TEXAS'S PEGASUS AND TRIAD - PLANNING FOR TOMORROW'S TRANSPORTATION NEEDS

The design of freeway and street traffic control, surveillance, or motorist information system must provide for public transportation and high-occupancy vehicle needs, as well as consider future developements such as intelligent vehicle/highway systems. The PEGASUS and Traffic Management Triad systems are such systems. The PEGASUS (People, Goods, And Services Urban System) incorporates future area wide demand-responsive and route guidance systems into the traffic-responsive system. It is a distributive system and is modular in design (HOV lane, freeway mainlane, and frontage road, plus street system modules). Currently being developed in Texas, it will be installed in coordination with the reconstruction of most urban freeways in Texas over the next 10 years. Texas has also set up a Traffic Management Triad to improve and lower the costs of transportation systems. It provides a means for organizing the traffic management work within a city, and it consists of 3 components: transportation system design improvements, active traffic management; and traffic management team.
