16. A bus line operates in mixed traffic and carries 4000 passengers per peak hour at an average speed of 10 mi/h. Typically each bus makes two scheduled stops per mile and is interrupted by the traffic control system and other vehicles six times per mile. Given an average occupancy of 50 persons per bus and a 5-mi trip, calculate the number of buses needed to serve the passenger demand and the total amount of fuel consumed during a typical peak hour.

In order to facilitate passenger transport, an express bus system is to be set up between AIT Campus and Kwame Nkrumah Interchange at a distance of 13.73 miles. The operating time is expected to be half an hour. The estimated peak demand is 3500 passengers/hr. The available buses have a seating capacity of 35 and space for 25 standees. Given a terminal time of quarter hour, determine the departures per hour and number of buses that will be required to serve the passenger demand.
(A) Two buses start at the same time towards each other from terminals A and B, 8 km apart. The time needed for the first bus to travel from A to B is 8 minutes and of the second bus B to A is 10 minutes. How much time is needed by each bus to meet each other if they traveled at their respective uniform speeds. (B) Each of the two identical shafts is attached to a rigid wall at one end and supported by a bearing at the other end. The gears attached to the shafts are in mesh. Determine the reactive torques at A and C when the torque T is applied to gear B. A T B D R alm R
The arrival rate at a parking lot is 6 veh/ min. Vehicles start arriving at 6:00 P. M., and when the queue reaches 36 vehicles, service begins. If company policy is that total vehicle delay should be equal to 540 veh-min, what is the service rate? (Assume D/ D/ 1 queuing and a constant service rate.)
At 10 am, vehicles arrive at a toll booth facility at the rate of 480vehicles/hour. Initially, the toll booth is closed from 10:00 am until 10:15 am. Then it opens from 10:15with a service rate of 6 seconds per vehicle. Assuming D/D/1 queuing, determine:(1) At what time queue disappears? (2) What is the total delay? (3) What is the maximum Queuelength? (4) What is the queue length at 10:00 am? (5) What is maximum delay? (6) What is thedelay for the 140th and 170th vehicle?
For 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…
The average queue length at the intersection of the two roads with a stop sign is 4 vehicles. If the arrival rate of vehicles at the stop sign is 300 veh/hr, determine the service rate of the road in veh/hr. Assume both arrival and departure rates are exponentially distributed.

The following table shows traffic flow data collected at the main road in an urban area, in two successive days during the peak period Day one Flow (veh) Day two Time Flow (veh) 7:30 – 7:45 7:45 – 8:00 900 950 960 8:00 – 8:15 1010 1015 8:15 – 8:30 990 980 (a) Determine the peak hour factor (PHF) (b) Estimate the missing traffic flow count (x) on day two.
A toll booth on a temple is open from 8:00 AM to 12 midnight. Vehicles start arriving at 7:45 AM at a uniform deterministic rate of six per minute until 8:15 AM and from then on at two per minute. If vehicles are processed at a uniform deterministic rate of six per minute, determine the (a) time of queue dissipation in minutes (b) total number of vehicles in queue and (c) total vehicle delay
1. A total of 5,000 person-trips are made between a commercial district and a residential area during the PM peak hour. Commuters have two modes available, including private automobile and a light- rail transit system. The following utility function was calibrated using data from the study area from users of these two modes: U 3D -0. 50T1 — 0. 50T, — 2. 00С Data summarizing the operational characteristics and costs associated with each mode are provided in the following table. Private Light-Rail Parameter Automobile Transit = in-vehicle travel time (min.) 10 T1 T2 = excess time (min.) C = out-of-pocket cost (dollars) 15 5 10 5.00 2.00 Determine how many trips will be made by each travel mode based on these characteristics.

If uniform deterministic processing of vehicles (collecting fees) begins 30 minutes after the first arrival and the total delay is 3600 veh-min, how long after the arrival of the first vehicle will it take the queue to dissipate?

Find the average running and overall travel speeds. C) A parking garage located in Misan city center opens its doors to serve 350 vehicles from 8 am to 3 pm. An analysis of data collected at the parking site indicates that these vehicles are parked for an average of 1.5 hours. If parking efficiency is 0.9, determine the number of additional spaces needs when the number of space-hours increases by 16%.
