Question 4 Vehicles begin to arrive at a border gate at 06h50 with a deterministic arrival rate of λ (t) = 5.2 - 0.01t (λ is in vehicles per minute and t in minutes after 06h50). However, the gate opens at 07h00 and serves vehicles at a rate of μµ(t) =3.3 + 2.4t (with t in minutes after 07h00 and u in vehicles per minute). Once the service rate reaches 10 vehicles per minute, it stays at that level for the rest of the day. ● ● Illustrate the operational characteristics of the vehicle queue-delay on a (cumulative) vehicle-Time graph. When will the queue that forms be dissipated? What will be the maximum queue length? Determine the total delay.
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.
QUESTION 9 The adjustment for the access point density is based on empirical studies indicating that for each access point per mile, the estimated FFS decreases by 0.25 mi/h, regardless of the type of median. Note that these access points are those that influence traffic flow and that access points that go unnoticed by drivers are not included in the calculation of the access point density. Therefore, what is the expected reduction (mph) in FFS when the access density is 4 access points per mile. (enter a positive value)
Vehicles arrive at a recreational park booth at a uniform deterministic rate of 4 veh/min. 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?

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%.
An expressway consists of four lanes, where the capacity per lane is 2500 vehicles. In normal days, 6500 vehicles pass. However, there is an emergency road repair conducted in which two lanes will be closed. The repair lasted 150 minutes. Calculate the maximum queue length, total length, and number of vehicles impacted by the event, and average individual delay.
HIKI TO D OSHITENOJ ON DE No. Date 3 A parking facility operates from 8 a.m. to 6p.m, whereby 20% of those who wish to park are turned back daily because of lack of space. A total of 200. vehicles are able to park daily of which 60% park for an average parking duration of 9 hours and the remaining park For an average parking duration of 2 hours. From a survey of the vehicles who are not able to park daily it is known that 20% of these vehicles desire to park for 9 hours and the For 2 hours. remaining desire to Park If the parking efficiency is 0.9, determine: Li) the number of additional space hours required? (ii) the additional number of parking bays required in order to meet excess demand?
