How to Evaluate Speed Camera Locations Today

Speed and red-light cameras have long been considered practical tools for reducing Baltimore City streets’ accidents, injuries, and deaths. BCDOT evaluates locations prone to accidents and traffic violations when selecting camera locations, considering resident input as they choose camera positions. Cameras record photo/video evidence of violating vehicles, including their license plate numbers, and take photo/video evidence of violations, such as photo evidence captured from breaking vehicles — making an accurate speed camera ticket easily disputable using Defense Doc.

Various kinds of speed cameras monitor the road in New York City. While some cameras focus on enforcing red light and speeding laws, others serve specific functions. To prevent incurring unnecessary fines for speeding violations in NYC, individuals must understand which types of cameras exist to avoid speeding tickets.

City officials usually decide where and when a traffic camera should be installed based on factors like crash data, engineering feasibility, and community and elected official requests. Unfortunately, many areas where speed cameras are needed in NYC don’t yet have them; for instance, at Flatbush Avenue and E 17th Street intersection, where the driver ran a red light and hit a pedestrian, as well as many other roads throughout all five boroughs.

Although the city claims that its speed camera selection process uses a “data-driven approach,” some drivers remain concerned by disproportionate ticketing in low-income communities of color. Although cameras do not discriminate on race, wide speedway-like roads in these neighborhoods haven’t been updated for safety compared to White areas – according to a ProPublica investigation, 38 percent of tickets sent out were for speeding violations!

Traffic sensors serve a different function: cameras designed to measure traffic flow and identify lights. These are typically installed on poles near stoplights or poles near traffic signals and don’t tie into ticket-issuing systems. Meanwhile, Automatic Number Plate Recognition (ANPR) cameras use artificial intelligence combined with cameras to read license plates; mobile cameras mounted to police cruisers may also read them automatically.

City governments often utilize speed cameras in some form; private companies can also set up speed cameras for specific uses – for instance, monitoring construction zones or high school zones when schools are in session – although such personal speed cameras are illegal in New York State.


Speed cameras used in an enforcement and education program can dramatically decrease crashes in developed nations, whether fixed or mobile camera programs are used. While selected camera programs tend to work better in rural settings than urban ones, and their exact size of reduction varies by type and local scene (speed cameras tend to be more effective in rural than urban locations), their impact may differ according to type and local setting as well; for instance, unmarked mobile camera programs produce more excellent traffic volume suppression, broader halo effects, but lower percentage reductions of severe crash injuries.

New York City camera program results demonstrate this effectiveness, showing that cameras are highly effective on dangerous roads across all five boroughs. In particular, Grand Concourse and Union Turnpike in the Bronx saw a 72% reduction, Fourth Avenue saw an 89% decrease, and Rockaway Boulevard and Gun Hill Road experienced over 81% drops – all results that indicate there are safe streets where additional speed cameras could help save lives and improve safety in New York City.

Cities may worry that speed cameras could negatively impact low-income communities; however, it’s important to remember that these devices target reckless driving behavior rather than community sentiment, race, age, background, or legal/economic status. Furthermore, unlike physical speed enforcement by police officers, which may appear biased or discriminatory towards specific groups, speed camera operations are impartial and non-discriminatory.

Speed cameras – and all forms of enforcement – depend heavily on their ability to influence desired changes in behavior, which requires swift and unavoidable detection with sufficient severity to deter. This includes clear warnings about speeding, police patrols to reinforce that message, quick yet fair application of penalty without avoidance through corruption, and a public perception that these features exist.

A practical evaluation is critical to maximizing the safety benefits of any speed camera program. A comprehensive assessment should include comparative analyses using matched controls, randomized controlled trials, and other rigorous methodologies; strong communication about any new or expanded camera programs to alert communities of any changes coming (which research shows increases effectiveness by creating general deterrence).


Many factors contribute to the vast safety benefits reported from camera programs. Some can be predicted from systematic features in a country or state, such as the size and breadth of enforcement area (i.e., road length covered by cameras) and how benefits are calculated. In contrast, corruption levels and the effectiveness of speeding penalties must be addressed through policy change or governance structures.

The impact of cameras depends heavily on whether drivers understand that they may be caught and their awareness and perception of risk. This factor becomes especially pertinent in environments where drivers disregard speed limits, such as urban areas or school zones, where cameras have proven successful at significantly decreasing speeding. Conversely, red light violators only benefit from cameras as they catch little.

Drivers may respond less effectively to cameras if they are poorly placed or visible, such as is often the case in Australia, where drivers have learned to slow down just enough to avoid being caught by cameras, creating what is known as a “halo effect,” with speeding drops occurring more broadly than would otherwise be expected. Other countries, including the US, have observed greater concentrations of cameras yield more substantial benefits.

One of the primary factors limiting camera effectiveness is their hours of operation. For instance, New York City’s cameras have proven effective at reducing speeding around schools. Still, state law dictates they be turned off overnight and on weekends – this reduces overall effectiveness and increases crash risks when they’re not running.

Debates regarding speed cameras continue, and many cities and states have already implemented them to enhance roadway safety. While studies show their benefits, their exact effects vary between jurisdictions. So, when considering whether or not to implement one program, these differences must be considered when making this decision.
