The three major elements of TravTek are the TravTek Information and Services Center (TISC), the TravTek vehicles and the Traffic Management Center (TMC). The Federal Highway Administration (FHWA) has issued a contract to design and implement the TMC and a network of agencies and companies that will supply traffic information and data. These sources of information and the TravTek vehicles are known as the Traffic Information Network (TIN). The TIN sends this information to the TMC which combines and processes it to generate reports in a process known as data fusion. Historical data and operator-entered information are also included in the data fusion process to generate the various status, incident, and link data reports. The TMC facilitates and pursues incident and congestion confirmation and clearance information from the TIN sources, fuses the information and provides it in the form of a computerized report to various users. Only data pertaining to link travel times and confirmed incidents or congestion are provided to the TravTek vehicles and to other end users.
