It also gives an idea about the required penetration rate of floating car data needed to achieve a certain degree of improvement. The study uses real loop detector data from the region of Amsterdam collected for over a year, a route generating algorithm for in-car routing advice, and emulated floating car data to generate the routing advice. The case with in-car routing advice has been compared to the base case, where drivers base their routing decisions on average knowledge of travel times in the network. The improvement in total delay using the in-vehicle system is dependent on penetration rate and accuracy of the floating car data and varies from 2.0% to 3.4% for 10% penetration rate. This leads to yearly savings of about 15 million euros if delay is monetarised using standa...

A roadmap is presented that shows the anticipated development of crucial technologies for people movers. A critical technology is obstacle detection. An obstacle detection system is presented based on stereo vision and radar that uses sensor fusion and tracking for obstacle detection. The obstacle detection system was tested on an autonomous test vehicle and showed promising results.
