摘要： 开展面向街道的步行与骑行环境评估对发展绿色交通具有重要意义。建立针对便捷、安全和 舒适三个维度的步行与骑行环境指标体系，进而构建街道尺度的步行指数和骑行指数。以天津市为 例，对中心城区1 569 km道路开展实证研究，并结合7 个住宅小区的居民出行调查数据进行相关性 分析。研究发现：天津市中心城区步行环境整体优于骑行环境；街道的步行指数和骑行指数均呈现 随城市不同发展阶段由中心向外围递减的趋势，其中便捷性指数递减趋势最为明显，安全性指数次 之。步行指数与小区居民步行出行分担率显著正相关，而骑行指数与自行车出行分担率相关性不显 著。最后，对天津市步行和骑行环境改善提出政策建议。

Abstract： It is necessary to evaluate street walkability and bikeablity for green transportation development. This paper proposes an evaluation system for walking and cycling environment based on the convenience, safety and comfortableness and develops the street walkability and bikeability indexes. Taking Tianjin as an example, the paper evaluates the 1,569 kilometer roadways in the urban central district and conducts correlation analysis with household travel survey data of seven residential communities. The results show that walking environment in Tianjin central district is generally better than cycling environment. Walkability index and bikeability index decrease from the central district to suburban district as the city going through different development stages. The degree of convenience declines the most followed by the safety. Walkability index has a positive and significant correlation with residents' travel mode share of walking, while bikeability index has no significant impact on travel by bike. Finally, the paper provides suggestions on how to improve walking and cycling environment in Tianjin.
