Caltrans trials Xerox's Passenger Detection System
Xerox's Passenger Detection System has been trialled in California and compared with the state's team of human counters giving some interesting results, as Colin Sowman discovers. Like others adopting high-occupancy and high-occupancy vehicle (HOV) lanes for congestion management, Caltrans has faced challenges with compliance in what has been effectively an 'honour system' with drivers...

Traffic engineers have traditionally been forced to operate with limited data regarding the performance of their arterials. Traffic studies are often commissioned once every three years, over a few days, to get an updated estimate of utilization.
