Title: Apparatus and method for managing traffic
Inventor: HILDITCH ALBERT STEPHEN
IPC: G08G1/042
Filed: 2013-09-27
Abstract: First and second values are received from traffic count sensors 4,5 indicating a number of road vehicles passing respective first and second positions 4a,5a in a first (i.e. the same) period. A third value is received from the first sensor 4 indicating a vehicle count at the first position during a second period. The third value is modified based on a difference between the first and second values. Vehicle counts are thus cleansed of errors caused by sensor drift in sensor 4. The time periods may be different days. The vehicle count may be modified only in dependence on whether a below-average number of lane changes is likely in the respective road section e.g. due to a traffic management policy such as variable speed limit, lane closure or extra lane provision. The sensors may be inductive loops in the road surface and the vehicle counts may be used to determine transit times along a stretch of road.
