- 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. [4 pts] (e) Check the expected LOS for 2-directional lanes on this freeway segment. [4 pts]arrow_forwardObserving a deterministic queue in 3 hours, suppose vehicles arrive at a rate of 500 vph for the first hour and 150 vph for the second and third hours. The service rate is 150 vph for the first two hours. The server can discharge 500 vehicles for the last hour. (a) What is the queue length after 30 minutes? [4 pts] (b) What is the maximum queue length? [4 pts] (c) When does the maximum queue happen? [4 pts] (d) What is the total delay? [4 pts] (e) Describe how the queue grows and discharges in this queuing process. [4 pts]arrow_forward

CIVIL ENGINEERING ROANTICLO (Earthworks Quantities) (Due Date: Friday, 28/03/2025) Done Thumbi Irrigation Scheme in Mzimba district is under threat of flooding. In order to mitigate against the problem, authorities have decided to construct a flood protection bund (Dyke). Figure 1 is a cross section of a 300m long proposed dyke; together with its foundation (key). Survey data for the proposed site of the dyke are presented in Table 1. Table 2 provides swelling and shrinkage factors for the fill material that has been proposed. The dyke dimensions that are given are for a compacted fill. (1) Assume you are in the design office, use both the Simpson Rule and Trapezoidal Rule to compute the total volume of earthworks required. (Assume both the dyke and the key will use the same material). (2) If you are a Contractor, how many days will it take to finish hauling the computed earthworks using 3 tippers of 12m³ each? Make appropriate assumptions.…arrow_forwardThumbi Irrigation Scheme in Mzimba district is under threat of flooding.
