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...

Vulnerable road users have steadily attracted increased importance in transport and planning. The behaviour of pedestrian movements (especially in the areas off but adjacent to roads) requires improved tools to address the issues now being raised. Such behaviour and interactions can now be modelled by using a combination of massively parallel processes simulating individual pedestrians, and a s...

This paper addresses future pedestrian accident scenarios involving next decade of small electric vehicles (SEVs) employed primarily in urban areas in 2025. The methodology used to predict the most relevant accident scenarios in 2025, in terms of speeds, impact locations, vehicle designs and inner-city boundaries, includes four main steps and as an example, the first three steps are shown for p...

pedestrian streets as one type of urban public spaces have an important role in improving the quality of urban life. in iran, planning and designing of pedestrian streets is in its primary steps. in spite of starting this approach in iran, and designing several pedestrian streets, there are still not organized studies about quality assessment of pedestrian streets. as a result, the strength and...

To date there are no clear or uniform standards for a method to measure pedestrian crash rates and compare it against a statewide average. In this paper, a novel methodology to measure pedestrian crash rates along roadways and intersections were quantified. The main objective is to identify critical pedestrian crash locations that are operating above its corresponding statewide average. It was ...

This article describes relationships between selected physical characteristics of urban streets and pedestrianlevel heat. It also identifies conditions that are particularly vulnerable to the summer heat. Field measurements of ambient temperatures 1 m above the ground were collected over sidewalks, green spaces, and parking lots in high density commercial and residential areas. Panel autoregres...

Pedestrian detection is an important application in computer vision. Currently, most pedestrian detection methods focus on learning one or multiple fixed models. These algorithms rely heavily on training data and do not perform well in handling various pedestrian deformations. To address this problem, we analyze the cause of pedestrian deformation and propose a method to adaptively describe the...

Quantifying effects of crosswalk length and signal timing on pedestrians’ presence position and timing is an important requirement for evaluating the probability of conflict. It can be utilized to provide a rational safety assessment and improve existing operational policies at signalized intersections. This study investigates the effects of crosswalk length and pedestrian green time on the spa...

The study investigates the influence of road intersections on pedestrian accessibility in urban-rural fringe areas. An evaluation method to support planners and decision makers in the classification of crossing areas according to their effect on walking and in the prioritization of improvement interventions is proposed. In these peripheral parts of towns, pedestrians are almost ignored and peop...

Robust, fast object detection systems are critical to the success of next-generation automotive vision systems. An important criteria is that the detection system be easily configurable to a new domain or environment. In this paper, we present work on a general object detection system that can be trained to detect different types of objects; we will focus on the task of pedestrian detection. Th...
