基于少量探测车的城市路段平均行程时间估计
Urban Road Link Travel Time Estimation Using Small-Sized Probe Reports
摘要
Abstract
Compared with traditional traffic detectors, the probe vehicle system (PVS) can collect the travel time directly and cover broader in space and time span. However, a new method to estimate link travel time is needed to cut down the operation cost of PVS. This paper proposes a method using a very small-sized sample, based on the correlations among the mean link travel time of the stop group and the nonstop group, the proportion of nonstop group and the others. This method is examined by a simulation model. The results show that the proposed method is superior to traditional methods, especially for the congested traffic.关键词
