Question: Prove that the maximum flow using Greenberg Model can be computed using the following formula: q m a x = u f * k j

Prove that the maximum flow using Greenberg Model can be computed using the following
formula:
qmax=uf*kje1
A freeway with two lanes in one direction has a capacity of 2,100vehh?ln under normal
operation (i.e., under saturation). One of these lanes is blocked for 15 minutes on a particular
morning, beginning at 7:00 AM. The queue discharge capacity (capacity under unstable
traffic conditions) is only 1,950vehhrln. The arrival pattern of vehicles at this location is as
follows:
Conduct a deterministic queuing analysis to determine:
a. The maximum size and length of the queue, assuming the average distance occupied
by vehicle is 50ft? vehicle
b. The time that the queue will fully dissipate
Using a linear car-following model, simulate the movement of two vehicles under the
following conditions:
The two cars were initially moving at a uniform speed of 60kmhr, with the driver in
the following car attempting to maintain a safe distance of 30 m .
The driver in the lead car rapidly decelerated at the rate of 4.5ms2 for 2 sec .
The reaction time in the following vehicle equals 0.8 sec .
