【摘要】：当今,空气污染已经严重威胁到了人类的生存与发展。为了缓解这一重要问题,人们发出了“绿色出行”的倡议。而公共自行车作为绿色出行交通工具的一种,其独有的简单、方便、灵活的优势,为人们解决了城市交通中存在着的“最后一公里”的问题。但是随着公共自行车系统规模的不断增大、使用频率的不断增加,为其管理带来了一系列的问题。因此,本文从公共自行车系统中租赁点车辆流模型、拓扑结构、仿真模型和动态平衡机制等方面进行研究,为公共自行车系统布局优化设计提供理论和应用支持。首先,本文基于系统运营数据的时空分析方法,以温州市鹿城区为例,在充分考虑各类外部影响因素的情况下,通过对系统中的运营数据进行挖掘分析,建立了不同影响因素下的租赁点车辆流变化曲线,进而给出了不同类型租赁点的车辆流特征模型。然后,本文通过对公共自行车系统中租赁点之间的关联关系进行分析,得到了租赁点组成的网络拓扑结构,统计出租赁点间的关联度,建立了租赁点动态分布的仿真模型。本文利用Matlab仿真工具,基于租赁点间的关联度及其车辆流模型,对各种租赁点网络进行仿真分析。最后,本文根据公共自行车系统中租赁点的仿真模型和分析结果,构建了相应的租赁点动态平衡理论。依据这些平衡理论,建立了不同类型租赁点的平衡状态与布局模式。对于不能达到平衡状态的租赁点,提出了相应的布局二次优化策略和设计方案。
[Abstract]:Nowadays, air pollution has seriously threatened the survival and development of human beings. In order to alleviate this important problem, people issued the "green travel" initiative. As a kind of green travel vehicle, public bicycle has its unique advantages of simplicity, convenience and flexibility, which solves the "last kilometer" problem in urban traffic. However, with the increasing scale of public bicycle system and the increasing frequency of use, it brings a series of problems to its management. Therefore, this paper studies the vehicle flow model, topological structure, simulation model and dynamic balance mechanism of public bicycle system in order to provide theoretical and application support for the layout optimization design of public bicycle system. First of all, based on the space-time analysis method of system operation data, taking Lucheng District of Wenzhou City as an example, taking all kinds of external influence factors into full consideration, this paper analyzes the operation data in the system by mining. The curve of vehicle flow at rental points is established under different factors, and the characteristic model of vehicle flow at different rental points is given. Then, through the analysis of the relationship between lease points in public bicycle system, the network topology of lease points is obtained, and the correlation degree between lease points is calculated, and the simulation model of dynamic distribution of lease points is established. In this paper, the Matlab simulation tool is used to simulate and analyze all kinds of rent-point networks based on the correlation degree between lease points and the vehicle flow model. Finally, according to the simulation model and analysis results of the rental point in the public bicycle system, the dynamic equilibrium theory of the lease point is constructed. According to these equilibrium theories, the equilibrium state and layout model of different types of leasing points are established. For the leasing point which can not reach the equilibrium state, the corresponding layout quadratic optimization strategy and design scheme are put forward.
