Fatality risk by travel mode in England

Mindell, Lesley, Wardlaw. “Exposure-based Assessment of Modal Travel Risk in England Using Routine Health Data,” Journal of Epidemiology and Community Health, September 13, 2012.

Young male drivers appear to have a higher fatality risk than cyclists in England. This is latched onto as quite good news for cyclists. The results of this study depend entirely on responses given on Britain’s National Travel Survey.

Results: Fatalities per million hours’ use (f/mhu) varied little (0.15–0.45f/mhu by mode for men, 0.09–0.31f/mhu for women). Risks were similar for men aged 21–49 years for all three modes and for female pedestrians and drivers aged 21–69 years. The group most at risk for each mode were: male drivers aged 17–20 years (1.3f/mhu, 95% CI 1.2, 1.4); male cyclists aged 70 years or older (2.2 f/mhu, 1.6, 3.0) and female pedestrians aged 70 years or older (0.95 f/mhu, 0.86, 1.1). In general, fatality rates were substantially higher amongst males than females, except for drivers aged 60 years or older. Risks per hour for male drivers under 30 years were similar or higher than for male cyclists; for 17–20 year olds the risk was higher for drivers (33/Bn km, 95% CI 30, 36; 1.3f/mhu, 1.2, 1.4) than cyclists (20/Bn km, 10, 37; 0.24f/mhu, 0.12, 0.45) using distance or time.
