Traffic assignment method based on traveler budget constraint

Abstract

The invention provides a traffic assignment method based on a traveler budget constraint. The traffic assignment method comprises the following steps: S1, acquiring network structure data and relevant parameter information of a target traffic network, and building an abstract traffic network; S2, determining a traffic demand of the target traffic network by using the abstract traffic network; S3, building a budget constraint model of the target traffic network according to the traffic demand; S4, building a traffic assignment model according to the budget constraint model; S5, solving and calculating the traffic assignment model to obtain an assignment result of the target traffic network. By adopting the traffic assignment method based on the traveler budget constraint provided by the invention, a more accurate quantified performance rating result is provided for the reconstruction of a traffic and transport network, a sufficient basis can be provided for congestion pricing, and other traveling services such as traveling plans can be provided for a user through a path traveling time index output by the model.

Description

technical field [0001] The invention relates to the field of road traffic management, in particular to a traffic allocation method based on travelers' budget constraints. Background technique [0002] Traffic congestion is a serious problem that accompanies the process of urbanization, and has a significant negative impact on the national economy, residents' sense of well-being, and the environment. Faced with the increasingly serious traffic congestion problem, some big cities are preparing to impose congestion charges, using economic means to limit the traffic density of urban roads during peak hours, and reduce the occurrence of traffic accidents and the environment through the resulting reduction in traffic volume. pollution and energy consumption, and improve the operational efficiency of the entire urban traffic. [0003] Existing traffic allocation schemes need to know the set of all routes that know the road, which will consume a lot of time and storage space in pra...

AI Technical Summary

Problems solved by technology

[0003] Existing traffic allocation schemes need to know the set of all routes that know the road, which will consume a lot of time and storage space in practice, and the heterogeneity of users is reflected in many aspects. Different groups of people travel, due to their travel purposes, travelers and machines Different types of motor vehicles have various budget constraints, which have not been considered in the existing route allocation, so it cannot reflect the impact on the balance of the transportation network due to the different budget constraints of different groups of people, thus affecting the planning of the road network. Prediction of traffic flow and decision-making of road network planning scheme
