Average Speed Enforcement
Overview
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. It 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 automatic road network configuration during installation and maintenance.
A back-office system is available with the operator 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.
Solution advantages
Effective operations
Invisible infrared illumination allows for 24/7 operation. Despite the loss of color components with infrared illumination, clear and discernable visual evidence is generated by the system. Speed enforcement for sections is a more robust solution than spot-speed measurement systems. The fool-proof approach discourages motorists with the tendency to speed to avoid it.
Improved traffic flow
The system effectively reduces speed on entire road sections by means of its implementation. In turn, adherence to optimal speeds prescribed for the road sections contributes significantly to the overall traffic flow. Distance is determined up front, time between two points is determined by a very accurate and fail-safe GPS-based measuring device.
Decrease of offences and incidents
It was assessed from operational environments that in majority of the road incidents, speeding behavior of motorists play a significant role. The system decreases the instances of offences considerably: from 20% to 1%, that in turn reduces road incidents. Our systems are certified to comply to the legislation for speed enforcement devices in the Netherlands and Belgium. Some countries have similar certification processes we can prepare for, usually by working with local partner. If these processes are not in place, ARS has the expertise to provide advise based on best practices.
Reduced environmental impact
Since vehicle emissions significantly increase with higher vehicle speed, speeding has adverse effects on carbon emissions. The system reduces environmental impact by means of reducing the emission caused at higher speeds. Despite the share of electric and hybrid vehicles in the overall vehicle population, the factor is still rated to be significant.
Case study
Highways in the Netherlands
We have successfully 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
