Videorecordings and traffic safety analyses of Dutch urban and rural roundabouts

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) The number of roundabouts to be contracted is at minimum 26. Additionaly 1-20 roundabouts can be contracted as options.
