Balance Needs of Rural Connectivity and Urban Congestion/Mobility

  • Initial distribution aligns with current estimated road usage between urban and rural areas of the state.

Vehicle Miles of Travel (Million - 2015 Annual Est)*

* Est. VMT based on TxDOT 2015 Road-Highway Inventory Network (RHiNo) data on Major Collector roads and higher.
Rural VMT 61,056 23%
Urban VMT 202,431 77%
TOTAL 263,487 100%

Additional Funding ($Million - 10 Year UTP)

Rural Connectivity $ 6,206 23%
Congestion $ 21,197 77%
Total $ 27,403 100%

  • Future changes to allocations will consider changes in road usage and forecasted impacts from proposed improvements in order to balance statewide needs and system performance.

Congestion and Urban Mobility ($28.9 Billion – Total UTP Funding)

  • Total UTP Congestion Relief funding = $28.9 billion over 10 years.
  • Initiative includes funding from:

Funding Category
10 Year Additional Funding
($ Billion)
Cat. 2 – Metropolitan & Urban Corridors
$12.5
Cat. 4 – Connectivity 
5.0
Cat. 5 – Congestion Mitigation & Air Quality
2.2
Cat. 7 – Metropolitan Mobility & Rehabilitation
4.2
Cat. 12 – Strategic Priority (Clear Lanes Initiative)
5.0
TOTAL
$28.9
  • Category 2 distribution includes an additional $11.2 Billion to all 25 MPOs statewide.
  • Formula data is updated each year to reflect current traffic volume, population, and other factors which results in changes to distributions within each category. For example, when distributing Cat. 2 funds to MPOs, formula factors could change resulting in the addition or reduction of funding from previous years.

Congestion and Urban Mobility – Category 2 Funding

  • Priorities include establishing partnerships with districts and MPOs to:
    • Target congestion and improve safety in metro and urban areas.
    • Use performance-based project selection to optimize system performance.
    • Provide a strategic focus on congested areas and key trade corridors.
  • Funds distributed by agreed upon formula that includes consideration of:
    • Population
    • Total traffic (vehicle miles of travel)
    • Miles of highways
    • Truck traffic
  • Projects selected and ranked by MPOs in consultation with TxDOT Districts, and approved by the Commission.
