Research on Street Walkability Evaluation Considering Travel Health

Walking is a low-carbon lifestyle with obvious ecological, social, economic, and health benefits. Good walkability helps to enhance street vitality and promote more green travel behaviors. Walkability is an important indicator of pedestrian-friendliness and an important part of healthy urban planning. This study incorporates the pollutant exposure level into the walkability evaluation system, which helps assess street walkability from the perspective of travel health. Taking urban streets as the research object, the basic data was collected based on field survey, including the facilities’ convenience around the street, intersection density, street length, and pollutant exposure. According to the dataset, street walkability index was developed, and case study was conducted to quantify streets walkability. The results demonstrated that in the peak period, street walkability was significantly different before and after considering pollutant exposure. The research results could provide support for deployment of street facilities and healthy travel path planning for pedestrians.
