CTP Modeling & Policy Scenario Development

The California Transportation Plan (CTP) Modeling and Policy Scenario Development Flow Chart provides a visual representation of how information, data, scenarios, and models interact and flow as you move from left to right. The Flow Chart is broken into five groups: Inputs, Scenario Modeling, Initial Outputs, Economic and Emissions Modeling and Final Results. It shows a generalized overview of how the CTP 2040 will calculate final results such as greenhouse gas (GHG) emissions, gross state product (GSP), mode split, vehicle miles traveled (VMT), vehicle hours of delay (VHD) and commodity flow by tonnage and mode among many others.
