Pedestrian temporal and spatial gap acceptance at mid-block street crossing in developing world

Area of Science:

• Transportation Engineering
• Traffic Safety
• Human Factors in Transportation

Background:

• Uncontrolled midblock pedestrian crossings in India present complex safety challenges due to unpredictable pedestrian behavior.
• Vehicles often fail to yield to pedestrians, necessitating pedestrians to assess gap safety independently.

Purpose of the Study:

• To investigate pedestrian temporal and spatial gap acceptance at uncontrolled midblock street crossings in urban India.
• To develop models for understanding pedestrian crossing decisions in complex traffic environments.

Main Methods:

• Collected video data from two midblock pedestrian crossings, analyzing 1107 pedestrian gaps.
• Utilized binary logit analysis to develop six utility models for temporal and spatial gap acceptance.
• Observed rolling gap acceptance behavior for multi-lane crossings.

Main Results:

• 50th percentile temporal and spatial gaps were 4.1–4.8s and 67–79m; 85th percentile gaps were 5–5.8s and 82–95m.
• These accepted gaps are smaller than those reported in developed countries.
• Conflicting vehicle speed and vehicle type significantly affected gap acceptance decisions.

Conclusions:

• Findings provide crucial data on pedestrian gap acceptance in developing countries.
• Insights can inform safety and performance evaluations of similar crossings globally.
• Highlights the need for context-specific traffic safety strategies.
