Summary

TRL was asked to investigate current developments in cooperative systems, the benefits they could bring to the Highways Agency and the implications for their operations.

4,300 miles of road managed by the Highways Agency in England

The challenge

Cooperative vehicle systems offer a range of potential benefits for road operators which could be linked with the Highways Agency’s key objectives for improved safety, economy and sustainability.

Our approach

Drawing on current projects and recent experiences at the time, TRL provided an overview of the status of developments in cooperative vehicle systems. Our report analysed key applications for the Highways Agency and identified implementation issues. We drew on the experience we gained in the European CVIS (Cooperative Vehicle Infrastructure Systems) project. 

The results

Our report helped the Highways Agency assess the implications of using co-operative vehicle systems on the road network. By taking advantage of in-vehicle devices and reducing reliance on roadside infrastructure, they found they might reduce capital and operating costs. There could be extra environmental benefits and better traffic management, for less congestion and better safety.
