The The buses will have 42 seats and up to 10 standing spaces. The following assumptions are made: . Boarding time is 5.5 sec per passenger. . If standees are present, boarding time increases by 40%. . Alighting time is 3.5 sec per passenger. . The time taken for doors to open and close is 4.0 sec. Table 1: Number of passengers boarding and alighting at the proposed stops Bus Stop 1 2 3 4 Number of Passengers Boarding 40 22 16 0 Alighting 0 14 24 40 (a) Calculate the dwell time for each bus stop. (b) Determine the coefficient of variation of dwell times. (c) Estimate the failure rate for the critical bus stop if the loading area capacity is 8 buses per hour, the clearance time is 10 seconds and the green time to cycle length ratio is 0.40.

plz, solve this question, it is not graded question. Transportation Engineering-1 Space Requirements for a Parking Garage The owner of a parking garage located in a CBD has observed that 22 percent of those wishing to park are turned back every day during the open hours 8 a.m. to 6 p.m. because of a lack of parking spaces. An analysis of data collected at the garage indicates that 65 percent of those who park are commuters, with an average parking duration of 9 hours, and the remaining percentage are shoppers, whose average parking duration is 2 hours. If 25 percent of those who cannot park are commuters and the rest are shoppers, and a total of 220 vehicles currently park daily in the garage (i.e. parking spaces are 220), determine the number of additional spaces required to meet the excess demand. Assume parking efficiency is 0.90.

[T] The following table provides hypothetical data regarding the level of service for a certain highway. Plot vehicles per hour per lane on the x-axis and highway speed on the y-axis. Compute the average decrease in speed (in miles per hour) per unit increase in congestion (vehicles per hour per lane) as the latter increases from 600 to 1000, from 1000 to 1500, and from 1500 to 2100. Does the decrease in miles per hour depend linearly on the increase in vehicles per hour per lane? Plot minutes per mile (60 times the reciprocal of miles per hour) as a function of vehicles per hour per lane. Is this function linear?

A large residential area has 1500 households with an average household income of $15,000, an average household size of 5.2, and, on the average, 1.2 working members. Using the model below, predict the change in the number of peak-hour social/recreational trips if employment in the area increased by 20% and household income by 10%. number of peak-hour vehicle-based social/recreational trips per household = 0.04 + 0.018(household size) + 0.009(annual household income [in thousands of dollars]) + 0.16(number of nonworking household members) Round off final answers to whole number.
Two routes connect an origin-destination pair with performance functions t₁ = 5 + (x₁/2)² and t₂ = 7+ (x2/4)² (with t's in minutes and x's in thousands of vehicles per hour). It is known that at user equilibrium, 75% of the origin-destination demand takes route 1. What percentage would take route 1 if a system-optimal solution were achieved, and how much travel time would be saved?
Note: Read the question carefully and give me BOTH right solutions with clear calculations. Vehicles begin to arrive at a toll booth at 5 vehicles per minute from 7 AM to 8 AM. The booth opens at 7:15 AM and services at a rate of 3 vehicles per minute until 7:45 AM. From 7:45 AM until 8 AM the service rate is 6 vehicles per minute. Assuming D/D/1 queuing, (A) have all vehicles that arrived between 7AM and 8AM exited the queue? and (B) what is the total vehicle delay while the queue exists?
