Method for determining grade allocation of urban roads

Abstract

The invention relates to a method for determining grade allocation of urban roads, which is used for determining grade allocation ratio of the urban roads. The method comprises the following steps: firstly, determining parameters in a microscopic share ratio model of various traffic modes influencing the grade allocation, wherein the traffic modes at least comprise three motor vehicle traffic modes of automobiles, motorcycles and public buses; and then, according to a coupling relation between a priority trip distance of each traffic mode and a trip distance undertaken by each grade road, acquiring the trip distance of each traffic mode on each grade road, and finally acquiring the road grade allocation ratio suitable for the various traffic modes. Therefore, the technical proposal of the invention has the characteristics of comprehensiveness of giving attention to various motor vehicle traffic modes, objective and scientific properties of considering the coupling relation between the priority trip distance of each traffic mode and the trip distance undertaken by each grade road, and the like, namely the method for the grade allocation of the urban roads is more reasonable, achieves effective utilization of resources, and is convenient for people to trip.

Description

technical field [0001] The invention relates to a method for determining the grade configuration of urban roads, in particular to a method for determining the grade configuration of urban roads considering the characteristics of different travel distances of various motor vehicles. Background technique [0002] my country is in a period of rapid economic growth. With the acceleration of urbanization and the rapid growth of motor vehicle ownership, the urban traffic environment is deteriorating day by day. In order to alleviate traffic congestion, my country has also increased investment in urban road construction, but the idea of ​​"impatient for success" makes cities only focus on the construction of express roads and arterial roads, ignoring the construction of branch roads. In addition, the growth of road supply is also ineffective. On the contrary, the trunk road bears short, medium and long trips of motor vehicles, making the expressway unhappy and the trunk road unsmoo...

Problems solved by technology

[0011] 2) Ignoring the coupling relationship between the advantageous travel distances of each mode of transportation and the travel distances undertaken by roads of all levels

However, the existing research does not consider the coupling relationship between the superior travel distance of the transportation mode and the travel distance borne by roads of all levels, which is not scientific.
