- Describe the following types of traffic volume counts and explain when they are used: 1. Cordon countsTwo routes are available to carry 1200 vehicles in peak-hour traffic. Route 1 has a posted speed limit of 45 mph and is 5 miles long. The travel time increases by 2x2, where x is vehicles in thousands. Route 2 has a limit of 55 mph and is 6.7 miles long, and the travel time increases by 1.5x. Find the user-equilibrium travel flow and travel time.The average queue length at the intersection of the two roads with a stop signs is 4 vehicles. If the arrival rate of vehicles at the stop sign is 300 vehicles per hour, determine the service rate of the road in vehicles per hour. Assume both arrival and departure rates are exponentially distributed.
- Describe the following types of traffic volume counts and explain when they are used: 1. Intersection counts(show your solutions) Given the figure above, compute for the Annual Average Daily Traffic of all vehicle types: * A.338 B.None of the above C.393 D.418 E.431hree 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
- The average of 24-hour traffic counts collected over a number of days greater than one but less than a year.The number of vehicles arriving at the upstream of a freeway bottleneck (free of queues) is shown in the table below. Based on the numbers given in the table, determine: (1) Bottleneck capacity in vehicles per hour (vph) (2) Downstream measured flow rate in the third time interval (3) The demand during the third time interval (4) Queue length at the end of the third and fourth intervalsDescribe the following types of traffic volume counts and explain when they are used: 1. Control counts
