This research continues recent work to investigate ways of analysing and providing for improved passing opportunities on state highways in New Zealand.
It was carried out during 2000-2001 and involved field surveys, literature review, TRARR modelling and subsequent desktop analysis.
The effectiveness of no-overtaking delineation using a modified (horizontal curve) warrant criterion was assessed.
Changes to Transfund New Zealand simplified procedures for passing-lane analysis were suggested to improve the robustness of the model.
The use and performance of slow vehicle bays were investigated and alternative evaluation procedures developed.
Various highway simulation models were assessed and a framework devised for future development of detailed rural simulation modelling on New Zealand rural roads.
