Floating Car Data-Based Algorithm for Calculating Vehicle Queue Length at Intersections
There are many speed stop point records in the floating car data (FCD), which has some spatial relations with the vehicle queue length in front of intersection. A new method for computing vehicle queue length in front of intersection based on FCD of stop points was described. First, the data on normal queue points are calculated from stops by map matching based on the geographic location of the stops, the continuous relationship between the queue points and movement points and the relative location to the intersections on a road link. Second, the relative positional relationship of FCD at intersections is calculated on the basis of the data on normal stops and by two-step statistics. Vehicle queue length at intersections is then calculated on the basis of the stopping distances of floating cars and the distribution density at intersections. An example is presented to demonstrate how the algorithm functions.
