Abstract

This paper addresses how to manage the location history data collected from the Jeju taxi telematics system and analyzes the effect of the report position in a link to the average speed and stop probability. The analysis cannot only quantify how much the speed value, included in each location report, will be accurate in calculating the actual link speed but also locate bottle-neck links. Using the road network represented by an ESRI shape format, a map match scheme is designed to calculate the position from one of the two end points. Then, the statistical analysis runs database queries on the vehicle speed and stop probability for all records, for the records having the passenger-on status, and for the records belonging to the hot links. The investigation finds that the speed difference between the middle and end points of a road segment can reach 13 kmh on average and locates intersections that blocks vehicle traffic.
