SWOV is preparing a site-based conflict observation study on the safety of cyclists and pedestrians on Dutch roundabouts for motorised traffic. The objective is to obtain a quantitative picture of the safety effects of design features at selected roundabouts in urban and rural areas of the Netherlands.
Main required quantitative outcome measures: Time To Collision, Post Encroachment Time, traffic flow per modality, speed and trajectory per road user.
Important roundabout design features:
-Cyclists having priority/no priority crossing a road attached to the roundabout.
-One/two direction cycle paths.
-Distance from roundabout area to cycling/pedestrian crossing.
-Separate cycling infrastructure or cyclists sharing the roundabout.
SWOV seeks a Contractor to:
-Record video data with two cameras for two weeks per roundabout including getting permits for video recording per authority
-Perform safety and behaviour analysis
-Deliver analyses/data
Number roundabouts: 26 (1-20 optional)
