Abstract
Stage 2 of Transfund New Zealand's research project "Assessing Passing Opportunities" builds on initial work that investigated ways in which improved passing opportunities can be provided and analysed. The subsequent work investigates the development of a simpler system to determine the need for, location of, and benefits to be derived from passing lanes. This paper discusses the findings of a driver frustration study, and some of the resulting implications for the development of a simplified system. Drivers' willingness to pay for additional passing opportunities was found to be significantly correlated with the easily measurable unsatisfied passing demand, although further work is required to refine the relationship.
