Traffic reachability index optimization method applied to territorial space overall planning

Abstract

The invention discloses a traffic reachability index optimization method applied to territorial space overall planning. The method comprises the following steps: S1, establishing a traffic reachability index system; and S2, constructing a traffic reachability deepening model, comprising S2.1, selecting a traffic reachability input index and a traffic reachability initial model, and measuring and calculating the reachability, S2.2, grading by a natural discontinuity point grading method, and S2.3, carrying out weighted calculation on the reachability of the region. According to the method, a traffic reachability deepening analysis model and a new reachability index system are established, and a quantitative decision reference or a scheme evaluation result is provided for land space planning and land utilization planning, urban overall planning and main functional area planning included in the land space planning. The method can be used as an intermediary index for cooperation of traffic planning and territorial space planning.

Description

technical field [0001] The invention belongs to the technical field of traffic accessibility evaluation, and in particular relates to a traffic accessibility index optimization method applied to the overall planning of land space. Background technique [0002] The role of traffic accessibility assessment [0003] In the field of transportation planning, transportation accessibility mainly refers to the degree of convenience for people in a certain area to use a certain mode of transportation to obtain opportunities such as employment, school, and shopping. On the one hand, traffic accessibility reflects the possibility of travelers occupying traffic resources under different land use conditions; on the other hand, traffic accessibility can reflect the opportunities of travelers to participate in specific activities or use public facilities. [0004] In the "multi-plan integration" national land space planning system, transportation planning needs to be coordinated with land...

[0014] 2. Opportunity cumulative model: The determination of the travel cost threshold is too subjective, and it is assumed that all opportunities have the same attractiveness to travel individuals, without considering the differences in the attractiveness of different opportunities to different groups of people;

[0015] 3. Spatial interaction model: When the distance is small, the calculation of accessibility is extremely sensitive; the model cannot calculate the potential of the starting point area, and does not consider the land use factors of the starting point area itself;

[0017] The above-mentioned accessibility models all have limitations and cannot be directly used in traffic planning or land space planning. Some models can only evaluate traffic factors or land use factors alone, and further improvement is needed
