Reliability degree estimation of traffic information based on floating car

According to the fact that the quality evaluation process of traffic information estimated by floating cars is neglected or on which models used are unreasonable in existing researches, which lead to blind application of traffic information for users, a method for estimating the reliability degree of traffic information based on floating car is designed considering sample sizes of floating car, and verified with simulated data based on part road network in Changchun, China. The results show that the reliability degree of traffic information based on floating car can be obtained reasonably and accurately using the method in this paper.
