Revenue forecasting

We create 10-year outlook quarterly transportation revenue forecasts for the Transportation Revenue Forecast Council (TRFC):

• Motor fuel tax revenue.
• Motor vehicle licenses, permits, and fee revenue.
• Other transportation related revenues.
• Federal funds.
• Economic variable forecasts including fuel prices.

The TRFC is overseen by the Governor's Office of Financial Management (OFM) and forecasts are published quarterly on their website. If you would like to get the forecasts in excel format, contact us.

State economic and financial data

We track tax collections and other relevant economic indicators (like fuel prices, employment and personal income) and use that data in our transportation forecast models and revenue and economic statistics projections. We also file state and local financial reports with the Federal Highway Administration (FHWA) and we collect local financial data from local governments.
