Abstract

In contrast to traditional traffic sensors like induction loops, GPS-position data from Floating Car Data fleets (FCD) are an excellent technology to determine travel times which are needed for traffic information and route guidance systems. This contribution is about the validation of a taxi-FCD system in Berlin with more than 4000 taxis, from which a traffic state map and travel times are generated continuously. The validation is done by analyzing the data measured on five weekdays by test drives with GPS-equipped vehicles on three selected arterial routes. The travel times which are calculated from the taxi-FCD system are in this contribution – in contrast to earlier publications – only based on the most current taxi data delivered and thus do not take “historical” information into account. These data are primarily validated via the travel times of the test vehicles, which can be measured exactly with the GPS-information. This way, occurring differences between travel times of the taxi-FCD system and test drives can be analyzed accurately. As a result, the travel time estimates of the taxi-FCD system are validated and stressed for the three routes as a whole as well as for parts of the route.
