Problems solved by technology

Congestion cost research has ranged from the congestion pricing theory in the 1960s and 1970s, to the urban congestion cost estimation system proposed by Europe and the United States in the 1990s, to various congestion cost calculation methods proposed by many scholars in my country. Reflects the current situation of congestion, but there is still no unified method for quantitative analysis of congestion cost

Embodiment example

[0065] Implementation case: Taking Zhengzhou City as an example, estimate the extra cost of traffic congestion in Zhengzhou City in 2013, and further explain the congestion cost estimation method through the cost estimation process.

[0066] 1. Investigate the speed of different vehicles on different grades of roads within the congestion range, calculate the congestion delay index, and divide the congestion grades. The congestion grades of different grades of roads and different types of vehicles within the congestion range are shown in Table 3.

[0067] Table 3 The average travel speed and congestion mileage of major road congestion within the traffic congestion range of Zhengzhou

[0068]

[0069] 2. Calculate the value of each parameter in the model based on on-site survey data, relevant data from the statistical yearbook, etc.

[0070] (1) Calculate the unit hour time value ω of the group of cars, medium cars, and large cars j . It can be calculated that the per capit...

Abstract

The invention discloses an urban traffic congestion cost estimation method based on road grades and vehicle types. The method comprises the steps of collecting main macro and micro data related to urban traffic congestion; establishing an urban traffic congestion extra cost model, wherein the urban traffic congestion extra costs comprise the congestion extra time cost, the congestion extra fuel cost and the congestion extra environment pollution cost, all of which are worked out based on classification of the road grades and classification of vehicle types; estimating the value of the urban traffic congestion extra costs. According to the method, key factors influencing operation of a traffic system are comprehensively mastered through macro qualitative analysis and micro quantitative analysis. Thus, the method has the advantages of scientificity, comprehensiveness, universality, strong operability and the like and is of great practical significance for comprehensively learning urban traffic congestion conditions and researching congestion management strategies.

Description

technical field [0001] The invention relates to the fields of urban road systems, vehicle systems, and traffic congestion control, and in particular to a method for estimating urban traffic congestion costs based on road grades and vehicle types. Background technique [0002] The rapid development of urban motorization has brought a series of problems to urban traffic, and the losses caused by traffic congestion in cities are increasing year by year. Scholars at home and abroad have put forward a large number of congestion management theories and practical methods. Among them, the loss caused by traffic congestion has become a research hotspot. [0003] Congestion cost quantification research will eventually implement the fundamental purpose of congestion control measures. Congestion cost quantification is related to factors such as roads, vehicles, people, and resources. The congestion cost estimation method is a comprehensive analysis method based on economics and mathem...
