SUMMARY

Synopsis of Bill

House Memorial 45 requests that the city of Santa Fe be requested to set traffic signal for better

coordination to maintain traffic at a continuous speed.

SIGNIFICANT ISSUES

Research indicates that the coordination of traffic signals to facilitate smooth traffic flow

(progressed movement) along a street is a proven technique. The quality of the resulting

progression is a function of the spacing of the signals, the prevailing speed, and the amount of

traffic coming in and out of driveways between traffic signals, the uniformity of intersection

sizes, and the traffic signal cycle length. The traffic volume and the proportion of the green time

given to the preferred movements are also important. The goal of coordination is to get the

greatest number of vehicles through the system with the fewest stops in a comfortable manner.
