In response to the rising concerns about intersection safety across the United States, traffic administrators have developed various techniques to create more effective and targeted improvement projects. Among them, Knowledge-Based Expert Systems (KBESs) demonstrate the unique advantage of having low requirements for users’ experience and efficient decision-making. This study proposes an enhanced KBES to assist […]

Speed is a contributor to both crash frequency and crash severity. This project explored efforts to reduce speed and evaluated their effectiveness in improving safety for pedestrians and bicyclists. Phase 1 was a program scan that identified countermeasures in use throughout the United States. Based on the scan, the team evaluated automated speed enforcement and […]

In the context of pedestrian and bicyclist safety, the theory of Jacobsen’s 2003 “ Safety in Numbers” (SIN) posits an inverse relationship between the extent of walking and bicycling and the probability of motorist collisions with pedestrians and bicyclists. A literature review was conducted to summarize the state of research on SIN and identify potential […]

T his fact sheet contains information on fatal motor vehicle traffic crashes based on data from the Fatality Analysis Reporting System (FARS) and non-fatal motor vehicle traffic crashes from the National Automotive Sampling System (NASS) General Estimates System (GES) and Crash Report Sampling System (CRSS). A change instituted with the release of 2020 data is […]

TUSCALOOSA, Ala. (WBRC) – Some troubling statistics on accidents involving pedestrians not just across the state, but closer to home here as well. There doesn’t seem to be a clear reason why there’s an upward trend. What is clear is that it’s happening too frequently. Here’s what we learned. Last year, law enforcement in Alabama […]

Introduction: This is the first known study that examines the association between common pedestrian crash types and passenger vehicle types. Method: The analysis included single-vehicle, single-pedestrian crashes from two data sets: North Carolina state crash data and the Fatality Analysis Reporting System (FARS). We performed separate multinomial logistic regression analyses of major pedestrian crash types […]

We have developed components of a system to identify and measure vehicle and pedestrian trajectories, speed, inter-vehicle gaps and using video feeds from arbitrary traffic surveillance cameras. The potential impact to transportation safety is the ability to detect crashes in real-time and capturing near crashes or accidents and their context. Real-time analysis allows for immediate […]

Objective: Automatic emergency braking (AEB) that detects pedestrians has great potential to reduce pedestrian crashes. The objective of this study was to examine its effects on real-world police-reported crashes. Methods: Two methods were used to assess the effects of pedestrian-detecting AEB on pedestrian crash risk. Vehicles with and without the system were examined on models […]
