“…This effect was suggested earlier (e.g., Brilon, 1997). However, in their cross-sectional study, Hels and Orozova-Bekkevold (2007) found no significant effect of the presence of a cycle facility on the number of bicyclist crashes.…”

Problem: Previous research indicated that conversions of intersections into roundabouts appear to increase the number of injury crashes with bicyclists. However, it was assumed that the effectiveness of roundabouts could vary according to some differences in design types of cycle, facilities and other geometrical factors. Method: Regression analyses on effectiveness-indices resulting from a before-and-after study of injury crashes with bicyclists at 90 roundabouts in Flanders, Belgium. Results: Regarding all injury crashes with bicyclists, roundabouts with cycle lanes appear to perform significantly worse compared to three other design types (mixed traffic, separate cycle paths, and grade-separated cycle paths). Nevertheless, an increase of the severest crashes was noticed, regardless of the design type of the cycle facilities. Roundabouts that are replacing signal-controlled intersections seem to have had a worse evolution compared to roundabouts on other types of intersections. Impact on industry: The results might affect design guidelines for roundabouts, particularly for the accommodation of bicyclists.

“…The effects of some other variables have been investigated in different studies. Hels and Orozova-Bekkevold (2007) found a significant positive relationship between the drive curve as a proxy for potential vehicle speeds and the number of bicyclist crashes. A similar effect was reported by Layfield and Maycock (1986).…”

“…Roundabouts are known to cause fewer traffic accidents compared with traditional junctions (Hels and Orozova-Bekkevold, 2007). To investigate this, the total number of roundabouts within a ward was included in all models.…”

“…Only Great Britain (66%) covers over 30% of the cyclist crashes. In Denmark, Hels and Orozova-Bekkevold (2007) found that in a five year period, only 25% of emergency room cyclist crashes were reported by the police.…”

While national crash databases are a valuable resource for the analysis of crash frequency and severity, these databases consist of police reports that are known to be heavily under-reported. This study aligns to the body of research dedicated to estimating the under-reporting rate of crashes by employing the capture-recapture method on available medical and police records. Data consist of records of road users who reported their involvement in a road crash to the police or emergency rooms on the island of Funen in Denmark between 2003 and 2007. Moreover, this study estimates the likelihood for road users reported in police records to appear in hospital records (and vice versa) by estimating joint binary logit models. Results show that the likelihood of appearing in both datasets is positively related to helmet and seat-belt use, number of motor vehicles involved, alcohol involvement, higher speeds and lane number, and females injured. Marital status and education level are not found to be associated with the probability of reporting both to the hospital and the police.
