Embodiment Construction

[0056] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0057] Such as figure 1 As shown, the cascading failure-based method for determining the range of influence of airport landside road traffic congestion provided by the present invention includes the following steps carried out in order:

[0058] Step 1) Construct the airport landside road traffic network and the travel network of travelers, and determine the capacity C of each directional road section a in the airport landside road traffic network a , and set the OD traffic of each OD (Orign and Destination, starting and ending point) pair in the travel network;

[0059] Combined with the actual road structure on the land side of an airport, construct the road traffic network on the land side of the airport, such as figure 2 shown. Road intersections in the landside road traffic network of the airport are represented as nodes, and directe...

Abstract

A cascading failure-based method for determining the impact range of airport landside road traffic congestion. It includes constructing the landside road traffic network of the airport and the travel network of travelers, setting the OD flow of each OD pair in the travel network; initially allocating the OD traffic of each OD pair to the airport landside road traffic network, and determining The road saturation of each directional road section; obtain the road saturation of each directional road section after cascading failure; determine the influence range of traffic congestion in the airport landside road traffic network and other steps. Effects of the present invention: the method is simple, and the influence range of congestion propagation in the airport landside road traffic network can be determined. When facing the airport landside road traffic congestion, it is convenient to take relevant traffic control measures at the first time to ensure the airport landside. Efficiency of the road transport system.

Description

technical field [0001] The invention belongs to the technical field of traffic network control, and in particular relates to a method for determining the impact range of airport landside road traffic congestion based on cascading failures. Background technique [0002] The landside road traffic network of the airport is the key to connecting the airside of the airport with the urban area. With the increase of civil aviation passenger turnover and the number of social vehicles, the collection and distribution transportation demand of the landside road traffic system of the airport is growing rapidly, and its traffic congestion has become a problem. An important factor affecting the continuous improvement of civil aviation service quality and collaborative operation efficiency. Clarifying the impact range of traffic congestion in the airport landside road traffic network is the basis for formulating targeted airport landside road traffic control measures. [0003] In terms of...
