EVALUATION OF TRAFFIC SIGNAL CONTROL SYSTEMS
The need for increased efficiency in traffic management has given rise to improved traffic signal control using digital computer and microprocessor technology. Signal control is defined (phasing, cycle length, split, and offset) and the difference between "old" and "new" systems is explained. The effectiveness of the newer systems is highlighted; they provide an average 15% improved street performance and a five-to-one payback in one year (25-to-one for the system life). Annual nationwide savings are estimated at 375 million gallons of fuel and 624 million hours of travel time. The fuel savings are in addition to those resulting from vehicle downsizing and fuel efficiency. Other benefits of computer-based traffic control are quick reporting of system failure and evaluation of system performance.
