T0647 Close Following

Description

National Highways is committed to reducing injuries resulting from Road Traffic Collisions (RTC). 
Early in 2015 Task 352 facilitated initial trials at an off-road facility to identify whether sensor technology could be developed to measure the frequency of - and enforce - close following offences.  At the time, four of the six systems showed potential.
Subsequently Task 520 subjected the promising prototype systems to further, and more complex, off-road trials.  These additional trials provided the system suppliers with important testing and development time at an off-road facility.  Trials were conducted using a greater number of vehicles, various vehicle types (including motorbikes) and more scenarios.
All four prototype systems involved in Task 520 were believed to be capable of supporting the on-road trials to gather data to understand the extent of the close following problem on the network. 
SPATS Task 1-022 took the first equipment to a live roadside site and analysed the performance of the systems.
