EVALUATION OF COMMERCIAL RADIO FOR REAL-TIME DRIVER COMMUNICATIONS ON URBAN FREEWAYS

DRIVER PREFERENCES WERE MEASURED THROUGH A QUESTIONNAIRE SURVEY TO EVALUATE THE POTENTIAL OF COMMERCIAL RADIO FOR PROVIDING REAL-TIME FREEWAY TRAFFIC INFORMATION TO DRIVERS IN URBAN AREAS. IN ADDITION, TRAFFIC REPORTS GIVEN BY 3 RADIO STATIONS IN THE HOUSTON AREA WERE MONITORED TO EVALUATE THE RELIABILITY, ACCURACY, AND TIMELINESS OF CURRENT TRAFFIC BROADCASTS. THE RESULTS OF THE STUDY SUGGEST THAT COMMERCIAL RADIO COULD PLAY AN IMPORTANT ROLE AS PART OF AN EFFECTIVE REAL-TIME TRAFFIC INFORMATION SYSTEM FOR URBAN FREEWAY DRIVERS. THERE DID NOT APPEAR TO BE ANY APPRECIABLE DIFFERENCE BETWEEN THE PREFERENCE FOR RADIO AND THE PREFERENCE FOR CHANGEABLE MESSAGE SIGNS. TRAFFIC REPORTS AS CURRENTLY BROADCAST BY THE 3 RADIO STATIONS MONITORED IN HOUSTON WOULD NOT BE COMPLETELY SATISFACTORY FOR THE SYSTEM BEING CONSIDERED. IMPROVEMENTS IN THE RELIABILITY AND TIMELINESS OF THE TRAFFIC INFORMATION PROVIDED WOULD BE NECESSARY.
