Unformatted text preview: Homework #6: Actuated Traffic Signal Design and Coordination Problem 1 Consider the intersection of University and California shown in Figure 1. The major street (University) is 80-feet wide; the minor street (California) is 50-feet wide. Lane markings are shown as in the figure. Extension detectors are located 120-feet upstream of the stopline on University; there are no upstream extension detectors on California. There are stopline detectors on the THRU lanes on University, and on all lanes of California. The left turn bays on University contain 80-feet presence loop detectors. The signal controller is a Type 170 actuated controller. Pedestrian traffic is light to moderate. Assume the Walk time is 4 seconds. Traffic data for the morning peak are displayed in Table 1. 80 ft 50 ft University 45 mph 45 mph 30 mph California Median Presence detector 80 ft 120 ft 120 ft Extension detector Extension detector N 80 ft 50 ft University 45 mph 45 mph 30 mph California Median Presence detector 80 ft 120 ft 120 ft Extension detector Extension detector N Figure 1.
