AVERAGE SPEED ENFORCEMENT
The average speed enforcement system measures the speed of every passing vehicle in a monitored section of the road. It intelligently applies the lane characteristics, dynamic speeds limits displayed to motorists and the vehicle class to verify whether the average speed of the vehicles are within allowed limits. It plugs the gap left by spot speed systems leading to a precarious tendency from motorists to rapidly slow down and then accelerate at speed measuring points to avoid potential penalization.
The main purposes of the Average Speed Enforcement system are improving traffic safety, reducing environmental impact and bettering traffic flow. The system is highly accurate and reliable to attain a positive review by the public.
The system uses image processing and optional sensor integration to capture maximum speed offenders based on their average speed over an entire road section. Systems of ARS T&TT use non-invasive video detection and classification technology. Roadside systems have integrated GPS sensors for accurate timers and for speedy road network configuration during installation or maintenance.
A back-office system is available with operator power tools for verifying violation processing, quality augmentation with redundant data-processing algorithms, archival of Judicial evidence in a tamper-proof manner, automatic dispatch of violation records to authorities for further processing and monitoring the system operations.
Use case: Highways in the Netherlands
We succesfully implemented 5 Average Speed Enforcement systems on the A2, A10, A12 and A20 highways in the Netherlands. Over the past years, these systems have significantly reduced the number of accidents on these roads, as well as the environmental impact caused by speeding vehicles.
