Traffic flow at a rate of 1200 veh/hr and density of 20 veh/km joined the tail of a 400 m-long Santacruzan procession moving at a pace of 3 kph. Since it was impossible to pass, a platoon density of 190 veh/km was formed. The head of the procession was expected to exit the road after moving 1 km. The capacity of the road is 2000 veh/hr at density 45 veh/km and jam density is at 200 veh/km. a. Draw approximately the − diagram to show the computation of shock wave. b. Estimate the length of queue after the Santacruzan procession has cleared the road. c. Estimate how long it would take to disperse the platoon queue.

Question
Traffic flow at a rate of 1200 veh/hr and density of 20 veh/km joined the tail of a 400 m-long
Santacruzan procession moving at a pace of 3 kph. Since it was impossible to pass, a platoon density
of 190 veh/km was formed. The head of the procession was expected to exit the road after moving 1
km. The capacity of the road is 2000 veh/hr at density 45 veh/km and jam density is at 200 veh/km.
a. Draw approximately the − diagram to show the computation of shock wave.
b. Estimate the length of queue after the Santacruzan procession has cleared the road.
c. Estimate how long it would take to disperse the platoon queue.
