Motorcycles are frequently used in middle- and low-income societies. They are often involved in crashes, and account for a noticeable percentage of fatalities secondary to crashes. Comparing motor-vehicle occupants and motorcycle riders, the present study examined the survival hazard of crash injuries with respect to road environmental factors (i.e., area, road type, and location). We investigated the effects of such factors on survival and survival time after crashes via a binary logistic regression analysis and a Cox proportional hazard regression analysis, respectively. Results indicated that, for both motor-vehicle occupants and motorcycle riders, the fatal prevalence, occurrence likelihood, and risk based on time were decreased in urban areas and elevated on highways. The three indexes were also higher for motor-vehicle occupants on non-straight or non-level roadway sections. The prevalence of death on local roads and at intersections was relatively higher for motorcycle riders compared to motor-vehicle occupants. Speed may contribute to the survival hazard with respect to road environment factors. Speed management initiatives account for hazardous roadway, curve alignment re-examination, and increased traffic enforcement density are suggested. Collaboration among the roadway authorities, vehicle industry, and medical systems for a timely rescue is also advised. In addition, the attention to crashes at intersections and on local roads is a promising intervention for motorcycle riders.
摩托车在中低收入社会中经常被使用。它们经常涉及事故，并在由事故导致的死亡中占有相当大的比例。本研究比较了机动车乘客和摩托车骑手，研究了道路环境因素（即地区、道路类型和位置）对碰撞伤害的生存风险。我们分别通过二项逻辑回归分析和 Cox 比例风险回归分析，研究了这些因素对生存和碰撞后生存时间的影响。结果表明，对于机动车乘客和摩托车骑手来说，在城市地区，致命性发生率、发生可能性和基于时间的风险均降低，而在高速公路上则升高。对于非直线路段和非水平路段的机动车乘客，这三个指标也更高。与机动车乘客相比，当地道路和交叉口的死亡发生率相对较高。速度可能是导致道路环境因素的生存风险的原因。建议采取危险道路管理措施、重新检查弯道的路线和增加交通执法密度。还建议道路管理部门、车辆行业和医疗系统之间的合作，以便及时进行救援。此外，关注交叉口和当地道路的事故是对摩托车骑手进行干预的一个有前途的方法。
