Summary
This study investigates the factors associated with fatal pedestrian crashes in Virginia’s urban areas between 1985 and 1987. Motivated by the fact that more than half of Virginia’s pedestrian fatalities occurred in urban settings, the Virginia Transportation Research Council analyzed 216 fatal crashes to identify contributing characteristics and develop safety measures. The research utilized police accident reports, supplemented by medical examiner toxicology data where necessary, and employed statistical analysis to examine pedestrian, driver, roadway, and vehicle factors. The findings indicate that negligent pedestrian behavior was the primary contributor to fatalities, outweighing driver error, roadway conditions, or vehicle factors. Alcohol and drug use by pedestrians was a major cause, affecting 34.2% of cases. Among pedestrians aged 20–64, alcohol involvement was high, with 57.7% of those with reported blood alcohol concentrations (BAC) exceeding 0.20%. In contrast, alcohol was rarely a factor for pedestrians under 20 or over 75. Demographically, males accounted for 77.3% of fatalities despite comprising only 48.6% of the urban population, with fatality rates significantly higher than females across all age groups. Elderly pedestrians (55+) were particularly vulnerable, being seven times more likely to be struck while crossing the street than while walking along the roadway, and exhibited the highest fatality rates. Temporal and environmental patterns revealed that crashes peaked during the fall and winter months, particularly in October. Approximately 60% of fatalities occurred between 4 p.m. and midnight, with the highest concentration from Thursday through Saturday. Darkness was a critical factor; 66% of crashes occurred during dark conditions, and 58% of those occurred on unlighted roadways, despite 65% of crashes happening in clear weather. Driver factors showed that younger males (20–34) were overrepresented, and drivers were cited for traffic violations in only 36% of cases, with hit-and-run being the most frequent offense. Drivers were sober in approximately 80% of incidents. Vehicle data indicated that striking vehicles were traveling straight in 87% of cases and at speeds of at least 40 mph in nearly 50% of cases. The study concludes that pedestrian behavior, particularly alcohol impairment and risk-taking, is the dominant factor in urban pedestrian fatalities in Virginia. The authors recommend further investigation into age- and sex-specific behavioral differences, the development of targeted safety programs for pedestrians and drivers, traffic engineering enhancements, and the integration of effective child safety strategies into programs for the elderly. The results align with national trends, except for Virginia’s lower fatality rate among young children.
Key finding
Negligent pedestrian behavior and alcohol impairment were the dominant factors in fatal urban pedestrian crashes, with elderly pedestrians and males showing significantly higher fatality rates.
