"TDS Speed Enforcement and Stolen Vehicle Detection Systems provide the Foundation for Sophisticated Traffic Calming and Speed Violation Enforcement Systems"

Automated enforcement of speed violations has been widely credited with contributing to fatality reductions overseas. This technique is not in common use today in the United States. It has proven to be controversial and politically unpopular in some jurisdictions that have applied it, although progress has been made in gaining acceptance of the technique. Despite these issues, the experience of the international community with this enforcement technique has demonstrated that sustained and intensive enforcement, rationally organized and managed, can alter driver behavior sufficiently to product worthwhile systemwide safety improvement.

Successful speed management initiatives in other countries are of high visibility, are long term, target major portions of the road network, sometimes use intensive enforcement methods, and monitor progress toward publicly declared speed and crash reduction objectives. No U.S. speed management program in operation today is comparable in scale, visibility, and high level political commitment to the most ambitious speed management programs in other countries. The evidence from numerous research studies, synthesized in several credible reviews, is that reducing the mean speed on a road reduces injuries and fatalities in crashes on the road – speed reductions reduce casualty risk. Automatic enforcement is a very efficient method of accomplishing speed reductions. And at the same time the enforcement equipment can be used to identify vehicles of interest including stolen vehicles and amber alert vehicles.

Transport Data Systems offers both stand alone and system solutions for speed enforcement. The SpeedNabber product is a standalone system with built in radar, camera and flash illumination along with a wireless interface. This unit is designed to be used in stand-alone situations where traffic calming is the primary purpose. The unit is particularly well suited to gated residential communities and corporate parking lots. It can also be used by law enforcement for traffic calming in school zones and work zones. Groups of SpeedNabbers can be incorporated into a system for providing speed calming over an extended neighborhood or an entire metropolitan area. For more information please visit the SpeedNabber web site.

TDS also offers single lane and multiple lane high speed systems for implementation on highways. Here the system not only provides for speed enforcement but also provides data for real time detection of vehicles of interest based on their license plates. This can include stolen vehicles and amber alert vehicles as well as vehicles of interest to Homeland Security. The system uses advanced radar and high speed digital cameras with LED flash illumination. A complete system of cameras can provide coverage across an entire freeway. The system can be netted to provide for daily updates of the vehicles of interest and can provide immediately alerts when vehicles of interest pass the checkpoint. It can also be provided with a WIFI interface to connect to enforcement vehicles downstream from the capture point. The system requires only one gantry.
