Summary

This document is a statistical report published by the Wyoming Department of Transportation’s Highway Safety Program, detailing traffic crash data for the year 2007. The report serves as a comprehensive resource for analyzing roadway safety trends, providing granular data on crash frequencies, severities, and contributing factors across the state. It is motivated by the need to provide detailed statistical information to stakeholders, policymakers, and the public to inform highway safety initiatives. The report aggregates data from 17,429 total traffic crashes, categorized into 136 fatal crashes, 4,366 injury crashes, and 12,927 property-damage-only crashes. These incidents resulted in 149 fatalities and 6,620 non-fatal injuries. The analysis covers multiple dimensions, including geographic distribution by county and rural versus urban settings, temporal patterns by month and day of the week, and specific crash types such as motor vehicle-to-motor vehicle, overturns, and collisions with fixed objects or animals. Specialized sections analyze crashes involving alcohol, drivers aged 14–20, trucks, school buses, and motorcycles. The data also examines human factors (e.g., driver age, sex, safety equipment usage), environmental conditions (e.g., weather, road surface, lighting), and vehicle elements (e.g., mechanical defects, speed). Key findings indicate that Natrona County recorded the highest number of total crashes, while Sweetwater County had the most fatal crashes. Overturns were the most frequent type of fatal crash, and motor vehicle-to-motor vehicle collisions were the most common crash type overall. December saw the highest volume of crashes, and Fridays recorded the most incidents. Alcohol was involved in 46 fatal crashes. The report highlights that 89% of occupants reported using safety equipment. Rural areas accounted for 7,557 crashes compared to 9,872 in urban areas, though rural crashes comprised a significant portion of fatalities (111 out of 136). The fatality rate for Wyoming in 2007 was 1.61 per 100 million vehicle miles traveled, slightly higher than the U.S. rate of 1.41. The significance of this report lies in its role as a foundational dataset for identifying high-risk areas and behaviors within Wyoming’s transportation network. By breaking down crash data by county, time, and contributing factors, the report enables targeted safety interventions. For instance, the high prevalence of overturns and alcohol-involved fatal crashes suggests areas for focused enforcement and education. The detailed comparison of rural and urban crash patterns, along with specific analyses of vulnerable road users like pedestrians and motorcyclists, provides evidence-based insights crucial for improving roadway design, traffic control measures, and public safety campaigns.

Key finding

Wyoming recorded 17,429 traffic crashes in 2007, resulting in 149 fatalities, 6,620 non-fatal injuries, and an estimated economic loss of $440,657,800.
