Q2: What are the assumptions for using the equations in the queue test? Q3: A signalized intersection, of 105 sec cycle length, the east approach has an effective green time of 20 sec, and the percentage of vehicles arriving during green time is 28%. The west approach has 16 sec green time and 32% of vehicles arriving during the green time. Determine which approach is best coordinated with the upstream signal.

Subject: transportation engineering Read the question carefully and give me right solution according to the question. A signal has four phases, where the critical lane group flow ratios are 0.115, 0.204, 0.099, and 0.248. If the lost time per phase is 6 seconds and the critical intersection v/c ratio is 0.88, calculate the minimum cycle length and the phase effective green times such that the lane group v/c ratios are equal.
Question- A signalized intersection operates in two phases. The lost time is 3 seconds per phases. The maximum ratios of approach flow to saturation flow for the two phases are 0.37 and 0.40. The optimum cycle length using the Webster's method (in seconds, round off to one decimal place) is...
