However, crashes do occur at signalised intersections and because of the combination of high speeds and right angle crash configurations, they are likely to cause harm to those involved. Filter right turns present substantial danger to road users due to the complexity of decision making, risk of severe outcomes and the lack of control being placed over road user movements. The main aim of this research is to use footage of filter right turn crashes at signalised intersections to identify and analyse crash mechanisms associated with these crashes, and to develop recommendations that can lessen or eliminate the risk of filter right turn crashes should full right turn control not be able to be employed. A number of recommendations are made and include fully controlling right turns or where filter turns are allowed, reducing through vehicle speeds and control right turns at off-peak times when volumes do not warrant filter turns. It is also recommended that this study be revisited on a frequent basis and that further research be undertaken to better understand specific issues of dynamic visual obstruction and drivers’ abilities to judge speed and distance at night. | | Report Number | CASR152 | | Publisher | Centre for Automotive Safety Research | | Publisher City | Adelaide | | Sponsor | This research was funded via a deed with the South Australian Government | | ISBN | 978-1-921645-90-7 | | ISSN | 1449-2237 | | Page Count | 22 |
