"According to several studies, the rate of death is lower for travel on public transport than that in cars. For example, in the USA, fatality rate for car occupants were found to be 23 times higher than those for bus occupants, per 100 million person-trips [3]. Another study found fatality rate to be as high as 66 times greater for car occupants than those for bus occupants per passenger-mile traveled [4]. Similarly in Australia, car occupants have nine times greater rate of death than bus occupants, per hour traveled [5]. In Europe, car occupants have ten times greater rate of death compared to bus occupants and 20 times greater rate of death compared to train occupants, per kilometer traveled [6]. The non-fatal injury rate is also higher for car occupants compared to that for bus occupants: 4.3 times higher per kilometer traveled in Norway [7] and 5.0 times higher per person-trips in the USA [3]. "
These studies aggregated data for entire countries or groups of countries and therefore cannot describe the potential spatial variation across regions and contexts (e.g., urban versus rural). Furthermore, at the country level, no distinction is usually made between different types of busses (e.g., school bus, intercity, urban transit) [3, 6, 8], except for one study which only looked at fatality rates [9].
人地擺落 background 就正正係其他 study 有不足，唔係做義工幫你整合人地嘅 research
我記得前面應該討論過香港巴士模式嘅獨特性？mixed intercity & urban transit 呢點應該唔洗我講？
另外 conclusion 雖然係話巴士比較安全，但同時間份 study 自己都好 aware 強調要留意路線性質上嘅分別：
This study shows that city bus is a safer mode than car, for vehicle occupants but also for pedestrians and cyclists traveling along these bus routes. Although bus travel is safer on all specific routes, there is great variation in the safety benefits at the route level. The variation in injury rates and safety benefits of public transit is likely caused by road geometry and other environmental factors; disaggregate analyses at the route level are necessary to determine their effects. The results at the route level will provide vital information for cities to properly orient the implementation of environmental changes as preventative strategies to reduce the risk of injury for all road users.
佢 focus 係在於 city bus / urban transit 如果照攞 conclusion 套落香港係咪穩妥？
