Greenway Walkability Evaluation and Obstacle Factor Diagnosis Based on the AHP
With the improvement of living standards and the change in people's life philosophies,urban and rural residents have an increasingly strong demand for urban non-motorized traffic spaces,which are typically represented by greenways.Evaluations of walkability can help assess the effectiveness of greenway construction,implement targeted improvements,and thereby promote the development of Park City.Taking the five sections of the greenway of Luopu Park in Luoyang as the research object,the article formulated an evaluation system covering 4 first-level indicators including"convenience,functionality,comfort and attractiveness",as well as 18 second-level indicators such as"time consumption for arriving".Adopting the Analytic Hierarchy Process(AHP),the article calculated the comprehensive evaluation index.At the same time,the calculation of obstacle degree was introduced to diagnose the obstacle factors of greenways.The results showed that the pedestrian-friendliness of the Luopu Park green way was generally good.The comprehensive evaluation grade of No.2 was level I,and the others were level Ⅱ.The biggest obstacle factors of each section were"road surface integrity,rest(rain shelter)facilities,user satisfaction with walking experience,and road surface integrity",and"time consumption for arrival".Through the evaluation,the effectiveness and existing issues of Luopu Park greenway regarding walkability were identified which could be beneficial for improving the walkability of each section during the construction of Park City in Luoyang.
