QUESTION 6 10 points Save Answer On a queueing diagram, given the arrival and departure curves the length of the queue (in terms of number of vehicles) at any point can be measured by The horizontal distance between arrival and departure curves The vertical distance between arrival and departure curves O The integral of the departure rate (in vehicles per unit time) O The area between the arrival and departure curves QUESTION 7 10 points Save Answer Which of the following definitions define space-mean speed? O Time between passage of successive vehicles at some designated roadway point. Arithmetic mean of speeds of vehicles passing a designated point on a roadway during a specified time period O Average speed of vehicles occupying a given section of roadway over a specified time period O Number of vehicles traveling on a unit length of roadway at an instant in time QUESTION 8 10 points Save Answer A divided multilane highway in a recreational area has four lanes and is on rolling terrain. The highway has 10-ft lanes with a 6-ft right-side shoulder and a 3-ft left-side shoulder. The posted speed is 50 mi/h.
