Validating travel times calculated on the basis of taxi floating car data with test drives

In contrast to traditional traffic sensors like induction loops, the position data from fleets of Probe Vehicles are an excellent technology to determine travel times which are needed for information and route guidance systems. This contribution describes an application of a taxi-PVD system in Hamburg with about 700 taxis. Here, an information system was set up which delivers travel times accessible via internet. The information is validated with test drives of independent vehicles driving on the routes. It is demonstrated that a taxi-PVD system like this is able to deliver reliable information about travel times.
