In Problem 7.1, the following additional information is known: the lost time per phase is 5 seconds, there are two lanes for N/S through and right turn traffic, one lane in each of the other traffic movements shown in Table 7.6 (the table for Problem 7.1). Each lane is 12 ft wide, and the approaching speed for E/W street is 30 ft/s while that for N/S street is 20 ft/s. The width of all the crosswalks at that intersection is 10 ft wide, and there are typically 10 pedestrians crossing either street in any one phase. (d) Using the timing value after pedestrian green time check, compute: i. The average delay per movement. ii. The average delay per phase. iii. The overall intersection delay. iv. Determine the level of service per phase and for overall intersection.
