real turn wedges

This is Central City Mobility Project update #16.

A post today on Streetsblog LA (Santa Monica’s New 17th Street Curb-Protected Bike Lanes are Amazing) is about new bicycle facilities on 17th Street in Santa Monica. I think you will find some of the photos interesting. At first glance, it looks like some of the ones being installed as part of the Central City Mobility Project, but looking more closely, two differences really stand out. Most of the separated bikeways in Santa Monica are curb-protected. Bikeways that are solely parking protected only are protected when cars are parked. Otherwise, they are really just buffered bike lanes. And the turn wedges are hard curbs with additional markers, not paint-only, and definitely superior to the Sacramento’s suggested turn wedges which might have vertical delineators or other markers, but won’t have curbs.

To illustrate the problem these curb turn wedges solve, see the photo below of a motor vehicle making a high speed dangerous turn over a painted parking wedge at P Street and 15th Street.

  • P Street markings including green paint are nearly complete. In two blocks, the green paint is nearly the entire block, for unknown reasons. There is nothing unique about these blocks. While green paint is useful to mark conflict areas, excessive use will just lead to maintenance expense over time.
  • Q Street has preliminary markings, but the temporary lane tabs still indicate overly wide and dangerous general purpose lanes.
  • 19th Street is nearly complete from H Street to Q Street, but there is no marking south of Q Street. South of Q Street, the old bike lanes show in some places, but otherwise have been erased in favor of overly wide and dangerous general purpose lanes. Several blocks of the new bikeway are in the gutter pan, making an unacceptable rough and dangerous surface.
  • 21st Street is complete except for a few spots that were missed and have not been picked up. The confusing arrow at 21st Street and W Street has been corrected. There is still accommodation or signal for bicyclists at 21st Street and I Street.
  • I Street work has begun, with the last few ADA ramps complete and some repaving.
  • 10th Street has the last few ADA ramps complete.
  • 9th Street doesn’t have any work in evidence.
  • 5th Street has not progresses past installation of signal bases.
  • Overall, no vertical delineators have been installed at any locations.
  • Delivery vehicles are parking in and blocking the separated bikeway on P Street approaching 16th Street. The city did not mark any of the parking spaces for delivery use. Cones and barricades have been placed in the buffer to reduce this hazardous driver behavior, and have been removed by someone, and replaced by citizens, and removed by someone, and …

turn wedges of death

This is Central City Mobility Project update #15.

I have been following the progress of the Central City Mobility Project which has now mostly completed separated bikeways on 21st Street, half of 19th Street (H to Q), most of P Street, and now going to Q Street. One of the features of the design is ‘turn wedges’ which I have written about before: where the bike lane ends – update, where the bike lane ends, Central City Mobility update. I have spent a lot of time observing driver and bicyclist behavior at the intersections which have these turn wedges installed. The wedges are marked only by white paint, though city diagrams show them having some sort of physical barrier installed in them.

Drivers are using the turn wedges, and the buffer areas of the separated bikeway, to make very high speed, very wide turns at these corners, cutting the corner where a bicyclist might be riding. The prior configuration of a regular intersection did not allow such wide and high speed turns. I have seen a number of close calls between motor vehicles and bicyclists, and walkers, for that matter, since these high speed turns cross the crosswalk as well as the bikeway. These turn wedge corners are also encouraging drivers to run red lights, even more so than the usual red light running. I saw three drivers run the red on a single signal cycle, and a driver on the cross street had to slam on their brakes to avoid a collision. I’ve seen a large number of near-misses for motor vehicles.

It is not clear whether these turn wedges are complete or not. Will the city actually install something here that prevents or at least discourages these high speed dangerous turns? I don’t know. What I do know is that in the meanwhile, these turn wedges are a clear and present danger to bicyclists.

I spent time this afternoon watching left turns from P Street westbound to 15th Street southbound. Drivers were using the buffer area and the bikeway to form two lines of left turning traffic, where there should be only one. The block of P Street was completely devoid of parked cars, so drivers were queuing into two lines way back near 16th Street. Since the intersection is in no way marked for a double left turn lane, there were motor vehicle conflicts on every signal cycle.

Sorry to be the doom-sayer, but I have to recommend that bicyclists simply not ride on these streets until the projects are truly complete, with as full a protection for bicyclist as can be achieved with these less than international best practice designs.

The city’s attitude seems to be that since the bikeways will eventually be safer, we just have to put up with the unsafe situation in the meanwhile. I completely disagree. This may be criminal behavior on the part of the city, to remove moderately safe bike lanes and replace them with unsafe bikeways. If bicyclists (or walkers or drivers) die before the project is complete, is this just a ‘whoopsie’? Professional engineers designed this project, signed off on this project, and should be inspecting the project as it goes along. Why do we then have these unsafe situations? Is is intentional? Is it indifference to bicyclists and walkers? Is it professional incompetence?

It is imperative that all construction projects accommodate walkers and bicyclists, who are even more vulnerable at these projects than normally. The attitude of ‘it will be safer later’ is completely unacceptable.

The construction company for this project is McGuire and Hester. Though many people might blame these problems on the construction company, I don’t. It is the city’s responsibility to design safe projects, during and after construction, and it is the city’s responsibility to inspect projects to see if they are complying with the design, and to fix things if not. But I strongly suspect that the construction company is doing exactly what the city told it to do.

bicycling at 21st St & I St

This is Central City Mobility Project update #14.

When bicyclists using the separated bikeway on 21st Street come to I Street, they are left without any bicyclist facilities at all, in a hazardous situation. The city intends to install a bikes-only signal here to allow bicyclists to proceed when motor vehicle traffic is not moving, but until at least late July, bicyclists are on their own. See the previous posts where the bike lane ends – update and where the bike lane ends for background.

The city has recommended, in the information sign on 21st St approaching I St, that bicyclists cross I Street using the pedestrian signal. I recommend otherwise. The double left turn general purpose (motor vehicle) lanes from 21st Street northbound to I Street westbound encourage drivers to make high speed turns, with no attention to other roadway users, while the pedestrian signal shows the white walker. This was a serious problem before the reconfiguration of 21st Street, but now is worse because not only are walkers are endangered, but now bicyclists as well.

I recommend looking for gaps in traffic from 21st Street southbound (21st is two-way north of I Street with much less traffic and much lower speeds) and I Street westbound (I Street to the east is a two-way street with much less traffic and much lower speeds), and cross against the red light. Illegal, yes. But safer to be making an illegal move than competing with drivers turning left on the green light.

This intersection could be made safer in the meanwhile by two city actions: 1) Create a separate phase for walkers crossing I Street on the west leg, where the signal remains red; and 2) Prohibit left turns on red at the signal. Since this is a one-way street to one-way street turn, it is legal to turn on red, unless posted otherwise. The advantage to prohibiting left turn on red is that it will allow bicyclists to only pay attention to two opposing traffic movements rather than three. It will be necessary to prohibit left turns on red when the bike signals are installed, so why not do that now? There is a ‘left turn yield to pedestrians’ sign here, but it is small and mounted high up, so unlikely seen by drivers. Drivers may reasonably expect walkers crossing at slow speed, but are not expecting bicyclists crossing at much higher speed. It’s why bicyclists are discouraged from riding crosswalks, and why the city is wrong to be encouraging such behavior here.

Central City Mobility update #13

21st St: Nearly all striping is done and green paint complete, except for a few spots that were missed. No vertical delineators have been installed. No bicycle signal has been installed at 21st St and I St, and according to a SacBee article (Sacramento to install new bike signal at midtown cross street. How it will change traffic?), will not be installed before late July. The turn wedges are a continuing hazard to bicyclists as they imply that drivers will make safer turns, but they are not doing so.

19th St: Most striping and green paint has been installed from H St to Q St, with a few spots still being worked on. No striping has been installed south of Q St to X St, there are still temporary lane marking tabs without bike lanes. No vertical delineators have been installed.

P St: Repaving from 21st St to 15th St is complete, and white line striping is nearly complete. No green paint yet, no vertical delineators. P St has several of the unsafe turn wedges. In the blocks from 17th St to 15th St, drivers are parking in the bike lane, but to the east, drivers seem to be using the detached parking correctly.

Q St: It has been stripped down, and paving should occur soon.

10th St: ADA ramps nearly complete, but no sign of reconfiguration.

9th St: No work. It is unlikely that 9th St will be completed this year (or next?), as there are three blocks of major construction that block sidewalks and bike lanes, and would prevent completion of any roadway reconfiguration.

5th St: No further work beyond the signal bases that were installed some while ago.

I St: No parking signs have been up for quite some while, but there is no evidence of work beyond a few ADA ramps.

Central City Mobility update #12

I really am not sure if this is #12 on Central City Mobility Project, but close, so I’ll go with it.

Nothing has changed on 21st Street since the last post.

On 19th Street, some of the striping has been completed as far south at P Street. This is only white, long-line striping, none of the details have been painted. While riding 19th Street today, I was very nearly hit by a driver at O Street. The long-lines lead drivers to think that they have full width right of way, and to not expect bike riders to be coming out to pass the curb extensions at O Street. As I have said all along, I question putting extensions in locations with separated bikeways. It may be less dangerous once the detailed striping and green paint are installed, but it won’t be as safe as it could be if the city had simply not installed extensions on the east side of the 19th Street and O Street intersection.

A friend pointed out that the separated bikeway on 19th Street southbound is more than half in the gutter pan, and that the gutter pan is deteriorated in many locations. Therefore the effective width of the separated bikeway is not six feet, but about two feet. Smooth sailing for drivers, not for bicyclists!

As is true of every street that has been repaved, or patched, so far, the lane tabs have indicated that the general purpose lanes are very wide, and there are no bike lanes. Bike riders are now exposed to higher speed traffic (because of the very wide lanes), with not even the slight protection of paint.
Though this might be the fault of the project contractor, I doubt it. If the city had told the contractor to keep temporary bike lanes, they would have. I’m almost certain that the city did not say anything about accommodations for bicyclists to the contractor. The city is endangering bicyclists during this construction project, on purpose and with full knowledge. If someone is hurt or killed here, it will be on the city, and I hope they get sued for millions. The city philosophy, overall, for this project and every other construction project on streets and sidewalks, is that bicyclists and walkers don’t matter.

The city has claimed that they are now, finally, working on a construction accommodation policy. I suspect that it will come out very weak, because Public Works still believes strongly in cars-first. Traffic flow and ease for drivers controls all their decisions.

P Street has been repaved, but does not have any marking yet. Q Street has been patched, though I can’t tell if there is more to be done. A reader pointed out that there is some active work on 10th Street, but I haven’t gotten there yet.

A friend mentioned that traffic was a disaster when the city closed Q Street and 15th Street, with traffic backed up for many blocks. Though I did not observe this, I’ve had reports now from many people that the detour signage for this project does not provide drivers (or bicyclists) with any information about which way to go (the detour signs, I have observed, frequently point two directions, and the signage along the detours is incomplete. This could, possibly, be the fault of the contractor, but if the city was not out inspecting the detours and getting them corrected, the city was also failing. I have talked to a number of people on the street for whom this project has left a bad taste in their mouth. They have seen that the city has done a poor job of communicating with drivers, bicyclists and walkers, and there is a lot of doubt being expressed about whether the separated bikeways will actually be safer.

Lastly, I will note that there was no public outreach on this project. There are no plans available to the public. I am sure if there had been outreach, some of the design details would be different, some of the flaws would have been caught, communication would have been continuous and effective, and construction signing would have been done correctly. This was an internal Public Works project, and it was not done well.

where the bike lane ends – update

This is Central City Mobility Project update #11.

On Wednesday afternoon, the sign below was on 21st Street approaching I Street. The sign was not there on Tuesday morning. If a bicycle signal was intended at this intersection in the design, why was it not signed earlier? Why wasn’t the signal already installed, since there was signal communications infrastructure installed at this intersection several weeks ago? Or was this a design oversight that the city decided to fix after being called out on it? And when is ‘coming soon’?

I observed bicyclist behavior at this location for a while on Tuesday. Every single bicyclist who was headed north on 21st Street crossed against the red light, so as to not be hit by left turning drivers who generally do not yield to anyone in the crosswalk, and then onto the sidewalk on the west side of the street, continuing through the area at Old Soul Weatherstone which is congested with tables and walkers. So the city has trained bicyclist to ride on the sidewalk. Those who have been so trained will be likely to continue sidewalk riding even after installation of the signal. Ouch!

Useless Turn Wedges

I have ridden 21st Street a number of times, to see how the project is progressing and to see how drivers are responding to the new layout. Most drivers are parking correctly in the parking that provides parking-protection for the bikeway, but a few continue to park against the curb. I’ve reported these to 311 for parking enforcement, but of course as always, parking enforcement reports that the vehicle is no longer there, whether it is or not.

Several times in a row drivers have turned across my path at high speed, left from 21st Street to L Street, over the green paint and the white turn wedge paint. At the times of day I was there, there were few to no parked cars, so I was clearly visible to the drivers, not in any way hidden. In both cases I had to slam on my brakes to avoid being hit by the drivers. They did not slow. The turn wedge diagram provided on the Central City Mobility Project page, shown below, clearly shows bumps and posts (vertical delineators) in the wedge. Without more detail, I can’t say whether these will actually affect driver behavior, but in general only hard curbs or real bollards (steel or concrete) actually affect driver behavior. In the meanwhile, drivers are being trained to turn across bicyclists, with impunity, and will not likely change their behavior when and if something is installed in the turn wedges.

I have been reading Fighting Traffic by Peter Norton, and in Chapter 2 he introduces the concept of the outside left turn, which worked to prevent drivers from cutting the corner on left turns, and was later enforced with ‘silent policemen’, hard structures that provided serious consequences for drivers who insisted on cutting corners. Later, when motor vehicles were given dominance on the roadway, these were removed. It is time to bring these back!

Other

Striping and green paint is very nearly complete on 21st Street. 19th Street has been repaved and preliminary marking installed (the dashed white lines). P Street was just stripped for new pavement (I’m not sure what this process is called, removing 2 to 3 inches of old pavement so that new pavement can be laid), and is being repaved today (Thursday). Q Street has been patched but not stripped. I’m not noticing any active work on I Street, 5th Street, 9th Street, or 10th Street, though I Street has had ‘no parking’ signs up for some while.

The repaving is being done to the full width of the roadway, including the parking lane. This is a waste of materials and money. The parking lane does not need to be repaved, except in a few circumstances where it has been damaged. Nor does it need to be paved to the same standards as the general purpose travel lanes, which receive far more traffic and wear and tear. But the city loves pavement, and loves to add on unnecessary work to projects, ensuring that less is left for actual improvements to the street that would help walkers and bicyclists.

where the bike lane ends

This is Central City Mobility Project update #10.

The separated bikeway (protected bike lane) and repaving is mostly complete on 21st Street in Sacramento, part of the Central City Mobility Project. Almost all the white striping and green paint is complete. No vertical delineators (soft hit posts) yet. When I rode the street a few days ago, most vehicles were parked in the correct location in the parking spaces separated from the curb. There are two blocks where the bikeway is adjacent to the travel lane, and parking adjacent to the curb, between T Street and S Street, and between N Street and Capitol Ave. There is no obvious reason for this.

The beginning of the left side separated bikeway at W Street is marked oddly, see photo below. The arrow in the green turn box would imply that one should immediately turn onto 21st Street, when it should indicate to cross 21st Street the the bikeway on the other side. The shadow shows the correct move.

The ‘turn wedges’ noted in a an update post are is far only white paint, nothing that would prevent a driver from cutting the corner across the bikeway area. In fact, I observed several drivers doing just that.

The big concern is where the separated bikeway approaches I Street. The bikeway is on the left. Travel lanes are in the middle, one left turn only and one combined left turn-through-right turn. I Street becomes one-way westbound at this point, is two-way to the east, and 21st Street is two-way. Before repaving, the left side bike lane had a left turn arrow. The right side bike lane that was there before repaving is not there now, and it isn’t clear that there is intended to be. There is no warning that the separated bikeway ends at I Street, and no bike facility for transitioning to the right side to continue north on 21st St. This would be a good location for a bicycle signal to allow bicyclists to continue through the intersection on a bicyclist-only phase.

Central City Mobility: 5th St & Hwy 50

This is Central City Mobility Project update #9.

I had earlier expressed concern and lack of information about where the 5th Street one-way to two-way conversion will be handled where 5th Street passes under Hwy 50. (Yes, I know, that this is technically not Hwy 50, but everyone thinks it is, so…)

The following diagram was provided the the city and design firm (pdf). The configuration looks workable, and it probably not any less safe than the current mess. The merging of the two on-ramps into one narrower entrance will probably help to slow traffic entering the freeway, making 5th Street a bit safer. Same with the narrowing of the off-ramp. The curb line will need to be moved in a few locations to accommodate the entire street width with bike lanes, but the curbs here are already quite deteriorated, so that work would be needed in any case. It is not clear from the diagram whether the missing sidewalks in the block between Broadway and X Street will be corrected.

Central City Mobility update #8

Note: Info on 9th Street and 10th Street added below.

For other posts on the City of Sacramento Central City Mobility Projects, see category: Central City Mobility Project. I’m not sure how interested readers are in my minor updates, but I think it is fascinating to see how the city is repurposing street right-of-way, solving problems (or not), and what is being prioritized in the overall project. I’ve not seen any signs of construction on P and Q streets, other than the ADA ramp work that has been going on for several weeks.

Turn Wedge

The project page has a diagram that I had not exactly seen anywhere before, the corner wedge, below.

I saw a location marked for a turn wedge yesterday, at 21st St and O Street, southwest corner, below. This is a little bit like a corner of a protected intersection.

5th Street Two-Way Conversion

I looked at the length of 5th Street, from Broadway to I Street. I still have no insight into what will be done under Hwy 50 where there is a one-way block that is closely tied to the freeway onramps. I have requested clarification from the city but they have not answered yet. I’ll update when I hear.

Signal bases have been installed for new signals from W Street to N Street, but not north of there. Active work was going on at N Street. At R Street, it looks like the existing pedestrian flashing light will be duplicated for the other direction. This is not a full signal, nor a user-activated signal, but always on.

Between Broadway and X Street, 5th Street is two-way, four lanes, with sharrows marked (and very faded) in the outside lane. Sharrows are no longer considered valid bikeway markings, so presumably there will be marked bike lanes here. There are three very-wide blocks for 5th Street, from N Street to L Street, and from J Street to I Street. From N to L, there are two through lanes and one or two left-turn lanes, plus parking and bike lanes. From J to I, there are two through lanes and two left-turn lanes, plus parking left and right and a bike lane on the right.

On the west side of the intersection of 5th Street and I Street, there is a crossing prohibition. I hope that the city removes this prohibition as part of the project. In most cases, freeways onramps and off-ramps being an exception, crossing prohibitions are an attempt by the transportation agency to prioritize motor vehicle volume and speed over all other considerations. They are morally wrong, and should be legally wrong.

I Street Separated Bikeway (and lane reduction)

Some work has started on the I Street separated bikeway, which will run from 21st Street to 12th Street (see the importance of I Street for why it should continue west). Most corner ramps were already ADA compliant, but the few that were not have either been upgraded or are in progress. Fabric covers have been set up over drain inlets, and temporary no parking signs line the street, so I assume repaving will occur soon. I don’t see any indication of whether the separated bikeway will be on the right side or left side of the street. I Street does not have SacRT fixed route bus service, which engenders left side bikeways, though there is some commuter bus service on the street.

The project map indicates that I Street will be “lane reduction and separated bikeway”, not parking protected separated bikeway, so this will be a different configuration than 19th Street and 21st Street.

I will be interested to see if the city will address the lack of sidewalk on the south side of I Street between 16th and 15th, where the city installed a loading dock for Memorial Auditorium in place of the former sidewalk. I strongly believe that removal of sidewalks, as was done here, are criminal (Sac permanently closes sidewalk).

19th Street Repaving

It looks at though 19th Street is not going to be completely repaved in the way 21st Street was, rather, it is getting spot repaving. I don’t know whether there will be an overlay so that the new marking are on a fresh blank canvas.

9th & 10th Street Parking Protected Separated Bikeway

The 10th street parking protected separated bikeway will be extended from Broadway to Q Street. The block of Q Street to P Street has a buffered bike lane, outboard of parking in the south half, and without parking in the north half, and since that block has recently been changed, it will likely stay that way. There is a buffered bike lane from Q Street to L Street, and then a parking protected separated bikeway of variable quality from L Street to I Street. There is no bus service on 10th Street, so the right side configuration will probably be maintained throughout.

10th Street is relatively wide under Hwy 50, so no special treatment here will be needed.

On 10th Street there are ADA ramp upgrades at several locations, and several more haven’t started yet. The street has a lower rate of ADA compliance than many central city streets. There is no indication of roadwork yet.

The 9th Street parking protected separated bikeway is being extended south from L Street to Q Street. There is no indication of any sort of work here yet. Most corners already have compliant ADA ramps. There is construction on the east side of 9th (right side southbound) between L Street and Capitol Mall, and on the west side (right side southbound) between N Street and O Street, and between P Street and Q Street. All of these construction projects will probably be going on for quite some time, and this may be the last street to be modified. SacRT Bus Route 51 runs on 9th Street south of Q Street to Broadway, which is outside this project scope, but presumably argues for keeping the left side bikeway configuration throughout.

Central City Mobility: 19th & O curb extensions

This is Central City Mobility Project update #7.

More information on the curb extensions (bulb outs) being installed on the northeast and southeast corners of the intersection of 19th Street and O Street, as part of the Central City Mobility Project. I questioned this location for curb extensions because 19th Street with have a parking protected separated bikeways on the left side (southbound) of 19th Street. (Central City Mobility update)

I received a response from the engineering firm for the project:

This is in response to your inquiry as to compatibility of the subject intersection revisions and parking protected bike lane. The design does account for the bulb outs at the intersection. Unfortunately, due to the space restrictions resulting from the bulb outs, it won’t be possible to provide parking protected all the way around the bulb outs. However, we are providing a transition of the bike lane at the intersection. Please take a look at the following striping design for the intersection. North is to the right with 19th Street running left to right. Hopefully this will give you a better feel for the plan:

Any reader of this blog will know that I love curb extensions. What confuses me is why this location would have been selected by the city over many other potential locations. Perhaps some of the reason it that the crossing at O Street has a moderately high walker count, but does not otherwise have a traffic signal or pedestrian signaling such as a RRFB. It is possible that the city thought these four corner curb extensions to be the most practical way of increasing safety for walkers and bicyclists crossing at this point.

The design of bringing the separated bikeway out adjacent to the general purpose travel lane, as a bike lane, is not ideal but not particularly unsafe. In fact some bicyclists prefer this design, because it increases the visibility of bicyclists by motor vehicle drivers, so that they are not ‘hidden’ behind parked cars. Though daylighting of the intersection approach can accomplish the same objective.

I would like to see green skip paint continuing through the intersection in the bike lane. These are often painted as discontinuous green rectangles with sharrows stenciled on top, called green-backed sharrows. The sharrows are out of favor with most bicyclists and some traffic engineers, I think this is a valid use of them. The main purpose of green paint (it has no legal meaning) is to increase driver awareness of bicycle facilities by highlighting conflict points, and this is definitely a conflict point.
