Parramatta CiTran Multi-Modal Model — Mode Choice

This model was used to determine the optimal split of car and public transport users into the Parramatta CBD, the “second Sydney CBD” in the Sydney metropolitan area. We built the model in conjunction with Parramatta City Council: the Council owned the data and we owned the maths. Parramatta City Council purchased the Emme software licence, and we trained council staff to run the model in-house.

The model uses the incremental mode-choice approach outlined in Heinz Spiess’s paper on Incremental Logit Demand Functions, with future car demand constrained by the available parking spaces in each zone. The model received good reviews from RMS technical staff, and many in-house studies have since been undertaken using it, often with our assistance on the more technical aspects.
