OBJECTIVES We sought to determine the association between urban sprawl and traffic fatalities. METHODS We created a sprawl index by applying principal components analysis to data for 448 US counties in the largest 101 metropolitan areas. Regression analysis was used to determine associations between the index and traffic fatalities. RESULTS For every 1% increase in the index (i.e., more com...

This study investigates the influence of lifestyle of individuals on their walking behavior and their expectations from pedestrian infrastructure. This project is part of a series of studies looking into region specific characteristics of pedestrian behavior. Part of the challenge during this project has been to identify attributes that relate to lifestyle of individuals and collection of relev...

This paper introduces active pedestrian protection system (APPS) project, which was fulfilled during last three years (Nov. 2006 – Oct. 2009) and supported by ministry of knowledge economy (MKE) of Korean government, and then summarizes its achievements. To reduce the number and severity of vehicle-pedestrian accident by active safety vehicle (ASV), false alarm rate should be minimized. For thi...

Crash prediction models are used to estimate the number of crashes using a set of explanatory variables. The highway safety community has used modeling techniques to predict vehicle-to-vehicle crashes for decades. Specifically, generalized linear models (GLMs) are commonly used because they can model non-linear count data such as motor vehicle crashes. Regression models such as the Poisson, Zer...

BACKGROUND Pedestrian and bicyclist injury is an important public health issue. The retail environment, particularly the presence of alcohol outlets, may contribute the the risk of pedestrian or bicyclist injury, but this association is poorly understood. METHODS This study quantifies the spatial risk of alcohol-related pedestrian injury in New York City at the census tract level over a recen...

Wind comfort and wind safety for pedestrians are important requirements in urban areas. Many city authorities request studies of pedestrian wind comfort and wind safety for new buildings and new urban areas. These studies involve combining statistical meteorological data, aerodynamic information and criteria for wind comfort and wind safety. Detailed aerodynamic information can be obtained usin...

Christchurch City Council commissioned an investigation into ways of improving pedestrian level of service (LOS) at traffic signals in the central city. In 2009, Gehl Architects prepared a study entitled Public Space Public Life (2010) that considered how people use public spaces and streets in central Christchurch. This precedent study resulted in Christchurch City Council’s adoption of A City...

Safety is the most important to the mobile robots that coexist with human. There are many studies that investigate obstacle detection and collision avoidance by predicting obstacles’ trajectories several seconds into the future using mounted sensors such as cameras and laser range finder (LRF) for the safe behavior control of robots. In environments such as crossing roads where blind areas occu...

Measurement of pedestrian traffic in public areas (e.g., stations, airports, shopping malls or complex buildings) provides valuable information. For safety management, congestions can be detected to prevent accidents in their early stage by monitoring the pedestrian traffic continuously. Knowing the number of people working in a large building may help to when designing evacuation plans. For ma...

Pedestrian data collection is critical for the planning and design of pedestrian facilities. Most pedestrian data collection efforts involve field observations or observer-based video analysis. These manual observations are time consuming, limited in coverage, resource intensive and error prone. Automated video analysis which involves the use of computer vision techniques can overcome many of t...
