Question 9 For a freeway with a free flow speed of 70 mph, and an analysis volume (or flow rate) of 1,906 passenger car/hour/lane, what is the speed in mph?
Suppose that a crash occurs on a two lane highway, blocking one lane for 45 minutes and dropping the capacity of the other lane by 70% for the same time period. After 45 minutes, the crash and emergency vehicles are cleared from the road and capacity of each lane returns to its normal value of 2000 vehicles/hour/lane. If vehicles approach the section at a rate of 2500 vehicles/hour and the queuing system can be assumed to be D/D/1: What is the length of the longest queue? vehicles How many minutes after the crash occurs does the queue clear? minutes
Vehicles arrive at an intersection at a rate of 450 veh/h according to a Poisson distribution. What is the probability that 3 or more vehicles will arrive in two successive 30-second interval?
A rural highway has one lane in each direction. In one direction V = 300 veh/hr/ln at a railroad crossing. The barriers at this crossing are lowered to block vehicles for four minutes and 30 seconds for a train to pass. What is the probability that when the barrier is lifted, the queue has exactly nine vehicles? Assume no initial queue.
A section of Texas Highway 83 (Tx83) has a free-flow speed of 55 mph and a capacity of 3,300 vehicles per hour. At 8 am, 2,100 vehicles were counted using a 6 ft by 6 ft inductive loop. If the linear speed-density relationship applies, what is the estimated space-mean speed of these vehicles?

On a highway, we know that on average 260 cars arrive at a toll booth in one hour. If we admit that thenumber of cars arriving at this toll station follows a lawPoisson, calculate the probability that there are less than fourarrived within a minute.
What is the probability that the headway between successive vehicles will be between 7 and11seconds if there is an average of 6 cars that passes the segment of the highway every minute?
2.) Daily Traffic Expansion Factors A student measured the traffic volume of a rural primary road for five hours on a Wednesday for a project. The data is summarized below: Time Volume 7:00 – 8:00 AM 200 8:00 – 9:00 AM 325 9:00 – 10:00 AM 410 10:00 – 11:00 AM 503 11:00 – 12:00 AM 385 a) Determine the 24-hour volume for that day. Unit: veh. /day b) Determine the average daily traffic for the week unit: veh. /day Listed/Shown in the images are the expansion factors given.
