seconds for a total of 14 seconds. There are three lanes of motor vehicle traffic here, lanes about 12 feet wide, for 36 feet. The MUTCD recommended crossing speed is 3.5 feet/second, so 36 feet should be a minimum of 10 seconds, but this assumes that people can leave the curb immediately, not true when the activation button is set well back, and there is pedestrian congestion. In that case, the crossing speed should be 3.0 feet/second. If you want to read about the contortions traffic engineers go through to make walk cycles as short as possible, read pedestrian crossing questions and answers.

The traffic signal for J Street will remain green unless there is a vehicle waiting on 13th Street or someone pushes the ped button to cross. The ped signal to cross 13th Street goes through a white hand, countdown, brief pause, and then back to the next cycle. Without a cross-traffic vehicle or button push, the traffic signal will never cycle. Ever.

crosswalk over J Street at 13th Street

An additional problem is that sometimes the signal controller will just skip the crossing J Street part of the cycle, even when the button is pushed. Since I’m mostly on my bicycle rather than on foot here, I haven’t quite pinned down the behavior. I don’t know if it depends on time of day, or traffic volume, or is just random, but I can affirm that it happens, and not infrequently. So even after the walker presses the button, they may have to wait through another full cycle before they get the walk.

On the southeast corner, the convention center construction has closed the corner and sidewalks. In this situation, there should be a barricade and warning signs on the opposite corner, so J Street south side eastbound and 13th Street east side southbound. A fully sighted person can of course see the barrier and fence across the street, but the point of ADA requirements is to communicate to everyone, not just the sighted. Below is what is looks like, followed by what it should look like. Remember, this is a city project, not a private development, but the city apparently holds itself to lower standards than it holds private developers.

closed crosswalk over 13th Street at J Street
proper barricade and signing for a closed crosswalk, O Street at 8th Street

The east leg crosswalk also suffers from traffic flow design. The walk sign for this crosswalk comes on at the same time as the southbound green signal comes on, bringing drivers into immediate conflict with walkers in the crosswalk. There is no leading pedestrian interval (LPI) to let the walkers get a head start. At this time the crosswalk is closed, but as soon as it is reopened, the conflicts will be immediate, as they have been for years.

Solutions?

  1. Immediately institute auto-recall on the crossing of J Street, and remove the buttons. These are not modern audible buttons, they are antiques.
  2. Immediately institute a leading pedestrian interval on the crossing of J Street, to increase protection from left and right turning drivers.
  3. Immediately lengthen the pedestrian phase for the crossing of J Street to a minimum of 20 seconds.
  4. When then southeast corner of the intersection is re-opened, with completion of the convention center construction, implement an exclusive pedestrian phase for this intersection, in which there is no movement by motor vehicles during the walk cycle, and walkers can cross in any direction including diagonally. If any intersection in Sacramento deserves this treatment, this is it.
  5. Traffic calm J Street to reduce speeds. The most important step is to reduce general purpose lanes to two, and create some sort of bicycle facility. I’m not sure of the best design, as the valet/unloading/loading are for Sheraton Grand may make this challenging.
  6. Get rid of any City of Sacramento Public Works employee who believes the purpose of central city streets is to favor suburban commuters (the J Street traffic) over walkers, bicyclist, and local residents.

I have made at least seven 311 reports on the signal problems at this intersection, asking that it be changed. The only change that I’ve been able to notice is that they lengthened the pedestrian phase for crossing 13th Street, and shortened it for crossing J Street. I just gave up after a while.

Bicyclists

That covers most of the pedestrian problems at this intersection. How about bicyclists? 13th Street is a major bicycle route in downtown, being the only north-south street that crosses through Capitol Park and is not an arterial street, often with heavy traffic and higher speeds. There are bike lanes on much though not all of 13th Street to the south J Street, and there are bike lanes on most blocks to the north, except the half block approaching this intersection. Here, the bike lane has been sacrificed to create a turn lane. There is a required left turn lane and an optional turn lane, but no bike lane. So at this busiest of all intersections on the route, there is no bike lane. There is a clear message here from the city: we will accommodate bicyclists only if it does not reduce motor vehicle capacity. Otherwise, tough luck.

The loop detectors on 13th Street only sometimes detect bicycles. I often see bicyclists during off-times, when there are fewer motor vehicles to trigger the cycle, proceeding through the intersection on red, when it is safe to do so (and occasionally when it is not). They have the right to do so, since by definition a signal that does not detect vehicles (devices) is a non-functional signal, but it is not the best solution.

When the pedestrian button is pushed to cross J Street on the west leg, but no southbound motor vehicles are present, the vehicle signal remains red, so doesn’t allow for undetected bicyclists. This doesn’t protect any walkers, so it makes not sense.

Solutions?

  1. Continue the bike lane on southbound 13th Street to and through (with green skip paint) the intersection with J Street, and remove the left turn lane which prevents the bike lane from continuing. That might mean lengthening the green light for motor vehicles in order to clear the queue.
  2. Install video detection on this intersection that will detect bicyclists on 13th Street so that they don’t have to wait for motor vehicle traffic to arrive and trigger the signal cycle.
  3. Change the traffic signal for southbound to go green at the same time as the pedestrian walk sign. This allows bicyclists to proceed without confusion.
