摘要
GPS浮动车作为一种新型的交通信息采集工具已经成为智能交通领域的研究热点。基于经典概率论理论,并考虑了部分交通流特性的GPS浮动车最佳样本数计算方法,提出了基于仿真实验的最佳样本容量确定方法,并采用Vissim仿真软件进行实验,验证了该方法的可行性。
As a new traffic information collection tool, GPS floating vehicle has drawn much attention in ITS. A determination method of sample capacity of GPS floating vehicle was presented based on the classic theory with consideration of some of the traffic flow optimal samples. Based on the Vissim simulation software, the feasibility of the method was proved.
