Abstract

The invention discloses an urban road travel time reliability evaluation method considering cognitive uncertainty, and the method comprises the steps: carrying out the analysis of a plurality of factors affecting the reliability of road travel time through an analytic hierarchy process, selecting a main factor as an evaluation index, determining a target layer, a factor layer, an index layer and a scheme layer, and building an evaluation index system; based on the uncertainty theory, determining the weight of each factor in the factor layer, the weight of each index of the index layer under a certain factor and the weight of each scheme of the scheme layer under a certain index layer; and carrying out weighted analysis on the weights of all the schemes in the scheme layers obtained by all the indexes corresponding to all the factors, and obtaining the optimal scheme in all the schemes according to a given scoring standard. According to the method, objective factors of roads and subjective factors of cognitive uncertainty of travelers are fully considered from the aspect of analytic hierarchy process, and more accurate evaluation of the reliability of the traffic system is provided.

Description

technical field [0001] The invention relates to the technical field of traffic management, and more specifically relates to a method for evaluating the reliability of urban road travel time considering cognitive uncertainty. Background technique [0002] With the continuous advancement of the urbanization process, the urban transportation network, as an important infrastructure for urban activities, is also under increasing pressure, especially for ground road traffic, where traffic congestion has become a "chronic disease" in many cities. The increasing maturity and application of technologies such as artificial intelligence, cyber-physical systems, big data, and cloud computing, and their integration with the transportation industry will surely promote the upgrading of urban transportation network technology, and smart road network systems will become the focus of future development. The basis of the smart road network system is the urban traffic road network. In order to ...
