Models of Traffic Flow (Section 5.4)
5.7 An observer has determined that the time
headways between successive vehicles on a section of
highway are exponentially distributed and that 65%
of the headways between vehicles are 9 seconds or
greater. If the observer decides to count traffic in 30-
second time intervals, estimate the probability of the
observer counting exactly four vehicles in an interval.
5.8 At a specified point on a highway vehicles are
7.2 An intersection has a four-timing-stage signal
with the movements allowed in each timing stage
and corresponding analysis and saturation flow
rates shown in Table 7.7. Calculate the sum of the
flow ratios for the critical lane groups.
5.27 At a parking lot, vehicles arrive according to a
Poisson process and are processed (parking fee
collected) at a uniform deterministic rate at a single
station. The mean arrival rate is 4.2 veh/min and the
processing rate is 5 veh/min. Determine the average
length of queue, the average time spent in the system,
and the average waiting time in the queue.
5.28 Consider the parking lot and conditions
described in Problem 5.27. If the rate at which vehicles
are processed became exponentially distributed
(instead of deterministic) with a mean processing rate
of 5 veh/min, what would be the average length of
queue, the average time spent in the system, and the
average waiting time in the queue?
