Abstract
 Analyzing a Drivers Stops and Purpose from GPS Data Track: Transportation Author(s): Christian Würtz The AKTA project was carried out in 2001 to 2003, examining the effects of introducing road pricing in the greater Copenhagen (Denmark) area. Data was collected as GPS points with 1-second intervals and map matched to a highly accurate map. In the process of analyzing the change in driver behavior, it was essential to distinguish between different kinds of stops. In other words, it was important to distinguish between involuntary stops (e.g., stops because of traffic congestion) and deliberate stops (e.g., a parent dropping off their children at a school). A VB program that made extensive use of the buffer and clustering engine was developed to solve this problem. Based on a detailed land-use map, time of day, time extent and location of other stops, it was able to define the stop category and partly the trip purpose.
