Quantifying the effects of crosswalk length and signal timing on pedestrian walking speed is an important requirement for providing a rational safety assessment and improving existing operational policies at signalized intersections. This study investigates the effects of pedestrian green time (PG), crosswalk length and pedestrian crossing direction on pedestrian walking speed at signalized cro...

Pedestrian detection is one of the most important research contents of road safety. The crucial idea behind such pedestrian safety systems is to protect the driver and pedestrian from any accident. In this paper, a pedestrian feature extraction based on applied log-Gabor filters is presented. The resulting filtered images show desirable segmentation performance which allows support vector machi...

One of the objectives of understanding pedestrian behavior is to predict the effect of proposed changes in the design or evaluation of pedestrian facilities. We want to know the impact to the user of the facilities (i.e. pedestrian), as the design of the facilities change. That impact was traditionally evaluated by level of service standards (LOS). Another design criterion to measure the impact...

Most studies of pedestrian injuries focus on reducing traumatic injuries due to the primary impact between the vehicle and the pedestrian. However, based on the Pedestrian Crash Data Study (PCDS), some researchers concluded that one of the leading causes of head injury for pedestrian crashes can be attributed to the secondary impact, defined as the impact of the pedestrian with the ground after...

There is now increasing emphasis on managing the urban transport for the benefit of all road users, particularly on the promotion of walking and cycling as more environmentally friendly modes of transport. Dynamic traffic signal controls in respond to pedestrian demand have been developed which give the flexibility and control to the network controllers to manage pedestrian and vehicle interact...

Pedestrian safety is a major concern due to the vulnerability of pedestrians versus other traffic, especially in urban environment. The fatalities and injuries suffered in pedestrian collisions often intensify the perceived severity of these accidents. The problem is particularly significant for transit bus operations because their operations encounter pedestrian traffic regularly in their rout...

Pedestrian protection project is presently the key aim in the fields of traffic safety and vehicle passive safety, which is attached to great importance by numerous researchers at home and abroad. Based on PC-Crash program for simulation and reconstruction of road accident and in-line MADYMO program for multi-body system dynamics analysis, the kinematics law and characteristics of pedestrian in...

OBJECTIVES Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: 1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and...

Human detection is a challenging classification problem which has many potential applications including monitoring pedestrian junctions, young children in school and old people in hospitals, and several security, surveillance and civilian applications. Various approaches have been proposed to solve this problem. We have studied and implemented a scheme using Histogram of Oriented Gradients (HOG...
