Question

One section of an arterial street includes three intersections with a speed limit of 40 mph and a common cycle time of 80 seconds.

a. The signal offset of the 1st intersection is set at 20 sec and its green time is 35 sec. The distance between the 1st and 2nd intersections is 450 feet, for coordinating the two intersections what should be the offset for 2nd intersection?

b. The distance from the 2nd intersection and 3rd intersection is 240 feet. If we want to start the green signals for these two intersections at the same time in each cycle, at least how long should the green time be set at the 3rd intersection to obtain a minimum green bandwidth of 25 sec?

Answer 1

ANSWER:---

MPH:--- METER PER HOUR.
