基于GPS与IC卡的公交OD量采集方法

公交OD量是公交调度管理及线网优化的基础。传统的获取公交OD量的方法需要进行大范围的个人出行情况调查，消耗大量人力物力，且数据更新缓慢。随着GPS技术与IC卡在公交系统中的广泛应用，提出了利用公交车GPS定位与乘客IC卡刷卡信息来获取公交OD量的新方法。利用这一方法对广州某段时间的公交车GPS定位和羊城通数据进行了实际分析。试验结果表明这一方法是有效的。

Approach to Collection of Bus OD Matrix Based on GPS and Bus Intelligent Card

Public transportation OD matrix is fundamental to public transportation dispatch and network optimization. Traditional approach to collection of pubic transportation OD matrix needs a lot of personal trip surveys, which will expend a 10t of manpower and material resources and renovate data by inches. With the application of GPS and intelligent card in public transportation system, this paper proposes a new approach to collection of OD matrix based on GPS and intelligent card. Finally, the developed approach is implemented with Yangchengtong and public bus GPS positioning data of Guangzhou in some months and the computational performance is analyzed. The result indicates that the approach is efficient.
