1.Draw a space–time diagram for how shock waves form in a tunnel?

2
You were the driver of the sixth vehicle to be stopped by a red light at a signalized intersection. Ten seconds elapsed after the onset of the green light for your approach before you were able to start moving. Given the release flow was 1200veh/hr, calculate the release concentration and the release mean speed assuming an average car length of 5.5m and a clearance between cars of 0.60m
