Research has suggested that motorcyclists involved in approach-turn crashes were much more injurious than any other crash-type. This paper investigates the determinants of motorcyclist injury severity resulting from such crash types that occurred at T-junctions, with emphasis on the effects of driver's failure to give way and various junction control measures. The ordered probit models of motorcyclist injury severity were estimated using the data extracted from the STATS19 accident injury database (1991-2004). Approach-turn collisions are categorised into two sub-crashes based on the manoeuvres motorcycles and vehicles were making prior to the collisions. The modelling results uncover several important determinants of injury severity: for example, injuries appeared to be greatest when an approaching motorcycle collided with a turning-right vehicle, and such effect was found to exacerbate injury severity when stop, give-way signs and markings controlled the junction. A turning-right driver that was identified to fail to yield to an approaching motorcyclist was also found to severely injure the motorcyclist. The findings of this study may offer guidelines for further research and provide some important preliminary evidence for the development of countermeasures that may help prevent the specific hazards from occurring.
研究表明，涉及驶入转弯碰撞事故的摩托车手比其他任何类型的碰撞事故更容易受伤。本文调查了在T型路口发生的此类碰撞事故导致摩托车手受伤严重程度的决定因素，重点关注驾驶员未让路的影响以及各种路口控制措施。使用从STATS19事故伤害数据库（1991 - 2004年）提取的数据，估计了摩托车手受伤严重程度的有序概率模型。根据摩托车和车辆在碰撞前的操作，驶入转弯碰撞被分为两种子碰撞类型。建模结果揭示了几个影响受伤严重程度的重要决定因素：例如，当一辆驶来的摩托车与一辆右转车辆相撞时，受伤似乎最为严重，并且当停车、让行标志和标线控制路口时，这种影响会加剧受伤的严重程度。还发现，被认定未让驶来的摩托车手先行的右转驾驶员也会使摩托车手受重伤。本研究的结果可能为进一步研究提供指导，并为制定有助于预防特定危险发生的对策提供一些重要的初步证据。
