The results of introduction of congestion alleviation control which is the main function of STREAM at 308 critical intersections within Tokyo showed that total travel time during the daytime (7 a.m. to 7 p.m.) fell by 9 percent, total delay fell by 23 percent and congestion length-time fell by 28 percent. The result in economic terms was an annual saving of at least 100 billion yen. From these results we confirmed that STREAM is effective in reducing congestion and that during congested conditions at the above 308 intersections, competing traffic flows are handled more equally than in the previous control system.
