Traffic assignment method based on traveler budget constraint

Abstract

The present invention provides a traffic allocation method based on the traveler's budget limit, including steps: S1: Obtain network structure data and related parameter information of a target traffic network, and establish an abstract traffic network; S2: Use the abstract traffic network to determine Traffic demand of the target traffic network; S3: Establish a budget constraint model of the target traffic network according to the traffic demand; S4: Establish a traffic allocation model according to the budget constraint model; S5: For the traffic The allocation model is solved and calculated to obtain the allocation result of the target traffic network. A traffic allocation method based on the traveler's budget limit in the present invention provides more accurate quantified performance evaluation results for the reconstruction of the transportation network, not only can provide a sufficient basis for congestion charging, but also the path travel time index output by the model Other travel services such as travel planning may also be provided to the user.

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...

[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 b
