In India, over 25,000 pedestrian fatalities occur due to road crashes every year. While several studies have identified possible causative factors that contribute to these fatalities, little is known about how pedestrians perceive their surrounding environment. This study attempts to bridge this gap by analysing the pedestrian perception of the built environment and traffic-related aspects considering urban roads (arterial and sub-arterial). Fourteen parameters were selected to assess pedestrian perception, and four factors were derived through factor analysis. The obtained factor scores were then subjected to two-step cluster analysis to determine whether pedestrian perception is different for people from different socio-economic demographics with varying travel behaviour. Based on the results obtained from the descriptive analysis, the respondents were most satisfied with the 'quality of streetlights at sidewalks' and 'visibility/sight distances', while they were most dissatisfied with 'pedestrian volume at sidewalks' and 'lighting facilities at crossings'. From the cluster analysis, it can be summarized that female pedestrians walk less frequently than males and perceive a higher probability of collision or near-collision incidents against male pedestrians. The study findings can aid the policymakers in the assessment of the pedestrian perception of the existing road infrastructure and suggest improvements to ensure pedestrian safety.
在印度，每年有超过 25000 名行人因道路交通事故死亡。虽然有几项研究已经确定了可能导致这些死亡的因素，但对于行人如何感知周围环境却知之甚少。本研究试图通过分析城市道路（动脉和次动脉）中行人对建筑环境和交通相关方面的感知来填补这一空白。选择了 14 个参数来评估行人的感知，通过因子分析得出了 4 个因素。然后对获得的因子得分进行两步聚类分析，以确定具有不同出行行为的不同社会经济人口特征的人对行人感知是否存在差异。根据描述性分析的结果，受访者对“人行道上路灯的质量”和“可见度/视距”最满意，而对“人行道上的行人数量”和“交叉口的照明设施”最不满意。从聚类分析中可以总结出，女性行人比男性行人走得少，并且感知到与男性行人发生碰撞或险些碰撞的概率更高。研究结果可以帮助决策者评估现有道路基础设施的行人感知，并提出改进措施以确保行人安全。
