POTENTIAL USES OF VARIABLE-MESSAGE SIGNS IN NEW YORK CITY

AS A RESULT OF THE MODERNIZATION PROGRAM INITIATED AT THE NEW YORK CITY DEPARTMENT OF TRAFFIC IN 1950, A COMPUTERIZED TRAFFIC SIGNAL CONTROL SYSTEM IS PROPOSED FOR 7,000 SIGNALIZED INTERSECTIONS AND 4,500 SYSTEM SENSORS. AT THE PRESENT TIME, ONE COMPUTER CONTROLS 450 INTERSECTIONS ON 8 ARTERIALS IN THE BOROUGH OF QUEENS. MORE EFFECTIVE VARIABLE MESSAGE SIGNING POSSIBILITIES ARE ANTICIPATED WITH THE CONTINUED EXPANSION OF THE COMPUTERIZED SYSTEM, SINCE ON-STREET SENSORS WITH THE CLOSED-LOOP FEED BACK WILL BE AVAILABLE FOR DIRECTING MOTORISTS. DESIGN FEATURES INCORPORATING LUMINATION SOURCE, VANDAL-RESISTANCE, EASY MAINTENANCE, VISIBILITY, AND COST LIMITATIONS OF VARIABLE MESSAGE SIGNS MUST BE USED AND COORDINATED WITH OTHER TRAFFIC CONTROL DEVICES. THIS DISCUSSION ALSO INCLUDES CHANGEABLE MESSAGE SIGNS FOR CONTROLLING PEDESTRIAN TRAFFIC; INCANDESCENT LIGHTING IS REPLACING NEON GRIDS AND TRANSFORMERS.
