April 2: Optotraffic is currently deploying the largest array of portable speed cameras in the U.S. in Prince George’s County, Maryland. We were pleased to see more dramatic proof that our cameras reduce speeding in school zones. The Police Department reports that in a comparison of a dozen deployments in January and February this year, speeding citations fell an average of 42.58 percent; from a low of 19 percent to a high of 75 percent! When drivers know that speed cameras are present, they simply slow down and that’s good for the school kids, crossing guards and the entire community.
Yet More Evidence That Automated Systems Reduce Speeding

Posted by in Laser Speed Sensor | News | Optotraffic | Portable Speed Enforcement | Safety | Schools | Speed Camera | Speeding - (0 Comments)October 25: The Traffic Group, Inc. is a well-regarded research firm in Baltimore. It did a “before” and “after” study of four jurisdictions in Maryland that deployed Optotraffic equipment to see if there was a change in driver behavior after the Optotraffic units were in place. There certainly was! All four locations showed significant improvement. The longer the speed cameras were in place, the more drivers obeyed the speed limit.
The City of Seat Pleasant showed the most dramatic improvement. Optotraffic deployed its equipment near Seat Pleasant Elementary School. Before deployment only 7.6 percent of the drivers obeyed the 30 mile per hour speed limit on Eastbound Maryland Route 704. By the end of the study that number had risen to 75.6 percent—an 895 percent increase. More significantly, crashes in the school zone fell dramatically. In fiscal 2010 there were 25 property damage crashes and 20 crashes involving personal injury in the school zone. After installation of the cameras, there were only two property damage crashes and one personal injury accident.
Signs notifying drivers of the speed cameras were prominently posted in the school zones and the Optotraffic speed camera equipment was clearly visible. Nonetheless, driver behavior appears to adapt over time rather than immediately. According to The Traffic Group in its Riverdale Park report, “Generally, the number of violations decreased steadily each month of operations.”
PORTABLE SPEED ENFORCEMENT – An Efficient Solution For Public Safety
Posted by in Portable Speed Enforcement | Speed Sensor Systems | Speeding - (0 Comments)Every week across the country people die or become injured due to speed related accidents. Whether they are motorists, pedestrians or highway construction workers, each instance is a tragedy that can and should be avoided.
Speed sensor enforcement systems, using lasers and other imaging technologies, are proven systems enabling municipalities to significantly reduce the number of traffic violations and crashes. It has been widely shown that the perception of the risk of getting a ticket strongly influences motorists’ driving behavior (IIHS – 2009 Statement before Maryland Senate Committee on Judicial Proceedings on Senate Bill 277.)
Optotraffic, based in Lanham, Maryland and with more than 50 employees, provides automated laser speed sensor and camera technology and support services to local governments – - to reduce speeding in school zones and increase public safety in many jurisdictions, municipalities and towns. Thirty units operate in more than 12 localities in the State of Maryland.
The company uses in-house developed and patented space laser technology – LIDAR, an application of our company’s pioneering expertise in the space industry – that provides highly-accurate, low cost traffic monitoring and enforcement solutions. The company delivers sophisticated, accurate, secure automated speed enforcement systems.
The Portable Solution
Optotraffic was the first provider in Maryland to deploy automated laser sensor speed enforcement programs following passage of the Maryland law authorizing such enforcement in school zones, and also is the provider in the State with experience in primarily portable systems.
These patented portable systems require no attendant on site. The camera-part of the system – - used to document the presence and identity of speeding autos – - uses space technology, digital photography, and fast processing speed. It is housed in a small 4-foot wide trailer suitable for deployment on any street. It works with ease in dense traffic and multiple lanes simultaneously.
Because this unique camera system is portable, one camera system enforces multiple locations. Public safety improves over a large geographic area.
And the system can be deployed very rapidly, usually within four hours to respond flexibly to different traffic conditions and enforcement needs.
Portable Versus Fixed or Mobile Systems
Fixed installations generally require many months to put into place, and are generally used only in high-volume locations. Since the systems are so effective, they soon accomplish the goal of reducing speed. Since they are fixed in place at that location, and unable to be used to solve other problems, they are not available to reduce speeding at other locations.
Mobile, vehicle-mounted installations are of very limited utility, and usually involve parking a vehicle by the side of the road. Besides typically being able to enforce only one lane at a time, they require manpower to operate the systems.
Optotraffic’s portable solution provides a state-of-the-art speed enforcement solution. Features include:
- True lane-specific undetectable across-the-road speed sensing
- Completely autonomous operations with no operator required
- A whisper-quiet diesel generator to eliminate the need for power hook-up
- Mast-mounted technology, allowing the system to “look over” multiple lanes to catch violators on all lanes of a multi-lane road.
