SEMCOG’s Travel Demand Forecast Model estimates current and forecast motorized vehicle travel volumes, speed, and patterns in Southeast Michigan. The data is used to inform policies, develop projects, and identify opportunities for collaborative initiatives contained in SEMCOG’s long-range transportation plan.

For day-to-day operations, the travel model adds value to SEMCOG members by:

  • supporting master plan updates,
  • analyzing traffic safety improvements,
  • considering economic development impacts, and
  • determining air quality conformity.

Travel modeling is both required and essential to planning efforts at SEMCOG. This model is constantly refined. Data inputs such as population, employment, and households are updated to reflect current demographics. Data outputs compare favorably with those of other regional area models of the same size.
