Economics and Financing

This report describes the results of a review of international literature undertaken in 2002 on the evaluation and application of intermittent overtaking lanes on two-way roads in rural traffic environments. This report also contains a comprehensive outline of the history of traffic simulation and the development of the TRARR and TWOPAS traffic simulation models, noting that TWOPAS is no longer available as a stand-alone model. In addition, the main aspects of TRARR and TWOPAS are compared, and suggestions are made for preliminary work that would be necessary in the now unlikely event that TWOPAS is seriously considered for use in Australia or New Zealand.
