Abstract

The invention provides an urban global traffic facility bearing capacity evaluation method based on a dynamic model. A dynamic model allocation method is used as a basis; by means of a traffic four-stage model of land utilization, the population employment scale under land utilization is analyzed and planned, the total traffic demand and traffic travel space distribution are calculated, the accessibility and service characteristics of various traffic facilities such as urban roads, buses and rails are considered to calculate the supply capacity, and the traffic facility bearing capacity is scientifically evaluated; according to the evaluation method, an organization mode of 'multiple feedback of traffic land from the whole to the part' is adopted, the coordination degree of traffic facilities and land utilization on the whole level of the whole city can be evaluated, and optimization suggestions can be provided on the local level. The evaluation method can be directly applied to territorial space planning, urban general regulation, land development intensity demarcation and the like, guides reasonable scale and layout of land utilization, and realizes matching of the 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...
