Samenvatting

The two principal objectives of the research were (1) to test and compare computer simulations of traffic signal systems,and to make field verifications;and (2) to verify the ability of computer simulation methods to predict accurately the effects of signal timing modifications. A variety of methods were employed in different combinations.two grid networks were used as test sites: a 26-intersection site in los angeles (peak hour flows, 175-1475) and a 22-intersection site in san jose (peak hour flows,250-1200).in los angeles,the peak and off-peak increases in average network speed were 17-24 and 18-22%,respectively.in san jose,where the existing system is operated by an ibm 1800 traffic control computer using a library of strategic timing plans,the increase for the best timing plan was about 5%.
