Orange City Council is seeking proposals from suitably qualified consultants to prepare the 2025 Orange Strategic Transport Model Update.

The Orange Strategic Transport Model (OSTM) is based on the four-stage (Trip Generation, Trip Distribution, Modal Split and Trip assignment) modelling framework.

The OSTM was last calibrated seven years ago. To enhance the model's ability to produce more accurate forecasts, it needs to be recalibrated to replicate the current (2025) conditions in terms of demographics, transport network and travel conditions.

Orange City Council is seeking a suitably qualified professional services contractor to update the model to represent current conditions and to estimate future travel demands and travel conditions.
