Since 1988, the SWOV Institute for Road Safety Research has been publishing key risk indexes for road safety that describe the safety level on various road types. In the most recent updating of key risk indexes in 1995, key risk indexes for lower-order roads (residential roads, roads in pedestrian precincts, and rural roads), as well as data about slow traffic, were not represented. Key risk indexes for lower-order roads, however, could actually play an important role in improving road safety. Key risk indexes could also provide additional insight into slow traffic, in this report limited to bicycle traffic. The report provides a detailed description of possible forms and calculation methods for the key risk indexes. The report provides a detailed examination of the size of the needed databases, statistical considerations involved in the gathering of data, and possible processing techniques. For the first part see C 11053 (IRRD 491568).
