摘要
阐述了基于浮动车数据的实时交通参数如平均速度、行程时间、OD矩阵等的估计方法,并利用V iss im仿真软件进行了验证。实验结果表明,笔者提出的交通参数估计方法具有较高的精度。
Fixed traffic data detector can not satisfy the demand of Intelligent Transportation System （ITS） because of its high cost and low coverage area. Floating car system has many advantages such as low investigation, large coverage area, high precision, etc. This paper describes the floating car system, presents the calculation models of average velocity, journey time, and OD matrix. The result shows that the calculation models have high accuracy.
