A Dynamic Model-Based Evaluation Method for the Carrying Capacity of Traffic Facilities Oriented to the City

Abstract

The present invention provides a method for assessing the carrying capacity of traffic facilities based on a dynamic model for the overall situation of the city. Based on the dynamic model allocation method, with the help of the four-stage traffic model of land use, the traffic demand is calculated by analyzing the population employment scale under the planned land use. The total amount and the spatial distribution of traffic trips, considering the accessibility and service characteristics of various transportation facilities such as urban roads, public transportation, and rails, calculate the supply capacity, and scientifically evaluate the carrying capacity of transportation facilities; the evaluation method of the present invention adopts "from the whole to the local The organization method of "multiple land feedback" can not only evaluate the coordination degree of transportation facilities and land use at the overall level of the city, but also put forward optimization suggestions at the local level. The evaluation method of the present invention can be directly applied to land space planning, urban general planning, land development intensity demarcation, etc., to guide the reasonable scale and layout of land use, and realize the matching of land development scale and traffic facility capacity.

Description

technical field [0001] The invention relates to the field of integrated planning of traffic and land, in particular to a method for evaluating the carrying capacity of traffic facilities based on a dynamic model for the overall city. Background technique [0002] In real life, traffic congestion such as heavy traffic flow on urban roads during peak hours, long queuing delays, crowded railcars, and peak traffic restrictions at stations frequently occur. too high. Therefore, it is necessary to carry out the evaluation of the carrying capacity of transportation facilities in the land use planning stage, which will not only help improve the efficiency of land use, but also reduce the probability of congestion after the implementation of the plan. [0003] With the worsening of traffic problems, more and more attention has been paid to the evaluation of the carrying capacity of transportation facilities. There have been many research results on the evaluation methods of carrying...

AI Technical Summary

Problems solved by technology

[0004] 1. The evaluation methods for the carrying capacity of transportation facilities are concentrated in local areas, and the comprehensive evaluation methods at the city level are not yet mature

[0005] 2. The evaluation method of the carrying capacity of transportation facilities focuses on a single transportation system, such as the road traffic system, and lacks an evaluation algorithm for the carrying capacity of facilities in an integrated transportation system

[0006] 3. The evaluation method of the carrying capacity of transportation facilities is generally based on the static traffic capacity summary method, the calculation accuracy is low, and the internal relationship between the relationship between land and transportation is not revealed enough
