"MOTORCALL" HIGHWAY EMERGENCY RADIO SYSTEM INTRODUCED AT IACP
A WATERPROOF TWO-WAY COMMUNICATION SYSTEM FOR USE BY MOTORISTS STRANDED ON LIMITED ACCESS HIGHWAY HAS BEEN DESIGNED BY THE MOTOROLA CORP. INSTALLED IN CALL BOXES ALONG THE ROADSIDE, THE TWO-WAY RADIO IS ACTUATED WHEN THE MOTORIST REMOVES THE HANDSET FROM THE BOX. A DISPATCHER AT A CENTRAL LOCATION AUTOMATICALLY RECEIVES A POSITION FIX AND DISPLAY, AND AFTER RECEIVING THE MOTORIST'S DESCRIPTION OF THE PROBLEM CAN TAKE APPROPRIATE ACTION. THE SOLID STATE UNIT IN THE CALL BOX HAS BUILT-IN CONTROLS TO SIGNAL OPERATING CONDITION AND TO SOUND AN ALERT TO THE DISPATCHER SHOULD IT BE TAMPERED WITH. THE AUTOMATIC FEATURES OF THE SYSTEM ASSURE ACCURATE PIPPOINTING OF HIGHWAY EMERGENCIES AND OBVIATE THE NEED FOR REGULAR MAINTENANCE.
