North Shore Busway Evaluation.pdf

The North Shore Busway, a proposed two-lane carriageway for buses and high occupancy vehicles (HOVs) from Albany to the Auckland Harbour Bridge, faces funding and evaluation challenges due to differing requirements from key stakeholders, Transfund New Zealand and Infrastructure Auckland. The project aims to improve public transport by providing high-quality bus services and reducing congestion. The evaluation process involved:

1. Model Development: An existing transport model was extended and updated to accommodate a multiclass assignment and public passenger user classes, enabling evaluation of busway stations and services.

2. Modal Split: A 'pivot point' model was used to reallocate trips between modes based on changes in accessibility, measured through cost of travel.

3. Trip Matrices: Trip matrices for 2000 were derived for car drivers, HOV drivers, HOV passengers, bus passengers, and ferry passengers. Future trips for 2005 and 2011 were estimated using land use data.

4. Evaluation: The model was used to forecast trips, apply a pivot point mode split, and adjust for changes in generalised costs for both base and option cases.

The paper highlights issues for future analysis of proposals with significant public transport components but does not include the results of the evaluation, as these have not yet been considered by funding agencies.
