基于行为偏好的休闲步行环境改善研究

RESEARCH ON IMPROVEMENT OF RECREATIONAL WALKING ENVIRONMENT BASED ON BEHAVIOR PREFERENCE

运用叙述性偏好法调查休闲步行环境选择行为,在此基础上构建离散选择模型,量化研究休闲步行者对于步行环境的偏好机制,辨识各关注要素的影响程度。研究发现,休闲步行者最关注的步行环境要素为机动车流量大小、遮荫情况和人行道有效宽度。选择上海市杨浦区鞍山新村地区作为实际案例,应用休闲步行环境偏好研究结论,评价现状步行环境,量化具体改造措施的实施效果,为步行环境改善方法的研究提供一种行为视角的新思路。

This paper uses the Stated Preference method to investigate the choice behavior of recreational walking environment, based on which a Discrete Choice Model to quantify the preference mechanism for walking environment by recreational walkers and to define the influence degrees of various related elements. Research results reveal that traffic volume, shade and pavement width are the main factors influencing pedestrian＇s route choice behavior. Based on the model, Anshan New Area of Yangpu District, Shanghai, has been taken as an example to evaluate the existing conditions of walking environment, and quantify the effectiveness of specific improvement measure with the utility maximum principle.
