Abstract
Walking is a widely adopted mode of urban transportation, and pedestrians, being
vulnerable road users, require particular attention while crossing road. The study of
pedestrian road-crossing behavior is a crucial aspect in the establishment of road crossing
facilities. Its importance comes from the huge challenges provided by the interaction of
pedestrians and vehicles during crossing scenarios. While previous studies have explored
pedestrian crossing behavior at midblock, the comprehensive examination of the potential
impacts of gap selection on pedestrian behavior at unsignalized crosswalks within
intersections remains relatively unexplored.
This study investigates the pedestrian gap selection behavior while crossing road at
crosswalk of unsignalized intersection using Binary logistic regression. From the numerical
finding it was found that gender, age, pedestrian carrying object in hand, group size,
vehicle’s type, crossing pattern, vehicle speed, pedestrian waiting time and pedestrian
crossing time influence on shorter gap selection. In this study, female and elderly people
prefer longer gap over shorter gap to cross the road safely. The odd of pedestrian choosing
longer gap over shorter gap increases as vehicle speed increases. Similarly, pedestrian who
do not carry any object in hand and who are alone also prefer shorter gap over longer one.
In case of type of vehicles, pedestrian preferred shorter gap over longer gap when vehicles
were 2-wheeler as compared to 4/6-wheeler. Similarly, pedestrian who follow In-to-In
crossing path (II) and In-to-Out Crossing (IO) over Out-to-In/Out Crossing (OI/O) have
likelihood of choosing longer gap in comparison to shorter gap. Therefore, planners can use
this knowledge to enhance pedestrian facilities, and encourage responsible crossing
practices.
