- Q3) A manufacturing plant is to be constructed A manufacturing plant is to be constructed in the city of Ankara, in order to provide a faster service to its major customers in the surrounding area. There are three possible locations the company is considering. The distances (in km) from these three locations to the four major customers are listed in the table below. The transportation cost is approximately 1.00 TL/km. The annualized fixed cost of constructing the plant and the customers' demand (number of trips required per year) are also given in the table. Find the best location for this plant.During morning peak hour, the passenger demand is 600. Assume that passenger demand is evenly distributed within that period and the average load/occupancy is 50 passengers per bus. Calculate the average headway of a city buses? If the passenger demand increases to be 750, calculate the number of bus units need to be added and the headway shorten?Two routes connect a city and suburb. During the peak-hour morning commute, a total of 5000 vehicles travel from the suburb to the city. Route 1 has a 50km/hr speed limit and 5km in length, Route 2 has a 55km/hr speed limit and 4 km in length. Studies show that the total travel time on route 1 increases 2 mins for every extra 500 vehicles added. Mins of travel time on route 2 increase with the square of the no. of vehicles expressed in 000’s. Determine user equilibrium travel times.
- After 10 years, the public transportation remain unimproved. The modal split will also remain unchanged with 70% of person-trips utilize Public Transportation during peak period. After 10 years, the person-trip demand will increase from 450 to 675. If the overall capacity of the Public Transportation during peak period can carry up to 450 person-trips, the demand / PT supply capacity ratio is _______ (answer shall be in 2 demical places) Please correct answerFor this exercise, you are to design a roadway that is to carry 100,000 people a day (excluding truck occupants) – 50,000 in design direction. The vehicles that carry these people include; (1) personal vehicles (average occupancy of 1.2 people per car) 2-2 kip single axles, and (2) buses with 2-22 kip single axles (assume they are filled with an average of 40 passengers). There are also trucks on the roadway and all trucks have 1-40 kip triple axle, 1-32 kip tandem axle, and 1-8 kip single axle. You know that the soil CBR is 6, the initial PSI is 4.5 and the TSI is 2.5. Other values to be used: All drainage coefficients = 1.0 Reliability = 90% Overall standard deviation of traffic = 0.50 Concrete Modulus of Elasticity = 5.5 million lb/in2 Concrete Modulus of Rupture = 750 lb/in2 PCC load transfer coefficient = 3.0 Design a rigid and flexible pavement, to last 15 years, for a four-lane road (four lanes in design direction) with 400 trucks per day in the design direction, and…to no congestion on the road further downstream of the railway grade crossing. QUESTION 5: Consider trip distribution within 5 zones in an area. The total trip production from zone 1 is 1000. The travel times from zone 1 to zones 2, 3, 4 and 5 are 5, 10, 20, and 30 minutes, respectively. The trip attraction to zones 2, 3, 4 and 5 are 50, 200, 75, and 450, respectively. Assume that the number of trips produced from zone 1 to zones 2, 3, 4 and 5 is inversely proportional to the inter-zonal travel time. (a) Estimate the number of trips from zone 1 to zones 2, 3, 4 and 5 using the gravity model. (b) Assume that the future trip production from zone I will increase to 1,250 and the future trip attraction to zones 2, 3, 4 and 5 will increase to 100, 225, 100, and 600, respectively. Predict the number of trips from zone 1 to zones 2, 3, 4 and 5. The inter-zonal travel times remain the same. (c) Compare the number of trips from zone 1 to each destination zone between (a) and (b). Identify the…
- 8.5 If small express buses leave the origin described in Example 8.5 and all are filled to their capacity of 20 travelers, how many work-trip vehicles leave from origin to destination in Example 8.5 during the peak hour?Question: For a two- way bus route, if the demand service is 250 passenger/hr and the route length is 20 km. The route is to be served by 30 seat buses with allow 15 standing passenger with average speed of 40 km/hr. Assuming that all the bus will reach to the destination and leave fully loaded. Also , the bus scheduled must be in 5 minutes increment. Calculate the number of buses required to serve this route ?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)
- Q4c. Which service route types are being operated by the following public transport operators in Ghana; Uber, Intercity-STC Ltd and “floating” trotro? Give reasons.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.8.25 Two routes connect an origin and destination with performance functions t₁ = 5 + 3x₁ and t₂ = 7+ X2, with t's in minutes and x's in thousands of vehicles per hour. Total origin-destination demand is 7000 vehicles in the peak hour. What are user- equilibrium and system-optimal route flows and total travel times?
