走路里程要多少時間才能跟單車里程相比?
研究中有提到，以距離為基準，每十億公里頭部傷害死亡率為:
單車: 11.2 (95% CI 9.7–12.9)
行走: 23.4 (21.8–25.0)
開車: 0.7 (0.6–0.7)
以時間為基準，每一百萬小時頭部傷害死亡率為:
單車: 0.16 (0.14–0.19)
行走: 0.10 (0.10–0.11)
開車: 0.03 (0.028–0.032)
就算用時間來比，單車的危險性也僅略高於行走 (而且我相信絕大部分人花在走路上的時間遠超過騎車)
Rates of fatal head injury per bnkm in males aged 17+ for cycling, walking, and driving were 11.2(95% CI 9.7–12.9), 23.4(21.8–25.0) and 0.7(0.6–0.7) respectively. Female fatality rates were 8.8(6.2–12.0), 9.6(8.7–10.7) and 0.4(0.4–0.5) per bnkm respectively. Using time as the denominator, rates were 0.16(0.14–0.19),0.10(0.10–0.11) and 0.03 (0.028–0.032) respectively in men and 0.10 (0.07–0.14), 0.04(0.037–0.045), and 0.01(0.012–0.016) respectively in women, per million hours travelled.
