EVALUATION OF OFF-LINE TRAFFIC-SIGNAL OPTIMIZATION TECHNIQUES
Four off-line traffic-signal optimization techniques (SIGOP, TRANSYT, Combination Method, and a preferential- street program that is SIGRID-BASED) were evaluated in both a suburban area and central area network environment within metropolitan Toronto. For each network, fixed-time and time-of-day signal timing patterns were developed for the 7:00 a.m. to 9:00 a.m., 10:00 a.m. to 12:00 noon, 1:00 p.m. to 3:00 p.m., and 4:00 p.m. to 6:00 p.m. time periods. To evaluate the various timing patterns, network travel time, and delay, researches collected stop and volume data over a 12-week period in the fall of 1973. These data served as the base for a series of comprehensive statistical analyses oriented primarily toward a network evaluation of travel time and service rate. The data later were evaluated by a link-by-link paired comparison analysis. The network analysis to travel time and service rate did not provide conclusive results of the nature of the study data. On the other hand, the link-by-link paired comparison analyses were more conclusive, relatively simple to use, and easy to interpret. Although the Combination Method settings provided Toronto motorists with a slightly better on-street performance level, any 1 of the 4 methods can provide reasonable signal-network settings.
