An efficient solution to toll choices involving multiple toll booths and/or multiple tolling strategies.

The recent opening of Sydney's Westlink M7 Motorway has crystallized deficiencies in traditional toll road demand forecasting approaches. The Westlink M7 distance-based, capped toll cannot be efficiently modelled using an assignment with the toll incorporated into the generalised cost, and traditional behavioural route choice models encounter convergence, run-time and potential market issues given the sheer number of toll segments to be evaluated (where a toll segment is the combination of toll booths available for a particular trip). These deficiencies are exacerbated by the construction of more urban toll roads together with the possibility of more complex tolling strategies permitted by electronic tolling. A new behavioural route choice model is proposed which provides an efficient solution to toll choices involving multiple toll booths and/or multiple tolling strategies (eg toll caps, toll discounts). The solution is implemented in the commercial FASTOLL software package. (a) For the covering entry of this conference, please see ITRD abstract no. E214666.
