Pedestrian safety at urban mid-block crossings
… Most of these crashes are likely to result in pedestrian severe injuries or fatalities, especially when crash impact speeds are high. Despite pedestrian-orientated designs being constructed around cities, the risk exposure for pedestrian crashes continues to remain a challenge for road safety …

Nationwide Pedestrian Safety Analysis Using Crash and Survey Data
Pedestrian safety is studied using two approaches: injury severity modeling using NHTSA’s Crash Report Sampling System crash data and administering a nationwide survey on roadway safety topics. The crash data models identified seven significant independent variables which relate to severe …

Virtual street-crossing performance in persons with multiple sclerosis: Implications for pedestrian safety
… investigation was to examine the feasibility and safety of assessing street crossing performance in people with MS, and to identify differences in street crossing performance between people with MS and non-MS controls. We further examined the relationship between street crossing performance and …

Investigating pedestrian safety solutions on rural high-order roads. Case-study: R71 Polokwane
South Africa's pedestrian accident rate is one of the highest in the world. The percentage of pedestrian accidents to total road accidents is approximately 33% (RTMC, 2011) far greater than the world average of 22% (World Health Organisation, 2013). The problem is more acute in rural areas where 1 …

Pedestrian Safety and Level of Service at Uncontrolled Crosswalks - Advanced Data to Enhance Evaluations
Pedestrian safety and mobility assessment at uncontrolled crossings is often hindered by the limitations of crash-based evaluation and the inconsistent quality of high-resolution all-traffic trajectory data collected from emerging sensing technologies. As agencies increasingly rely on behavioral …

Analysis of Association Between Demographic, Socioeconomic, and Built Environment Factors and Pedestrian Safety Using Traditional and AI Approaches
Pedestrian safety is a critical concern, particularly in urbanized areas where increasing population densities and heavy reliance on motorized transportation elevate risks for vulnerable road users who travel on foot. Creating safe, walkable environments is not only a public health priority but …

Pedestrian Safety in Peru: The role of visible signalization, transit stops and other features of the built environment
<bold>Background:</bold> In Peru, pedestrians are 78% of road fatality victims. The objective of the study was to explore the relationship between signalization for pedestrians, bus stop characteristics, and other features of the walking environment and pedestrian-motor vehicle collisions (PMVCs). …

Identification of high "risk" pedestrian locations
… identify appropriate countermeasures to improve pedestrian safety, it is necessary to identify those locations which pose high risks. The objective of this thesis is to develop criteria to identify high "risk" locations for pedestrian safety on roadway networks. These high "risk" locations were …

Development of an automated GIS tool to identify and rank high pedestrian crash zones
Pedestrian safety is an important concern on many urban streets in the United States. Identification of high pedestrian crash zones is an important component to help allocate resources to enhance pedestrian safety by reducing the number and severity of crashes in a cost effective way. High crash …

Estimating Pedestrian Crashes at Urban Signalized Intersections
… 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 …

Protection of Standing and Seated Pedestrians Using Finite Element Analysis
In the United States pedestrian fatalities in vehicle impacts have increased over the last 40 years and pedestrians who use wheelchairs (seated pedestrians) have higher mortality rates than standing pedestrians in vehicle impacts. Standing pedestrian protection has generated increased attention and …

Modification of Driver Behavior Based on Information from Pedestrian Countdown Timers
Pedestrian countdown timers (CDTs) are promoted as a means of improving pedestrian safety at intersections. However, there are concerns that drivers view the CDTs when approaching the intersection and use that information to drive more aggressively - an unintended consequence that is detrimental to …

Analysis of factors related to pedestrian high-crash locations
… and off-network factors influencing high pedestrian crash locations. The models are based on statistical analyses of crash data. These are illustrated using pedestrian crash data for the Las Vegas Metropolitan area, in Nevada, USA. Crash data were collected for a five year period …

Pedestrian Head Protection During Car To Pedestrian Accidents: In The Event Of Primary Impact With Vehicle And Secondary Impact With Ground
<p>Current regulations for assessing pedestrian safety use a simplified test setup that ignores many real-world factors. In particular, the level of protection is assessed using a free-motion headform impacting the vehicle's hood at a fixed angle. As such, this test setup does not capture the …
