Purpose of Database:
The Federal Highway Administration (FHWA), with the assistance of the U.S. Department of Transportation’s (DOT) Volpe National Transportation Systems Center (Volpe Center), has developed the Statewide Long-Range Transportation Plan (SLRTP) Database as a technical resource for State DOTs and other stakeholders.

For comments or questions on the database or accompanying report, please contact Erica Simmons, Volpe Center project manager (

The information in the database is based on the research team’s review of 52 state long-range transportation plans from all 50 states, the District of Columbia, and Puerto Rico. An accompanying report (available here) provides analysis from the review and summarizes detailed findings. FHWA and the Volpe Center used the previous report (available here) to inform the research on priority topics of interest for the review of statewide long-range transportation plans.

Topics in Database:
The database presents information on how individual plans address the following ten transportation planning topics:

  • Plan type: identifies a plan’s primary focus or orientation. The seven major plan types are described below:
    • Performance-based SLRTPs: use quantifiable metrics, targets, or timeframes to guide planning, project development, maintenance, and operations decisions.
    • Policy-based SLRTPs: provide strategies to outline general transportation directions for the State, address transportation needs, or meet projected demands. While all SLRTPs reference policies to some extent, policy-based SLRTPs are primarily focused on outlining policy directions and typically do not include highly detailed references to elements (e.g., investment scenarios, performance measures, specific projects) that are included in SLRTPs representing other plan types.
    • Corridor-based SLRTPs: focus on specific transportation corridors (e.g., single modal, multimodal, and intermodal transportation networks within a specific geographic area) through description of major corridors, project needs, consideration of corridor conditions, or description of potential corridor projects.
    • Needs-based SLRTPs: analyze transportation needs for the State by considering available or alternative revenue sources or through reference to demographic or travel demand projections.
    • Vision-based SLRTPs: identify an ideal future State transportation system, often through incorporating public input on a preferred vision.
    • Financially realistic SLRTPs: set long-term directions for the State’s transportation system through analysis of projected capital and operating costs and revenues of the plan’s time horizon.
    • Project-based SLRTPs: reflect assessment of alternative investments to meet the SLRTP’s transportation policies or goals.
  • Systems Planning: focuses on planning efficient and effective multimodal transportation networks as opposed to planning each mode as a separate component of the network. This section identifies transportation modes addressed within the plan, including intercity passenger service, ports, and connected/automated vehicles.
  • Performance-Based Planning and Programming: uses data in long-range planning and project programming to support decisions that help to achieve performance goals. This section identifies plan goals, performance measures, and performance targets, as well as plans with comprehensive approaches to performance-based planning and programming.
  • Implementation Approaches: reflect States’ decision-making processes, including policy directions, project prioritization, and funding priorities. States can implement SLRTPs through policy and practices and/or investment strategies.
  • Financial Analysis and Funding Strategies: explores the plans’ inclusion of certain elements of financial planning or analysis, such as estimates for needs, revenues, costs, and budget shortfalls, as well as funding strategies or innovative funding methods.
  • Challenges and Trends: discusses challenges, such as revenue shortfalls for transportation, inflation, aging infrastructure, aging population, and climate change, and trends, such as technology, congestion management, demand management, freight, assessment management, and emerging mobility.
  • Noteworthy and Innovative Methods: discusses methods in several SLRTPs to improve analysis and communication, including Geographic Information Systems (GIS), data visualization, and scenario planning.
  • Special Topics: identifies specific topics that may be of special interest in relation to transportation legislation, such as travel and tourism, community development, and safety.

Note: the information provided in the database is not intended as an exhaustive representation of how a topic was addressed in a state’s transportation planning process. The plan review was completed in December 2016 and focused on the information included in a state’s long-range transportation plan that was available at the time the review was conducted.
