how to stop red light running

I’ve posted about the red light running epidemic: red light cameras and law enforcement; the end of red light enforcement; how do we get more red light cameras?; red light running consequences; SacCity red light cameras and crashes; Sac Vision Zero intersections & red light cameras; red light cameras; pandemic of red light running; and red-light-running bullies.

Of all the traffic violence occurring on our roadways, this is the one that concerns me the most. When one driver runs a red light and hits another driver going on the green light, the result is almost always serious injury and sometimes fatality. It is a particularly high impact crash because the driver running the red light is often accelerating into the intersection, because they have decided (consciously or not) that they are going to run the light, and want to get through as quickly as they can. T-bone crashes, which red light running crashes almost always are, are especially damaging.

The red light running epidemic started with the pandemic, in my observation, though it has always been present. I’ve seen multiple explantations of why this is, but the relative lack of cars on the road, and the resulting perception that the road belongs to the driver alone, is one common explanation. But as the pandemic has faded, red light running has not faded, it has increased month over month. If you observe any moderately busy intersection, you will see drivers run red lights on nearly every signal cycle. Other drivers, and people walking and bicycling, have responded to this lawlessness by not going on the green. People now expect someone to be running the red light, and pause until all the vehicles have stopped. Green lights and pedestrian signals were never a guarantee of safety, but now they are a guarantee of danger.

I have said before, and continue to strongly believe, that automated red light enforcement is the top solution to this behavior. I believe that most drivers would stop doing it if they were ticketed a few times. Some would not, or course, because there are drivers on the road for whom the cost of a ticket is meaningless, and their consideration of other people’s lives is nil. Such drivers will create a pattern of law breaking that can be identified and stopped by suspension of drivers license, and more importantly, confiscation of their vehicle. In my observation, most of the red light runners are driving high value cars. Tickets mean nothing, but loss of their expensive car will get their attention.

Red light running is the traffic violence issue probably least amendable to infrastructure solutions. It is a choice by drivers, and one not primarily induced by poorly designed roadways.

There are research papers from the 1990s through early 2010s that suggest changes to the signals to reduce red light running. Bigger and brighter signals. larger brighter reflective backplates around the signals (these have been common recently with the yellow reflective backplates). Changing the all-red interval to a longer period, or the yellow signal to a longer period, but drivers adjust to this and increase their risk behavior to compensate. Placing advance warning signing or flashing lights, more appropriate for rural situations than cities. I don’t believe that any of these have a significant impact. Horizontal rather than vertical placement of the signal heads may have some beneficial effect.

Moving signals to near-side locations of the intersection is the solution in many parts of the world. Near-side signal placing does reduce red light running because the driver is responding to the signal on the close side of the intersection, not the far side. Research supports this, but the US refuses to make this change.

And of course education, encouraging drivers to follow the law and to cease actions that endanger others. I’m pretty cynical about education. Education works when someone does not know the consequences of their behavior. But drivers do know the consequences of their red light running. They’ve gotten away with it so far, but I doubt that any of them think they will get away with it forever.

Redesigning roadways and intersections to create more friction, such as narrower lanes and curb extensions to slow drivers, reducing the energy of crashes, but neither prevent red light running. Protected intersections reduce the hazard for bicyclists and walkers, by better separating movements and shortening crossing distances, but they don’t prevent red light running.

Though research clearly supports daylighting for increasing visibility between drivers and walkers, it may also increase red light running because drivers do, or think they do, have a better view of the intersection and whether approaching vehicles are going to cause them problems. I’m all for daylighting, but this issue must be acknowledged.

I believe automated red light running enforcement is the most effective solution, but others should be considered in addition to, not in place of, automated enforcement.

I searched for but did not find any research or even preliminary information on red light running and solutions since the beginning of the pandemic. It is possible some is underway. It is not the sort of thing that would be funded in the current administration, but it might not be rescinded.

red light cameras and law enforcement

Earlier posts on red light running and automated enforcement are available at category: automated enforcement.

The City of Sacramento has a crisis in biased law enforcement against people of color and low income, and also has a crisis of red light running.

The city had red light cameras at eleven locations, part of a program managed by Sacramento County Sheriff’s Office. The county dropped the program in early 2024, and all cameras were removed. The county claimed that the fines from red light running were not paying the cost of the program, and of the contractor. The City of Sacramento therefore dropped its program and has made no effort to restart it. At the dollar value of human life being $10M or more, it is hard to understand how the county saw this program as too costly. City of Sacramento paid $27M in traffic crash lawsuits over five years. The county information does not seem to be available, but it would likely be larger due to higher population, more road miles, and more poorly designed roadways and intersections.

The nature of red light running is that a motor vehicle driver T-bones someone, impacting other motor vehicles, walkers and bicyclists at a perpendicular angle at high speeds, frequently resulting in a fatality. This is not the leading cause of fatalities, but it is significant.

There are reasonable objections to any law enforcement of traffic laws. Traffic stops are often pre-textual, intended to discover illegal activity or warrants that have nothing to do with traffic law, and to oppress people of color and low income. Law enforcement officers not infrequently escalate interactions, resulting in intimidation, unlawful arrest, and death. Law enforcement often focuses on communities with people of color and low income, both because of the pre-textual nature of stops and intended intimidation of people in those communities. Even when justified, tickets for traffic violations have an outsized impact on lower income people because fines are a flat amount no matter the income of the violator, so are strongly regressive. Court fees add a great deal to the cost of a ticket, often sending low-income people in a downward economic and legal spiral. 

Automated enforcement of traffic law removes some of these concerns, but not others. By removing the interaction with officers, law enforcement intimidation and violence is eliminated. But the issue of outsized economic impact remains.

If a red light camera program were to be restarted in the City of Sacramento, it would have to have these characteristics:

  1. The program would be operated by Public Works as part of their transportation management responsibilities, not by the Police Department.
  2. Camera locations would be selected based on traffic crash location hot-spots, but adjusted so that low-income communities do not have a higher number of cameras per-capita than other areas 
  3. For camera locations with a history of traffic crashes resulting in fatalities and severe injuries, and with a higher than average number of citations issued, the city would commit to making changes to that intersection to reduce the incidence of red light running and crashes.
  4. The fines for red light running would be reduced for low-income people. The reduction could be a) across the board for income levels below a certain set percentage of the median household income, or b) based on the value of the vehicle driven by the violator. Alternatives to fines could also be implemented. Though income based fines are often mentioned, and are used in other countries, concerns about privacy and availability of the data make this impractical. The value of a vehicle is easily available, and does track to some degree with the income of the owner. It is not certain whether these options could be implemented by the city now, or if changes in state law would be required, but the city should commit to exploring options and committing to a solution.

Two other types of automated law enforcement have been discussed. Automated speed cameras are legal under a pilot program for several cities, but Sacramento is not one of them. It is unlikely that other cities would be added, or statewide implementation would occur before the pilot is completed. It is possible that active intelligent speed assistance will become law in California, and obviate the need for automated speed enforcement, at least in urban areas.

Automated enforcement of ‘failure to yield’ to walkers (pedestrians) law would be very useful. Failure to yield sometimes results in fatalities and severe injuries, but it always results in intimidation of people walking by people driving, reducing the frequency and comfort of walking trips. The technology for detection of ‘failure to yield’ is not well developed, but has been implemented in some cities and is practical. ‘Failure to yield’ is another crisis on our roadways.

This recommendation to restart the red light camera program in the city does not indicate that it is the primary solution to the traffic violence crisis. It is one among many tools. Changes to the roadway, temporary (quick-build) or permanent, are by far the most effective solution and should be the lead action by the city.

the end of red light enforcement

A SacBee article today notes the end of the red light camera program in City of Sacramento, which was part of Sacramento County’s program: Sacramento’s red light camera program has been shut down by the Sheriff’s Office. Here’s why. (sorry about the firewall)

This is very sad news, given the epidemic of red light running in the City of Sacramento (and elsewhere). I’ve written about this before: how do we get more red light cameras?, red light running consequences, SacCity red light cameras and crashes, Sac Vision Zero intersections & red light cameras, red-light-running bullies, and pandemic of red light running. It has only gotten worse over time, and will continue to get worse unless the city takes action to reduce it.

A quote from the Sacramento County Sheriff’s Office is particularly galling: “Gandhi said the Sheriff’s Office wants to focus on its mission of suppressing violent crime and other criminal activity.” Apparently, in the view of law enforcement, traffic violence is not a violent crime. Apparently, the fact that red-light runners kill and injure walkers, bicyclists, passengers, and other drivers is of little concern. Sadly, this is a very common law enforcement attitude.

If cost-cutting were an appropriate response to criminal activity, it would be reasonable to just eliminate law enforcement. Law enforcement responds to criminal activity; it does little to nothing to prevent criminal activity. Automated red light enforcement is an effective response to criminal activity, and it does reduce future criminal activity. Why is the Sheriff’s Office and the City of Sacramento not interested?

If you think that direct law enforcement of red light running is a good replacement, you would be wrong, for two reasons. One, almost no enforcement of motor vehicle violations occurs anymore, other than some enforcement of speeding. Two, the law enforcement practice of pretextual stops, stopping people of color for traffic violations to search for other violations, and to intimidate people of color, results in law enforcement violence against drivers of color.

One of the useful things the city was doing to reduce traffic violence is no longer. Don’t you feel safer now? You can visit the city’s Red Light Running Program page, in case you wish to leave condolences, remembrances, or flowers.

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.

pandemic of red light running

There is a pandemic of red light running in Sacramento, and probably everywhere else. There have always been some red light runners. But since the pandemic emptied many streets of prudent drivers and left them wide open to egregious violators, the problem is much worse now. I am not talking about drivers who ignore or speed up on yellow, and are still in the intersection when the light turns red, I am talking about drivers who enter the intersection when the signal is already red. Often, they speed up approaching the intersection, guaranteeing that any crash will be more serious.

I know many people will not believe this, or will offer up one of many windshield perspectives on why this is not really a problem: bicyclists run red lights all the time and pedestrians jump into the street, so that crashes are their fault and not the fault of the driver. Bullshit. This is an intentional behavior by people who know that they are driving in a dangerous manner, but think they’ll get away with it. And they often do, since other drivers and walkers and bicyclists mostly know not to enter an intersection without looking to see if any of these criminals are coming.

So, if you are a doubter, I ask that you spend time observing a busy or moderately busy intersection. It probably won’t take more than 10 minutes before you see someone run a red light. This behavior truly is pandemic.

One of my observations is that about 2/3 of these are drivers of high value cars, BMWs and huge pickup trucks being the worst offenders. These people, in the unlikely event that they get a ticket for their violation, probably just see this as a minor expense for driving the way they want to. If you don’t believe that the drivers of different kinds of vehicles behave differently, please see Driving Drunk: Car Models with the Most DUIs.

A walker who steps off the curb when the pedestrian signal gives them the right of way are significantly more likely to be hit, or narrowly avoiding being hit, by these criminal red light runners. Same for a bicyclists or other drivers who enter the intersection when the light tells them it is their turn. The situation is slightly different for walkers, who do have the right of way, and bicyclists and drivers, who can enter the intersection when it is safe to do so. But in all cases, the violator is endangering the lives of others.

Red light running is a behavior that is certain to result, sooner or later, in serious injury or fatality. As such, it should be a high priority for enforcement. Both red light cameras and on-the-ground enforcement are needed, and must continue until this criminal behavior recedes at least to pre-pandemic levels, and then beyond that, until it is eliminated.

Some specifics:

  • red light running tickets should be based on the value of the vehicle, so that high income people with high value cars are penalized at a level that will actually change their behavior, and conversely that low income people are not penalized in a way that leads to a downward spiral
  • all red light tickets, whether camera or on-the-ground, must require an appearance before a judge; short-term suspension of the drivers license should be the default punishment meted out; repeated violations should result in permanent revocation of the drivers license and confiscation of the vehicle
  • law enforcement should prioritize observation of and enforcement of driver behaviors that are most likely to result in serious injury or fatality; these behaviors in my mind include egregious speeding (more than 20% over speed limit), failure to yield to pedestrians in the crosswalk, and of course red light running; CHP really only cars about speeding, but this must change. Other law enforcement agencies are more likely to pay attention to other violations, but still not enough.

Some places have red light cameras to catch red light runners, but many places do not. The City of Sacramento has eleven locations with red light cameras, out of about 900 intersections. Sacramento County and the City of Citrus Heights have cameras, but I’ve been unable to find locations or numbers. Rancho Cordova has four locations. The City of Folsom apparently has none.
