Research on Speed Distribution Characteristics of Basic Sections of Urban Major Arteries
摘要
Abstract
Speed is a basic parameter for describing the state of vehicle operation. Mastering the speed distribution characteristics of a basic section of the urban major arteries is a basis for the follow-up studies. Based on the survey of two urban major arteries in Nanjing, the general statistical methods were used to study the speed distribution characteristics of the basic sections of the two urban major arteries. First, the speed distribution forms of different types of the major arteries were qualitatively analyzed by fitting the survey data. Second, the central tendency and dispersion degree of the speeds were analyzed from the whole and transverse section aspects. The research results show that the speed distribution forms of the urban major arteries are mainly related to the driving freedom and traffic condition, the state of traffic flow would have different impaction on the speed distribution parameters. The results would provide a scientific basis and data support for planning, designing, controlling, manageing and evaluating of a urban main artery.关键词
