【摘要】：为改善公交拥挤状况,提高车内舒适度,基于站点OD(origin destination)信息已知的基础上,提出了一种公交线网优化方法.首先,以最大路线长度和换乘次数为约束,构建以人均舒适度最大为目标的公交线网优化模型;其次,采用隶属度函数计算乘客舒适度,并绘制舒适度随乘客数变化的关系图像,以验证优化方法的合理性;最后,运用爬山算法思想,使用交换路线法与邻近线路分担法,按照"由低到高,逐段优化"的原则优化线网,通过调整路线来平衡客流,均衡不同线路公交的利用率.研究结果表明:拥挤线路各站点间舒适度标准偏差由优化前的0.24减小为0.09,站点间的客流不均衡现象得到明显改善;乘客人均舒适度由原来的0.84提高到0.91,提升了8.3%.
[Abstract]:In order to improve the traffic congestion and improve the comfort of the bus, a method of bus network optimization is proposed based on the information of the origin of the bus station. Firstly, taking the maximum route length and transfer times as constraints, a bus network optimization model with maximum per capita comfort is constructed. Secondly, membership function is used to calculate passenger comfort. In order to verify the rationality of the optimization method, the relationship between the comfort degree and the number of passengers is drawn. Finally, using the idea of mountain climbing algorithm, using the method of exchanging routes and sharing the adjacent lines, according to "from low to high," The principle of piecewise optimization is to optimize the line network by adjusting the route to balance the passenger flow and to balance the utilization ratio of different lines of public transportation. The results show that the standard deviation of comfort between stations on congested lines is reduced from 0.24 to 0.09, and the imbalance of passenger flow between stations is obviously improved, and the per capita comfort of passengers is increased from 0.84 to 0.91, an increase of 8.3%.
