Abstract
Enhancing the walkability of urban streets is an effective means to improve public health, alleviate traffic congestion, and enhance the living environment. In China, the government has actively encouraged green travel and promoted improvements in the walk system. The walkability of the built environment is affected by many factors. In addition to the configuration of daily life facilities, street greening can have significant effects on walkability. To explore the rationality of street life facilities and understand the impact of the natural attributes of the block space (street-level greening) on the quality of the walking environment, we evaluated the walkability of Zhongshan Road in Qingdao, China and optimized the algorithm of the walk score. In this study, we selected residential areas as the starting point and modified the weight coefficients for facilities to evaluate the walkability of streets. Traditional research methods were combined with street view image capture, and the rate of the attenuation factor was used for the new optimization algorithm. We discussed the rationality of street life facilities and increased the green vision rate using a correction index. By comparing changes in walkability before and after joining, we analyzed the necessity of including new indicators. The results show that the average walking index of Zhongshan Road is 79.74, and the overall performance is good, showing a high trend in the west and a low trend in the east, and a high trend in the south and a low trend in the north. According to the general walking index, western stations and southern coastal areas have higher scores, and living facilities are well equipped; old northern and eastern residential areas have lower scores. Among them, the average weight of bookstores is 0.74, and the average weight of parks is 0.69. To meet residents’ needs for daily leisure activities, adding bookstores or similar facilities in community parks would be necessary to improve daily facilities and services. The average green viewing rate of Zhongshan Road is 20.48%, which is lower than the best visual perception value of 25.00%. Comparing the walking index changes before and after adding the green viewing rate, the high-scoring area shifted from the west to the south, and the west walking index has the most significant decline. Street greening has a certain impact on the quality of the walking environment. The results and conclusions of this study can be used as a reference in developing street walkability indicators and further improving the evaluation system.
Highlights
The main purpose of this study is to measure the walkability of Zhongshan Road through the walk score and evaluate the rationality of living facility allocation at the walking level
The results of the general walking index analysis are shown in Figure street performance performance is good, showing showing aa high west and in the the east, east, street is good, high trend trend in in the the west and aa low low trend trend in and a high trend in the south and a low trend in the north
The results show that the average walking indexes for Ankangli, Pingkang Wuli, Sanjiangli, and Pinghewuli were less than 70.00
Summary
In the World Health Organization’s global public health report released in 2017, 27.5%. Walking is a relatively relaxed and unrestricted sports activity [2], and most people can complete it in the streets and open spaces within urban communities. Travel Action Plan” in 2019, giving walking the right to allocate and balance road traffic resources to build a safe, continuous, and comfortable urban pedestrian road system. It is important for urban planners to understand the construction of walkable places. Existing research has shown that factors at different levels, from the built environment, street accessibility, and rationality of living facilities, can affect
