摘要:

郊区及新建市区等人口稀疏区域的人们乘车出行多有不便,为消除这类区域乘车出行的缺陷,进行了出行算法研究.本文提出了矢量匹配算法和接载路径算法.首先,对出行者请求的出发地和目的地位置信息与服务区域道路网主路线进行方向匹配;其次,对所有匹配成功的请求位置信息进行全局最优路径规划;最后,根据路网模型并结合出行算法给出实验数据分析和结论.研究结果表明:本文提出的出行算法具有常规公交车所不具备的人性化的点到点服务特征,服务品质高,乘车费用较出租车费用实惠,平均每位出行者的乘车时间在可接受范围内,乘客满意度较高,可以很好地满足人们出行方便快捷的意愿.

Abstract:

People in sparsely populated areas such as suburbs and new cities traveling by bus have much inconvenience. To eliminate the defect of bus travel in these areas, a travel algorithm research is conducted. This paper proposes two algorithms, vector matching and pick-up path. Firstly, to match the direction between traveler’s departure and destination location information and main road network route of service area. Secondly, a global optimal path planning is conducted for all successful matched request location information. Finally, experimental data analysis and conclusion are given based on the road network model and travel algorithm. The result shows that travel algorithm have the characteristic of humanized and point-to-point services to be different form regular bus, service quality is high, and travel cost is cheaper compared with taxi fee. In addition, average traveler’s journey time is also within acceptable range, passenger satisfaction is higher, and the algorithm can well satisfy the wishes of people to travel conveniently and quickly.

Key words: urban traffic, travel algorithm, vector matching, sparsely populated areas, small bus, pick-up path planning
