Application-oriented Implementation Effect Evaluation System of Pedestrian Reconstructing Plans and Case Analysis

Abstract

This paper develops the pedestrian evaluation system from two aspects which are implementation effect evaluation index system and evaluation method. Firstly, it analyzes the requirements of the evaluation index system of pedestrian reconstructing plans. On the basis, it establishes the implementation effect evaluation index system considering three aspects which are pedestrian facilities, transportation and safety. Then, it proposes the evaluation stages which are to make negative type indexes convert to positive type indexes, to make indexes being dimensionless, to calculate the weight for every index, and to calculate the comprehensive index value. In this paper, it studies the applicability of the different converted methods from negative type indexes to positive type indexes and non-dimensional methods considering the characteristic of the pedestrian evaluation indexes. And it proposes the two-level combined method for calculating weights on the basis of comparative analysis about three methods, which are the analytic hierarchy process (AHP) method, entropy method and information weight method. Finally, the paper applies the proposed evaluation system to calculate the comprehensive index values before and after pedestrian reconstructing plans along 3rd Round-the-Corridor in Danling Street in Zhongguancun West Area. The comprehensive value after reconstruction is 0.739 based on the two-level combined evaluation method, which is higher than the value before reconstruction. The result shows that it is useful of pedestrian reconstructing plans to improve the service level of the sidewalk.
