Density on a corridor was estimated to be 47 vehicles per mile using a snapshot from a flying drone. If the average space mean speed was calculated as 45 mph, then what is the average headway between vehicles? Report your answer in seconds up to two digits after the decimal.
hree routes connect an origin and a destination with performance functions: ?1=8+0.5?1; ?2=1+2?2; and ?3=3+0.75?3; with the x’s being the traffic volume expressed in thousands of vehicles per hour and t’s being the travel time expressed in minutes. If the peak hour traffic demand is 3400 vehicles, determine user equilibrium traffic flows. [Hint: Note that one of the paths will not be used under the equilibrium condition
For this exercise, you are to design a roadway that is to carry 100,000 people a day (excluding truck occupants) – 50,000 in design direction. The vehicles that carry these people include; (1) personal vehicles (average occupancy of 1.2 people per car) 2-2 kip single axles, and (2) buses with 2-22 kip single axles (assume they are filled with an average of 40 passengers). There are also trucks on the roadway and all trucks have 1-40 kip triple axle, 1-32 kip tandem axle, and 1-8 kip single axle. You know that the soil CBR is 6, the initial PSI is 4.5 and the TSI is 2.5. Other values to be used:  All drainage coefficients = 1.0  Reliability = 90%  Overall standard deviation of traffic = 0.50  Concrete Modulus of Elasticity = 5.5 million lb/in2  Concrete Modulus of Rupture = 750 lb/in2  PCC load transfer coefficient = 3.0 Design a rigid and flexible pavement, to last 15 years, for a four-lane road (four lanes in design direction) with 400 trucks per day in the design direction, and…
Consider a simple transportation network that has one origin and one destination with two paths/links that provide access from the origin to the destination. One link is 9 miles long and has a capacity of 4800 vehicles per hour and a speed limit of 66 miles per hour. The other link is 6 miles long and has a capacity of 2400 vehicles per hour and a speed limit of 42 miles per hour. Assuming that 6000 drivers wish to make the trip from the origin to the destination, find the loaded network? a1 = 1.37904, b1 = 8.24124, a2 = 1.236, b2 = 6.2712

Drivers arrive at a toll booth at a rate of 5 per minute during peak traffic periods. The time between consecutive driver arrivals follows an exponential distribution. What is the probability that it will take a) more one minute between consecutive drivers? b) between 30 seconds and 90 seconds between consecutive drivers?
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?
13. An incident that occurs on a particular highway results in traffic incurring an average delay of one hour per vehicle. An estimated 2,000 vehicles are impacted by the incident. If the distribution of traffic is comprised of 5% five-axle trucks, 2% three-axle trucks, 4% six-tire trucks, 2% four-tire trucks, 4% medium auto for business purposes, 3% small auto for business purposes, and the remainder are automobiles for personal purposes, what is the value of the total delay incurred by the traffic.
