Two traffic signals are timed with the settings below. The posted speed is 25 mph and the signals are 300 feet apart (north-south direction). Assume 4 second yd low and 1 second red clearance time (all movements). Assume phase 2 is the southbound phase similar to the Signal Timing Manual The offset reference point is start of 2 & 6 Yellow. Show the time space diagram for this system. Feel free to use graph paper or sketch to scale if you think it will be helpful. Show ring barrier structure or circle diagram based on timing. Describe bandwidth for these signals. Describe the optimal offset for this system of two intersections based on a manual assessment of the information given
