Track station radiation area walking accessibility evaluation method based on micro area

Abstract

The invention provides a track station radiation area walking accessibility evaluation method based on a micro area. The method comprises the following steps: firstly, carrying out micro-region division on land in a rail station radiation region according to different land utilization properties; then, comprehensively considering factors such as road network distribution conditions, micro-area land utilization conditions and micro-area building plot ratios; determining comprehensive walking time, a comprehensive detour coefficient, a comprehensive spatial linear distance and footpath node density for evaluating the walking accessibility of the rail station; and finally, quantitatively evaluating the multiple rail stations by utilizing the TOPSIS model, wherein the weight of each index in the TOPSIS model is determined through an entropy weight method. The concept of the micro-area is fused into calculation of factors such as walking time, a detour coefficient and a spatial linear distance, so that the evaluation result is finer and more accurate.

Description

technical field [0001] The invention relates to a walking accessibility evaluation method of a radiation area of ​​a rail station, in particular to a method for evaluating the walking accessibility of a radiation area of ​​a rail station based on micro-zones. Background technique [0002] With the advantages of fast, punctual, safe, less pollution, large transport volume, high transport efficiency, and getting rid of traffic jams and accidents, rail transit has gradually become the most important means of transport in major cities in the world, and is relieving urban traffic bottlenecks. It has played a role that cannot be ignored in alleviating the contradiction of urban land use, optimizing the urban traffic structure and promoting sustainable economic and social development. From the perspective of the entire rail transit commuter travel itinerary, passengers not only care about the length of travel time in the car, but also care about the last mile of the rail station, t...

Problems solved by technology

However, the above methods all have some common problems: the calculation of the evaluation factors is not accurate enough, which affects the validity and reliability of the evaluation results

The reason: the statistics of walking time do not take into account the waiting and running time of elevators in buildings with high floor area ratios; the statistics of population density do not reflect the differences in the nature of different land uses. Commercial residential and low floor area ratio industrial land), the walking time of passengers in high floor area ratio blocks should be paid attention to, but the operation of averaging the population density of all land uses cannot make walking accessibility reflect the impact of high population agglomeration The slope the block should have

If the land around the rail station can be divided into micro-areas according to the nature of the land use, and the influence of the land use properties of the micro-area, the building volume ratio of the micro-area and other attributes are considered in the calculation of factors such as walking time, and the comprehensive walking time and other factor indicators are obtained, then Incorporating walking accessibility into the evaluation is expected to improve the accuracy of walking accessibility evaluation in the radiation area of ​​the orbital station, but the existing research and application have not proposed such a fine method
