Traffic moving on the roadway at a density of 30 veh/mile is stopped for 30 seconds at a red traffic signal. After this red time, a green time of G seconds is provided to clear traffic. After which, the traffic signal returns to 30 seconds of red, and so on in a cyclic manner. Determine the minimum green time G needed so that the queue will not grow from cycle to cycle (the stopped flow’s density is jam density and the release traffic moves at the capacity of the roadway). v QUESTION 2. A bus system consisting of 50 buses (50-seaters) charges $1.00 per ride (currently, the buses are fully utilized). It has been decided to put 10% more buses into service.
