本文从公路网的交通流特征、道路特征及服务水平等三方面来定量分析公路网的道路与交通特征,以公路网交通流量、交通密度、行车速度和公路网行程时间来反映公路网交通流特征,以路面铺装率、技术等级、路网容量来反映公路网道路特征,以事故率、饱和度、里程饱和率、运输成本等来反映公路网服务水平,并对提出的评价指标进行了波动度分析,最后以山西省干线公路网为例,用道路与交通特征参数,对其进行现状分析。
This paper quantitatively analyzes the road and traffic characteristics of highway network from three aspects of the traffic flow characteristics, road characteristics and service level of the highway network. Traffic flow, traffic density, driving speed and road network travel time are used to reflect the traffic flow of highway network Characteristics, road pavement rate, technical level, road network capacity to reflect the characteristics of road network, with accident rate, saturation, mileage saturation rate, transportation costs to reflect the service level of the highway network, and the proposed evaluation index Volatility analysis. Finally, taking the trunk road network in Shanxi Province as an example, this paper analyzes the status quo by using the road and traffic characteristic parameters.
