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.
