CHARLESTON TRAFFIC SYSTEM CAPTURES WORLDWIDE ATTENTION

THE NEW SYSTEM INSTALLED BY THE LFE CORPORATION INCORPORATES SEVERAL IMPORTANT TECHNICAL FEATURES WHICH ARE EXPECTED TO INCREASE DOWNTOWN ROADWAY CAPACITY BY 15 PERCENT. BASED ON A TRAFFIC-RESPONSIVE CONCEPT, THE CONSTANTLY CHANGING NEEDS OF TRAFFIC DICTATE THE SIGNAL OPERATION. SOME OF THE INTERESTING SUBSYSTEMS INCLUDE: (1) A FIRE-RUN SYSTEM WHICH ALLOWS A CONTROLLER AT THE FIRE DEPARTMENT TO PUSH A BUTTON AND GIVE A FIRE TRUCK THE GREEN LIGHT ALL THE WAY TO THE FIRE. (2) ITS OWN TELEPHONE SYSTEM ENABLES A MAN WORKING AT ONE OF THE INTERSECTION CONTROL BOXES TO TALK DIRECTLY TO THE CENTER WHILE WORKING AT THE BOX. (3) CLOSED CIRCUIT TV ALLOWS FIVE CRUCIAL TRAFFIC SPOTS TO BE MONITORED WHILE DISPLAY MAPS SHOW THE STATE OF EACH INTERSECTION. (4) THE SYSTEM IS SO EFFICIENT THAT IT NOT ONLY REPORTS ON ITSELF IF THERE IS TROUBLE, IT CALLS A TECHNICIAN AT HOME IF THE TROUBLE OCCURS AT NIGHT. (5) THE SYSTEM COLLECTS DATA FOR LONG-TERM PLANNING AND RESEARCH PROJECTS, AND AT THE SAME TIME PROVIDES A RUNNING CHECK ON SYSTEM OPERATION. /ASCE/
