Analyzing roadway factors influencing the severity of non-motorized road users' crashes in Charlotte, North Carolina, USA
As U.S. cities expand multimodal transportation networks and pursue Vision Zero goals, crash severity among pedestrians and bicyclists remains a critical public safety challenge. Charlotte, NC, offers a timely case study given its rapid urban growth, rising active transportation demand, and commitment to Vision Zero. T...

High Traffic, High Impact: Preliminary Data on Roadkill Rates from Murchison Falls National Park, Uganda.
Wildlife mortality by animal-vehicle-collisions in Uganda's protected areas is poorly understood. We present baseline roadkill data from Murchison Falls National Park collected over 32 consecutive days, 10 December 2024-10 January 2025, along an 86 km tarmac road and a 56 km murram (unpaved) road.Over 18 176 km of road...

A Multi-Method Spatial and Statistical Assessment of Road Accident Risk and the Regional Accident Risk Index (RARI) in Tanzania
This study analyzes road traffic accident risk in Tanzania and introduces a composite Regional Road Accident Risk Index (RARI), defined as accidents per 100 km of road, to compare regional risk and assess progress toward SDG 3.6. A multi-method approach was used: national traffic fatality trends from 2000–2022 were mod...

Bicyclist overtaking in naturalistic riding data: Speed, clearance, and implications for injury risk.
OBJECTIVE Motor vehicle passing speed and lateral clearance jointly determine both bicyclist injury risk and perceived safety during overtaking events. Most prior studies have examined these factors separately and/or in limited settings. Real-world evidence describing how passing speed and clearance interact across het...

Comprehensive Assessment Framework for Collision Risk in Wide-Range Expressway Diverging Area Using Two-Dimensional Vehicle Trajectory Data
Expressway diverging areas exhibit a higher vehicle collision risk than basic segments due to frequent weaving and diverging traffic. Existing studies rely on 1D indicators and focus on the exit ramp and adjacent downstream sections, underestimating collision risks in wide-range diverging areas. This study proposes a...

Animal-vehicle collisions, roadkilled animals, and human health: A scoping review protocol
Background Animal-vehicle collisions (AVCs) are a growing global problem with significant implications for human, animal, and ecosystem health. In the United States, approximately one million vertebrates are killed by vehicles each day. Research on roadkilled animals has increased over time, especially regarding wildli...
