Evaluation of signalised high-volume multi-lane turbo roundabouts : road scene analysis, road user survey, and video-based analysis of road user behaviour
other
The Province of Zuid-Holland has introduced the signalised high-volume multi-lane 'Turbo roundabout' as a new intersection lay-out with the most important characteristic that there are physically separated driving directions, in contrast to conventional roundabouts. TNO evaluated two existing signalised turbo roundabouts with respect to traffic flow and road users' behaviour and experience. The evaluation of road users' behaviour and experience consisted of a road scene analysis by two human factors experts, a behavioural analysis based on video recordings and a road user survey in the direct vicinity of one of the turbo roundabouts. For each turbo roundabout, eleven hours of digital video recordings were analysed for error manoeuvres and other deviant behaviour for each approach branch.
Evaluatie van met verkeerslichten geregelde turbopleinen door wegbeeldanalyses, analysegedrag weggebruikers en enquetes lsaat zien dat weggebruikers ze complex vinden en dat geeft fouten. Terughoudendheid in toepassing lijkt geboden
