A STUDY OF THE FEASIBILITY OF USING ROADSIDE RADIO COMMUNICATIONS FOR TRAFFIC CONTROL AND DRIVER INFORMATION

THE EFFECTIVENESS OF A NEW METHOD OF ROADWAY COMMUNICATION WITH THE DRIVER WHICH INCORPORATES CAR MOUNTED RECEIVERS AND ROADSIDE TRANSMITTER INSTALLATIONS WAS MEASURED AS A TRAFFIC CONTROL AND DRIVER INFORMATION DEVICE. TO JUDGE ITS ACCEPTABILITY BY THE DRIVING PUBLIC AND TO ARRIVE AT A PRELIMINARY COST FOR THE IMPLEMENTATION OF SUCH A SYSTEM, ONE HALF OF THE VEHICLES SELECTED WERE USED AS TEST GROUP AND HALF AS CONTROL GROUP FOR EACH OF THREE EXPERIMENTS IN WHICH THE TEST GROUP DRIVERS RECEIVED INFORMATION ON ACCIDENTS AND TYPICAL MAINTENANCE ACTIVITIES. IN THE ROUTE INFORMATION EXPERIMENT NO CONTROL GROUP WAS USED. BOTH TEST AND CONTROL GROUP DRIVERS RECEIVED SIMILAR INFORMATION FROM SIGNS AND OTHER SIGNALS WHERE THEY WERE EMPLOYED. DATA ON TRAFFIC FLOW WERE COLLECTED USING TIME-LAPSE MOTION PICTURE PHOTOGRAPHY AT LOCATIONS JUST BEYOND THE POINTS OF INFORMATION RECEPTION. IN ADDITION, TEST VEHICLE OPERATORS WERE INTERVIEWED AT THE END OF 10 MILES OF THE TEST SECTION TO DETERMINE THEIR REACTION TO THE RADIO COMMUNICATION. RESULTS OF THE EXPERIMENT SHOWED THAT RADIO COMMUNICATION IS EFFECTIVE IN CONTROLLING VEHICLE SPEED IN HAZARDOUS AREAS. THE ROUTE INFORMATION GIVEN IN ONE OF THE EXPERIMENTS WAS CONSIDERED BY DRIVERS TO BE HELPFUL AND INDICATED A POSSIBLE FUTURE USE OF THE RADIO SYSTEM. INTERVIEW DATA REVEALED THAT THE MOTORISTS CONSIDERED RADIO COMMUNICATION USEFUL.
