OKI Travel Demand Model

The data services department is primarily responsible for the development of the OKI Regional Travel Demand Model.  The travel demand model is a tool to forecast traffic volume, transit ridership, and vehicle emissions in the future.  The model forecasts these data elements by:

1. Determining the number of people traveling from and to every traffic analysis zone

2. Forecasting where those people will go

3. Calculate the utility of each available travel mode (drive alone, shared ride, transit) and use that to determine the probability of using each mode

4. Assign the people to vehicles, busses, etc., and assign them to the network

The OKI Model is a modified four-step model that performs trip generation, distribution, mode choice, and assignment for the OKI and MVRPC regions.  The model is run in Cube Voyager software, although some model steps utilize Cube TranPlan software, and still others use custom programs.

While the model covers both OKI and MVRPC regions, OKI maintains the inputs for the OKI Region, and MVRPC maintains the inputs for their region.
