A long-range transportation plan (LRTP) must project transportation demand for persons and goods over the period of the plan. To complete this task, the MPO must develop a growth scenario that forecasts housing and employment growth out to the plan’s horizon year and identifies where this growth will likely occur. The growth scenario process is important in that it feeds into the MPO’s travel demand model. The model is used to estimate traffic flows into the future and helps to inform planning decisions.
Please follow the steps in the “Growth Scenario Instructions” document linked below and submit your updated Growth Scenario Spreadsheet to Zach Young, zyoung@dmampo.org by June 28, 2024.
