Traffic signals can be synchronized so that a car, starting at one end of a street and traveling at preassigned speeds, can go to the other end without stopping for a red lightoThe portiong of a signal cycle for which this is possible is called the bandwidth for that direction.Ordinarily the bandwidth in each direction is single i.eo is not split into two or more intervals within a cycle. Two problems are solved for this caa..(a)gi..n an arbitrary number of signal. along a street,a common cycle length,the green and red times for each signal,and specified vehicle speeds in each direc. tion between adjacent signals,synchroncze the signals to producr bandwidths that ar} equal in each direction and as large as pos- sible and (b) ad,~ust the synchronization to increase one band- width to some specified,feasible value and maintain the other as large as is then possible.The method of calculations has been programmed for a 20K IBM 1620
