【摘要】：随着城市的发展和交通网络的扩张,交通供求矛盾日益突出,如何提高城市路网运行的可靠性也受到越来越多的关注。作为城市道路的使用者,不同类型的出行者会表现出不同的出行选择行为,对事物的认知不同,因此不同类型出行者的预留时间会不同。预留时间是行程时间可靠性的评价指标,可以反映路网的随机性和行程时间的稳定性,从而使具有不同预留时间的出行者对路网行程时间可靠性的评价有所区别,因此,基于出行者的预留时间合理划分出行者类型,研究不同类型出行者的路网行程时间可靠性问题更具有现实意义。通过分析现有研究,归纳总结出五类影响路网行程时间可靠性的因素,阐明了预留时间与行程时间可靠性的关系,然后通过从出行者路径选择行为和交通网络设计层面总结出四种不同的出行者类型划分方式,并对每种划分方式存在的不足做了具体分析,由此提出基于预留时间的出行者类型划分方式,给出了基于预留时间的出行者类型划分流程,为实际路网中的出行者类型划分提供理论基础。结合理论分析明确了基于聚类分析的出行者类型划分方法,并构建了基于预留时间的离散选择模型,为出行者预留时间影响因素的分析提供理论依据。为了进一步分析不同类型出行者的路网行程时间可靠性,构建了基于预留时间的多类用户交通分配模型,并结合基于预留时间的路网行程时间可靠性计算公式,用于评价路网的整体性能。以深圳市南山区某一区域路网为例,结合SP(Stated Preference,SP)调查数据和构建的模型,对实际路网中的出行者进行划分,考虑不同类型出行者的特征,分析路网交通流量空间分布特征及路网行程时间可靠性,然后分析不同类型出行者比例的不同对路网行程时间可靠性产生的影响,为路网性能的合理评价和相关交通措施制定提供依据。
[Abstract]:With the development of city and the expansion of traffic network, the contradiction of traffic supply and demand is becoming more and more prominent, and how to improve the reliability of urban road network is paid more and more attention. As the users of urban roads, different types of travelers will show different travel choice behavior and different cognition of things, so the reservation time of different types of travelers will be different. Reservation time is the evaluation index of travel time reliability, which can reflect the randomness of road network and the stability of travel time. It is of practical significance to study the reliability of road network travel time of different types of travelers based on the reasonable classification of traveler's reserved time. By analyzing the existing research, five kinds of factors influencing the reliability of road network travel time are summarized, and the relationship between reservation time and travel time reliability is clarified. Then it summarizes four different types of travelers from the aspects of route selection behavior and traffic network design, and makes a specific analysis of the shortcomings of each type. Based on this, the paper puts forward the classification method of traveler type based on reserved time, and gives the flow of traveler type division based on reservation time, which provides a theoretical basis for the classification of traveller type in actual road network. Based on the theoretical analysis, this paper clarifies the classification method of travelers' types based on cluster analysis, and constructs a discrete selection model based on reservation time, which provides a theoretical basis for the analysis of influencing factors of traveler's reservation time. In order to further analyze the reliability of road network travel time of different types of travelers, a multi-class user traffic assignment model based on reservation time is constructed, and the calculation formula of road network travel time reliability based on reserved time is combined. Used to evaluate the overall performance of the network. Taking a regional road network in Nanshan District of Shenzhen City as an example, combining with the survey data and the model constructed by SP (Stated Preference,SP, this paper classifies the travelers in the actual road network and considers the characteristics of different types of travelers. The spatial distribution characteristics of road network traffic flow and the reliability of road network travel time are analyzed, and then the influence of different proportion of different types of travelers on road network travel time reliability is analyzed. It provides the basis for the reasonable evaluation of road network performance and the formulation of relevant traffic measures.
