7) In studying of traffic flow at a highway toll booth over a course of 60 minutes, it is determined that the arrival and departure rates are deterministic, but not uniform. The arrival rate is found to vary according to the function A(t) = 1 .8 +0.25t - 0.00312. The departure rate function is u(t) = 1.4+0 .1lt. In both of these functions, t is in minutes after the beginning of the observation and (t) and „u(t) are in vehicles per minute. At what time does the maximum queue length occur? a) 49.4 min, b) 2.7 min ,c) 19.4 min, d) 60.0 min

Concept explainers

Capacity and Level of Service at Intersections

The term capacity is associated with transportation engineering. Capacity helps to understand how many pedestrians or vehicles can be handled by a transport facility. Level of service is also a term associated with transportation engineering. The level of service indicates the performance of the transport facility.

Question

7) In studying of traffic flow at a highway toll booth over a course of 60 minutes, it is determined that
the arrival and departure rates are deterministic, but not uniform. The arrival rate is found to vary
according to the function A(t) = 1.8+0.25t - 0.00312. The departure rate function is u(t) = 1.4 +0
.1lt. In both of these functions, t is in minutes after the beginning of the observation and (t) and
„u(t) are in vehicles per minute. At what time does the maximum queue length occur?
a) 49.4 min, b) 2.7 min ,c) 19.4 min, d) 60.0 min

A researcher was observing traffic along one lane of a rural highway. During a 1 minute time interval, ten vehicles were observed travelling 65, 64, 71, 66, 58, 72, 69, 66, 55 and 62 mph. Estimate the average vehicle spacing (ft/veh). Provide your answer to the nearest integer.
The following travel times are measured for vehicles as they cross the highway 2.0 miles long. Calculate time average speed (TMS) and average speed space (SMS) for this data. Why is SMS always lower than TMS?
