内容記述 Pedestrian safety is one of the most challenging issues in road networks. Understanding how pedestrians
maneuver across an intersection is the key to applying countermeasures against traffic crashes. It is known that
the behaviors of pedestrians at signalized crosswalks are significantly different from those in ordinary walking
spaces, and they are highly influenced by signal indication, potential conflicts with vehicles, and intersection
geometries. One of the most important characteristics of pedestrian behavior at crosswalks is the possible sudden
speed change while crossing. Such sudden behavioral change may not be expected by conflicting vehicles, which
may lead to hazardous situations. This study aims to quantitatively model the sudden speed changes of pedestrians
as they cross signalized crosswalks under uncongested conditions. Pedestrian speed profiles are collected
from empirical data and speed change events are extracted assuming that the speed profiles are stepwise
functions. The occurrence of speed change events is described by a discrete choice model as a function of the
necessary walking speed to complete crossing before the red interval ends, current speed, and the presence of
turning vehicles in the conflict area. The amount of speed change before and after the event is modeled using
regression analysis. A Monte Carlo simulation is applied for the entire speed profile of the pedestrians. The
results show that the model can represent the pedestrian travel time distribution more accurately than the
constant speed model.
