基于车头时距稳定性影响阈值的常规公交系统优化
发布时间：2018-09-18 18:01
【摘要】：常规公交系统是城市公共交通的重要组成部分,其合理的线网规划和调度设计可有效提高系统的运行效率和可靠性。公交线路长度关系到公交运营服务水平及其经济效益,该长度不仅受城市自身发展趋势影响,同时还受城市居民的公交出行心理和行为影响。在满足交通需求分布的基础上,不同的公交线路长度和布局模式组成会导致不同的车头时距稳定性。常规公交调度系统的水平直接决定着公交运营质量的好与坏和公交系统的吸引力,通过提高常规公交的车头时距稳定性可以大大的减少常规公交集结运行给乘客与公交企业造成的时间、金钱等的损失。因此有必要基于车头时距稳定性对常规公交系统进行优化。 本文从常规公交车头时距稳定性出发,运用SP和RP法调查常规公交车头时距稳定性影响下的乘客出行选择行为、解析其分布规律,确定车头时距稳定性影响阈值；通过跟车调查,统计公交中间站点公交车辆集结或空白运行的分布规律,并分析其原因；然后应用VISSIM仿真软件分析不同线路长度、线路组合方式与公交车头时距稳定性的关系及不同驻站站点选择、驻站时间与公交车头时距稳定性的关系；最后,构建以平均附加出行时间最短为目标的公交线路模型；分析不同公交驻站方案与公交车头时距稳定性的关系,基于常规公交车头时距稳定性影响阈值,进行以平均附加出行时间最短为目标的长、短间隔公交驻站位置、驻站时间问题研究,最终确定常规公交的最佳线路长度及调度中的驻站位置、驻站时间。
[Abstract]:Bus routine system is an important part of urban public transportation, and its reasonable network planning and dispatching design can effectively improve the efficiency and reliability of the system. The length of bus line is related to the level of public transport service and its economic benefits. This length is not only affected by the city's own development trend, but also by the city residents' psychology and behavior of public transport travel. On the basis of satisfying the distribution of traffic demand, different length of bus route and composition of layout mode will lead to the stability of different front distance. The level of routine bus dispatching system directly determines the good and bad operation quality of public transportation and the attraction of public transportation system. By improving the stability of bus front distance, it can greatly reduce the loss of time, money and so on caused by mass transit assembly and operation to passengers and public transport enterprises. Therefore, it is necessary to optimize the bus system based on the headspace stability. From the point of view of the stability of bus headspace, this paper uses SP and RP method to investigate the passenger travel choice behavior under the influence of the headspace stability of the conventional bus, to analyze its distribution law and to determine the threshold value of the influence of the head-length stability. Through car-following investigation, the distribution rules of bus assembly or blank operation at transit stations are analyzed, and the reasons are analyzed, and then the different line lengths are analyzed by using VISSIM simulation software. The relationship between route combination mode and bus head-time stability, the choice of different stations, the relationship between stop time and bus head-time stability; finally, the construction of the bus line model with the shortest additional travel time as the goal; This paper analyzes the relationship between different bus stop schemes and bus head-space stability. Based on the threshold value of conventional bus head-space stability, long and short bus stop positions with the shortest average additional travel time are carried out. In order to determine the optimal length of the bus line, the location and time of the bus stop in the dispatching, the study of the standing time is carried out.
