Scientists were meeting Cambridgeshire County Council highways chiefs this week to discuss county-wide roll out of an intelligent lamppost being progressed by the Cambridge University computer laboratory.
Sensors for counting supermarket queues are anonymously recording vehicle flows and speeds in a prototype at a test site on Madingley Road, the main link between the M11 and the city centre.
Project leader, Dr David Evans, said: ‘The aim is to provide traffic data at low cost, while avoiding video, with all its related privacy issues.
‘We are currently working on an additional acoustic sensor that could help detect individual vehicle types, for example, buses’.
He hopes the county will consider the concept for its next lamppost-replacement programme.
The initiative forms part of the 2005-2010 Transport Information Monitoring Environment (TIME) programme, aimed at improving traffic monitoring in Cambridge.
