An approach to a signalized intersection has a saturation flow rate of 1800 veh/h. At the beginning of an effective red, there are 6 vehicles in queue and vehicles arrive at a rate of 900 veh/h. The signal has a 60-second cycle with 25 seconds of effective red. What is the total vehicle delay after one cycle?

Consider a freeway with two lanes and capacity of 2000 veh/h/lane, jam density of 60 veh/km/lane and a triangular fundamental diagram. Traffic is moving with the flow of 3000 veh/h and the space mean speed of 100 km/h. At 10:00 a.m., a traffic crash occurs that blocks one lane for half an hour. Using shockwave analysis, answer the following questions. a. Draw the space-time diagram with shockwaves and traffic states (trajectories not needed). [2 marks] b. At time t =...
