Concept
Transportation in Texas
Résumé
The Texas Department of Transportation (TxDOT) is a governmental agency and its purpose is to "provide safe, effective, and efficient movement of people and goods" throughout the state. Though the public face of the agency is generally associated with maintenance of the state's immense highway system, the agency is also responsible for aviation in the state and overseeing public transportation systems.
Texas state highways
Texas freeways have
on heavily traveled since their 1948 beginnings with a several-mile stretch of Houston's Gulf Freeway, and are often under construction to meet the demands of continuing growth. As of 2005, there were of public highway in Texas (up from in 1984). Texas Department of Transportation (TxDOT) planners have sought ways to reduce rush hour congestion, primarily through High-occupancy vehicle (HOV) lanes for vans and carpools. The "Texas T", an innovation originally introduced in Houston, is a ramp design that allows vehicles in the HOV lane, which is usually the center lane, to exit directly to transit centers or to enter the freeway directly into the HOV lane without crossing multiple lanes of traffic. Timed freeway entrances, which regulate the addition of cars to the freeway, are also common. Houston and San Antonio have extensive networks of freeway cameras linked to transit control centers to monitor and study traffic.
One characteristic of Texas's freeways are its frontage roads (also known as service roads, feeder roads, and access roads). Texas is the only state that widely constructs frontage/access roads along its highways even in the most remote areas.Frontage Roads - What are Frontage Roads and Why Does Texas Have So Many? Frontage roads provide access to the freeway from businesses alongside, such as gas stations and retail stores, and vice versa. Alongside most freeways along with the frontage roads are two to four lanes in each direction parallel to the freeway permitting easy access to individual city streets.
