摘要
将智能公交系统的智能车辆作为交通移动采集的一种方式,详细分析了智能公交系统的数据流程及公交车作为交通探测车的可行性,随后本文根据公交探测车GPS数据的时域图和“时间-距离”图分析了公交车的运行状态,并详细推导了基于公交探测车数据的行程时间估计算法。
In the paper intelligent bus vehicle could be a type of probe vehicle for traffic mobile information collection, System structure and data flow of APTS and the feasibility of bus probe vehicle have been analyzed. The bus running conditions have been gotten according to the GPS data figure in time domain and ＂time-distance＂ figure. And then the bus travel time estimate arithmetic has been researched in details based on GPS data. The results could impel the re,arch and construction of APTS in China with theoretical and practical significance.
