Roundabouts reduce casualty crashes by 75% for all vehicles, yet when looking at motorcyclists in particular, they only reduce casualty crashes by 37%.
Our research shows that the top 10 road environment factors that influence risk for motorcyclists at roundabouts are:
- geometric design
- number of lanes
- sight distance
- lighting
- pavement markings
- signing
- landscaping
- street furniture
- speed limits
- surface issues
