Development of fatality and injury risk relationships for cyclist-vehicle impacts
Submission Date: 2019
There is very little literature addressing cyclist fatality and serious injury (FSI) risk in impacts with motor vehicles. This study built on established curves relating pedestrian FSI risk to vehicle impact speed and incorporated the effects of cyclist speed and impact angle. A technique was developed that considered a vehicle-cyclist crash as two impacts: (a) the first impact between the cyclist and the vehicle and; (b) the second impact between the cyclist and road/roadside infrastructure. Combining the FSI risk of each yielded an estimate of cyclist FSI risk. This pilot method will need to be validated using real-world data.
