Evaluation and Diagnosis for the Pedestrian Quality of Service in Urban Riverfront Streets

Leisure walking can improve the physical and mental health of urban people. Especially, riverfront streets have a comfortable blue space that can bring higher pedestrian benefits. Improving the pedestrian quality of service (PQOS) of riverfront streets is crucial. However, the needs of citizens for walking and daily activities are rarely considered in the riverfront streets. This paper established the evaluation system for PQOS of riverfront streets from five aspects of accessibility, attractiveness, comfort, safety and pleasure, and realized the collection and calculation of indicators through space syntax, semantic segmentation and other methods. Taking Jilin Riverfront Streets as examples, the PQOS was evaluated. Through the establishment of the coordinate system, the streets were divided into four categories: Advantage, Maintain, Opportunity and Improvement streets. The renewal strategies were proposed. The results showed that the PQOS have great room for improvement. The natural openness ratio and blue visual index of the improvement streets need to be enhanced. Most opportunity streets were located in the residential, industrial and biophilic districts. The number and types of service facilities need to be increased. The evaluation method can assist the designers to update the PQOS of riverfront streets, and provide data support for that.
