A long range transportation plan is a tool used by federal, state, and local entities to evaluate transportation assets and to plan for future needs. The Statewide Transportation Plan is a long-range plan that assesses the State’s multimodal transportation system and presents plans for improvement and maintenance. The plan will forecast a minimum of 20 years, and will involve engagement with both public and private entities. The plan is designed to meet the goals and other requirements required by federal legislation, including the new FAST Act with its emphasis on performance management.

The Statewide Transportation Plan will include both a document and a travel demand model. The document will provide a means to display the State’s current assets and examine where work will be needed in the future. The travel demand model will be used to forecast traffic to help identify future needs. Alabama’s transportation infrastructure includes the highway system, transit and rail lines, bicycle and pedestrian operations, freight operations, airports, and river and seaports.

This website will continue to be updated as the development of the Statewide Transportation Plan gets underway. Deliverables will include interim reports, mapping, and other related information. The previous statewide transportation plan is available here. An assessment of the existing transportation system was also performed in 2008 and that document is available here.

Alabama Statewide Transportation Plan

Alabama Statewide Transportation Plan

Alabama’s highway network provides connectivity for passenger vehicles as well as goods and services. Roadways are described by the federal functional classification system, which defines a roadway based on its accessibility and mobility. Interstates provide the most mobility, while local roads provide the most accessibility. ALDOT uses a number of tools to determine the future highway needs of the State, such tools include the ALGO Traffic Incident Management System, the MPO travel demand model, and various local and statewide transportation plans.

Rail exists in Alabama for the purpose of moving passengers and freight. Amtrak is the major mover of passengers and there are four class 1 railroads operating in Alabama. The Alabama Department of Transportation looks at rail movement from several angles. There is the need to understand freight movement and the major generators of that freight movement. Safety planners also need to monitor rail grade crossings to examine the potential for accidents.

What is the Statewide Transportation Plan?

The Statewide Transportation Plan (SWTP) is the result of the statewide planning process that reviews long range transportation needs in the state, seeks public input on priorities of stakeholders and communities, evaluates funding resources and develops recommendations for programs, policies and transportation initiatives.

Why is it important to update the SWTP?

It is important to maintain oversight of the condition and operation of transportation programs so that the State is able to respond to evolving transportation demands. As the State grows and businesses establish themselves in Alabama, the Department's goal is to provide mobility that facilitates access to jobs, education, commerce and other trip purposes.

The SWTP is also a federal requirement in order to maintain eligibility for federal funds. Transportation projects will usually require years of preparation to accomplish. The SWTP looks ahead to identify emerging needs and evaluate how best to meet the transportation needs of citizens. Projects included in the STIP should be in keeping with the needs identified in the SWTP.

What modes of transportation are included in the SWTP?

The SWTP is multimodal and includes roads and bridges, transit, bicycle, pedestrian, freight transportation, passenger rail and aviation activities. Federal regulations emphasize safety and security; the SWTP will look carefully at the safety and security of different transportation modes.

How can I participate in the SWTP update?

The study will have ample opportunity for citizens to participate through public meetings, reviewing materials on the web and providing comments. You can send in comments via mail, e-mail, or in person at meetings. You can stay involved through materials posted to the web, by attending public meetings and by communicating with the study team.

How does the State include Indian Trides in the statewide planning process?

The FAST Act and FHWA continue to strengthen the role of Indian Tribes in the transportation planning process. Transportation plans shall be developed in consultation with the tribal government and the Secretary of the Interior. FHWA recently convened a rulemaking committee for the Tribal Transportation Self-Governance Program (TTSGP) in order to develop a detailed interpretation of how and when Indian Tribes should be fully involved in federal processes and programs. In the meantime, ALDOT is continuing its efforts towards more fully incorporating the Indian Tribes into its planning processes. For the Statewide Transportation Plan, ALDOT is coordinating to receive relevant transportation and socioeconomic data and information, particularly with regard to travel demand modeling and projected growth.

The State of Alabama recognizes nine Indian Tribes: Poarch Band of Creek Indians, Echota Cherokee Tribe of Alabama, Cherokee Tribe of Northeast Alabama, Ma-Chis Lower Creek Indian Tribe of Alabama, Southeastern Mvskoke Nation, Cher-O-Creek Intra Tribal Indians, MOWA Band of Choctaw Indians, Piqua Shawnee Tribe, and United Cherokee Ani-Yun-Wiya Nation. One is also federally recognized: the Poarch Band of Creek Indians.

How are the Statewide Transportation Plan and the Statewide Transportation Improvement Program related?

The Statewide Transportation Plan is a long-range planning document looking 20 years or more into the future. The Statewide Transportation Plan is not required to include specific projects but will provide a plan to improve and maintain the State’s current assets. The Statewide Transportation Improvement Program (STIP) identifies multimodal transportation projects across the state for a four year period. The STIP includes all projects inside the Metropolitan Planning Organization’s TIP, as well as projects in the rural and small urban areas. The STIP is financially constrained, meaning there are sufficient funds available to complete the four-year program of projects.

What is a Statewide Travel Demand Model?

A statewide model will be developed to provide projected traffic volumes, as well as to identify anticipated locations of congestion and need for improvements. The model reflects base year 2010 and future year 2040 growth and is based on readily available data. The model platform is CUBE Voyager.

The model process is initiated with assessment of current conditions. Traffic Analysis Zone (TAZ) boundaries are defined through a review of Census data, MPO models, and previous ALDOT evaluations of transportation conditions. The trip generation module uses base year socioeconomic data (population, households, employment, household median income, and automobile ownership) to determine the number of trips made between TAZs.

Following development of the trip generation module, a base year roadway network will be developed to include all Interstates, U.S. Routes, and State Routes. Trips are assigned to the network based on the simplest path between an origin and a destination. By running the base year model, an estimate of the total number of vehicles using each roadway in the network will be developed. When compared to the roadway capacity, the model identifies congested areas and shows the level of congestion projected to occur.

The base year model is calibrated and validated to FHWA specifications provided in the Model Calibration and Reasonableness Checking Manual. Calibration and validation of the base year model ensures it accurately reflects current travel patterns and traffic volumes, thereby providing confidence in the model and its ability to reflect current as well as future conditions. After approval of the base year model, the future year model is developed to project future conditions and determine the transportation network’s future performance.

Mapping
Statewide Network

This map depicts the highway network that will be used for the Alabama Statewide Transportation Plan. This network will consist of all interstates, U.S. routes, and state routes running through Alabama. This network will allow for a macro-level assessment and forecast of traffic across the State.

National Highway System

The National Highway System is a result of the National Highway System Designation Act of 1995. It is a network of strategic highways within the United States, serving major airports, ports, railway stations, and similar facilities.

Primary Highway Freight System

This map depicts the Primary Highway Freight System component of the National Highway Freight Network. This network was created by the USDOT under MAP-21 legislation and revised under the FAST Act as a means of representing significant freight movements.

Statewide Primary Freight Network

Expands upon the Primary Highway Freight System to include the major highways and other important corridors for freight movement in the state. The Statewide Primary Freight Network includes I-59 and the completed I-22, as well as State Route 113 which serves as a link to the greater Pensacola, FL area. More information on the Statewide Primary Freight Network can be found in the Alabama Statewide Freight Plan.

Draft Multimodal Freight Network

This map was developed by the U.S. DOT as part of their National Freight Strategic Plan. The map depicts airports, ports, rail connectors, railways, marine highways, and highways of significance. More information, including the methodology, can be found in the National Freight Strategic Plan.

STRAHNET

Depicts the Alabama portion of the United States Strategic Highway Network (STRAHNET). The STRAHNET is a 62,791 mile system of roads used to support U.S. military operations. 1,945 of those miles are located in the State of Alabama and provide access to locations such as Redstone Arsenal, Maxwell Air Force Base, and Fort Rucker.


Ports, Airports, and Intermodal Facilities

The ability to safely and efficiently move goods across the state is an essential function of the transportation system. Alabama’s ports and airports move goods and services into and out of the state, as well as the country, and interact with the highway and rail systems through numerous intermodal centers.

State Railway Network

Alabama has an extensive railway network, used to move both passengers and freight. There are four Class I Railroads in Alabama, and only one Class II Railroad. This map includes both Class I and Class II Railroads, as well as the 27 Class III Railroads, also known as Short Line Railroads.

Fixed Route Transit Locations

Legislation authorizes the FTA to make funds available on an annual basis to public agencies around the country to provide transit services. This map shows where fixed route transit locations are located across Alabama.

Intercity Bus and Rail Routes

5311f funds are used by ALDOT to support intercity bus services in Alabama. This map displays intercity bus routes across the state.

Bridges and Sufficiency Ratings

Bridges are scheduled for rehabilitation or replacement based on a sufficiency rating. This map displays the level of sufficiency for bridges in Alabama. Ratings are determined from the bridge inspection, traffic counts, the age of the bridge, and other factors.

Pavement Condition

ALDOT’s Pavement Management Section supports the Department’s pavement management system through the collection of data, management of the database, and management of reporting activities.

Statewide Bicycle and Pedestrian Plan

The Alabama Department of Transportation is in the process of updating the Statewide Bicycle and Pedestrian Plan. The purpose of the plan is to guide investments in bicycle and pedestrian facilities.


Functional Classification

Roadways are described by the federal functional classification system, which defines a roadway based on its accessibility and mobility. On one end of the spectrum are expressways or interstates, which provide the greatest mobility but the least accessibility. On the other end are local roads, providing the greatest accessibility but the least mobility.

Existing Traffic Volumes

Traffic volumes are collected by the Alabama Department of Transportation. ALDOT’s Traffic Section uses ATRS, electronic strips, and other technology, along with manual counts, to determine daily and hourly traffic. ALDOT makes this information available to the public via their website.

Existing Congestion

FHWA defines a bottleneck as a localized section of highway that experiences reduced speeds and inherent delays due to a recurring operational influence or a nonrecurring impacting event. The below maps reflect bottlenecks in a number of the urbanized areas.

Birmingham Chokepoints
Montgomery Chokepoints
Huntsville Chokepoints
Mobile Chokepoints
Auburn Chokepoints
Decatur Chokepoints
Dothan Chokepoints
Orange Beach Chokepoints
Tuscaloosa Chokepoints
Projected Traffic Volumes

Traffic Volumes are projected using a travel demand model. ALDOT currently uses CUBE Voyager to develop a base model and project that traffic out to the year 2040. More information about travel demand modeling can be found in the Frequently Asked Questions section.

Projected Congestion

Projected congestion is dependent on a number of factors, including the movement of the residential population and the rise and fall of employment centers. This map will show projected 2040 congestion based on the 2040 travel demand model.
