Abstract: From traffic information coverage perspective, the configuration optimization of probe vehicle system is explored.First, the coverage status is analyzed based on the reviewing of existing studies.Then, a coverage model and the optimization model of the number of probe vehicle is developed considering the minimum coverage requirement, the coverage marginal contribution rate of the number of vehicles and other restrictions.Finally, the model is used to optimize the probe vehicle system of Shenyang city of China.The result shows that the model works with high reliability and portability, which leads to a prediction accuracy of 96.1%.The optimization guarantees the lowest cost and the basic requirement of the traffic information coverage, which is of great reference value for the configuration of probe vehicle system.

摘要: 本文从交通信息路网覆盖率角度出发,对浮动车系统进行配置优化研究.在回顾国内外相关研究的基础上对覆盖率现状进行分析,建立浮动车系统交通信息路网覆盖率模型;考虑最低覆盖率要求和车辆数对覆盖率的边际贡献率等限制条件下,建立浮动车数量优化模型;最后运用此模型对沈阳市浮动车配置进行优化分析.结果表明,覆盖率预测结果精度达96.1%,模型具有较高的可靠性和推广性.浮动车数量的优化结果在满足交通信息所需覆盖率的同时,也保证了浮动车系统运营费用的影响,对于浮动车系统配置具有重要参考价值.
