Embodiment Construction

[0032] The present invention will be further described below in conjunction with specific examples.

[0033] Such as figure 1 As shown, the method for calculating the mixed traffic carrying capacity of the urban road network described in this embodiment includes the following steps:

[0034] 1) Calculate the time and space consumption of motor vehicles on the urban road network for daily travel:

[0035] c v =s v ×T v =42.9×0.76=32.604(m 2 h / pcu)

[0036] Among them, c v is the average time and space consumption of a single motor vehicle per day, m 2 h / pcu;s v is the road area occupied by motor vehicles, in m 2 ; T v is the average daily travel time of motor vehicles on the road network, in hours.

[0037] 2) Calculate the time and space consumption of non-motorized vehicles in the urban road network for daily travel:

[0038] c n =s n ×T n =8.9×0.9=8.01(m 2 h / vehicle)

[0039] Among them, c n is the average time and space consumption of a single non-motorize...

Abstract

The invention discloses an urban road network hybrid traffic carrying capacity calculation method comprising the steps that 1) urban road network motor vehicle daily traveling time and space consumption is calculated; 2) urban road network non-motor vehicle daily traveling time and space consumption is calculated; 3) urban road network motor vehicle traffic time and space resource C1 is calculated; 4) urban road network non-motor vehicle traffic time and space resource C2 is calculated; and 5) urban road network hybrid traffic carrying capacity N is calculated. The basis is provided for planning and management of control of total urban motor vehicles and non-motor vehicles so that the urban road network hybrid traffic carrying capacity calculation method has practical popularization value.

Description

technical field [0001] The invention relates to the field of traffic planning and management, in particular to a method for calculating the mixed traffic carrying capacity of an urban road network. Background technique [0002] The mixed traffic carrying capacity of the urban road network refers to the maximum capacity that the urban road network can support under the conditions of external constraints such as resources and the environment, using traffic management technology and other conditions within a certain period of time, and satisfying a certain level of traffic service and efficiency. Total motorized and non-motorized vehicle trips. [0003] Since the internal road network of the city is dominated by motor vehicles, and the operation of motor vehicles is relatively standardized, it is easy for theoretical research and analysis. The current domestic research on urban road network carrying capacity or road network capacity focuses on motor vehicles. The commonly used...
