- 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)arrow_forwardTwo 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?arrow_forwardDuring 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?arrow_forward
- Given that a zone has 200 households with car and 200 households without car and the average trip generation rates for each groups are respectively 4.0 and 2 trips per day. Assuming that in the future, all household will have a car, find the growth factor and future trips from that zone, assuming that the population and income remains constant.arrow_forwardDetermine the trip distribution matrix using "Gravity Model" of transport system with given the data: Trip Production of Zones 1, 2 and 3, correspondingly are 500, 600, and 800 tpd Trip Attraction of Zones 1, 2 and 3, correspondingly are 600, 700 and 600 tpdarrow_forward12) List and define the 4 steps of the "4-step travel demand model" used in transportation planning.arrow_forward
- How to calculate trip generation using household income and car ownershiparrow_forwardAnswer the following questions based on your own understanding. Use your own words for answering: 1. Identify and briefly describe the two basic demand forecasting situations in transportation planning. What are the three factors that affect the demand for urban travel? Define the following terms: (a) home-based work (HBW) trips, (b) home-based other (HBO) trips, (c) non-home-based (NHB) trips, (d) production, (e) attractions, (f) origin, and (g) destination.arrow_forwardAfter 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)arrow_forward
- 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.arrow_forwardA calibration study resulted in the following utility equation for different modes in a particular city;??=??−(0.25)(?1)−(0.032)(?2)−(0.015)(?3)−(0.002)(?4)where ??= mode specific constant?1= access plus egrees time in minutes?2= waiting time in minutes?3= line-haul time in minutes?4= out-of-pocket cost in centsFor a particular origin-destination pair, the forecasted number of trips is 5,000. For this particular trip, there are two modes available, bus and auto.a) If the characteristics of these two modes are as follows, how many trips will be taken by bus? And by car? Assume that the mode specific constant is equal to -0.12 for the automobile and -0.22 for bus.b) Assume that a new mode, rapid transit, is to be introduced into the market between these two zones. The characteristics of this new service are as follows:?1=10 ?2=5 ?3=30 ?4=75 Assume from experience in other cities that the mode specific constant for rapid transit is -0.41. What willbe the modal shares of the 5,000 trips…arrow_forwardAfter 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 answerarrow_forward
