Update on the Michigan DIRECT operational field test

Two of the most essential features of the Michigan DIRECT (Driver Information Radio Utilising Experimental Communication Technologies) operational field test are simplicity of design and low cost to the motorist. The test has a focus on the in-vehicle receivers for real time driver information and with relatively limited in-vehicle processing. Additionally, there is no infrastructure expansion cost, as the existing ATMS equipment is proposed to be used for the test. The primary goal of the project is to evaluate the user benefits, institutional issues and technical issues of enroute driver advisory and traveler information services in an operational setting. The emphasis is on the testing and evaluation of voice-based communication systems that can offer: (a) basic services at a minimal incremental cost to the traveler; and (b) a high potential for operational deployment
