- A toll booth on the Thruway experiences an average inter-arrival time of 3 minutes between each vehicle. As an operator, you want to have a mean queue length of at most 2 vehicles. What mean service rate (per hour) will the toll booth need to provide?arrow_forwardA freeway is to be designed at a location on level terrain for an annual average daily traffic (AADT) of 45,000 vehicles per day. For a conversion of AADT to an annual hourly volume, assume that the K-factor is 0.10 (i.e., the 30th highest hourly volume of the year). In addition, 55% of the peak-hour traffic volume is expected to travel in the peak direction (D = 0.55). This freeway segment will be for regular commuters. Other estimates include: PHF of 0.95, free-flow speed of 65 mph, and 20% trucks of the traffic stream. In order to determine the number of lanes required to provide at least LOS C, answer the following questions. (a) Determine Free Flow Speed (FFS) [4 pts] (b) Find the directional design-hour volume (DDHV) [4 pts] (c) Find fHv [4 pts] (d) Determine the number of lanes required.
