Abstract EN
Floating car equipped with GPS to detect traffic flow has been widely used in ITS research and applications.
The trajectory estimation is the most critical and complex part in the floating vehicle information processing system.
However, the trajectory estimation would be more difficult when using the low-frequency data sampling because of the high communication cost and the numerous data.
Specifically, the ordinary algorithm cannot determine the specific vehicle paths with two anchor points across multiple intersections.
Considering the accuracy in map matching, this paper used a delay matching algorithm and studied the trajectory estimation algorithm focusing on the issue of existence of a small road network between two anchor points.
A method considering the three multiobjective factors of signal control and driving distance and number of intersections was developed.
Firstly, an optimal solution set was acquired according to multiobjective decision theory and Pareto optimal principles in game theory.
Then, the optimal solution set was evaluated synthetically based on the fuzzy set theory.
Finally, the candidate trajectory which is the core evaluation factor was identified as the best possible travel path.
The algorithm was validated by using the real traffic data in Wangjing area of Beijing.
The results showed that the algorithm can get a better trajectory estimation and provide more traffic information to traffic management department.
