老年人休闲步行环境评价是规划干预步行环境建设的重要方法.运用叙述性偏好法和离散选择模型,构建老年人休闲步行环境评价指标体系,并获得其相应的权重值.以上海鞍山新村为例,评价案例地区现状步行环境的老年友好程度.研究发现,叙述性偏好法是行之有效的评价老年休闲步行环境质量的方法;老年步行者对机动车流量大小较为敏感,其次是遮荫情况、人流量大小、人行道界面情况和有效通行宽度.定量评价老年休闲步行环境的方法,为提升步行环境的老年友好程度提供了一种行为视角的新思路.%Walking environment is an important issue in public health and urban planning. The paper aims to contribute to the methods of evaluating and improving walking environment for the elderly by exploring the underlying mechanisms of pedestrians' route choice behavior in stroll activities. Stated preference (SP) method is used to investigate how walking environment attributes influence pedestrian walking behavior. Respondents were presented with hypothetical routes for choice, generated with SP. The behavioral data were estimated using Discrete Choice Models (DCM) to derive the impact of each attribute on the utility of a route. The results show that SP method is effective to evaluate the elderly walking environment, and the elderly is sensitive to the traffic volume, followed by shading, pedestrian volume, facade and effective width. The evaluation of the elderly walking environment provides a new way to improve environment for specific group.
