Thank youuu please provide a detailed solution.

hello can i get some help please?

Given the following data: The route will use 40-seat standard buses The door opening and closing time is 4 seconds The boarding time is 3.5 seconds and 4.0 seconds for standing passengers The alighting time is 2 seconds Use the attached table to calculate the average dwell time of the bus at each of the 10 stations

A separate trip generation analysis has predicted 800 peak-hour trips for grocery shopping in this area. Given two possible stores, distribute these trips among stores and auto or bus mode.

5-Vehicles start arriving for a booth in a parking lot to receive free brochures at 8:45 A.M at a uniform deterministic rate of 4 per minute and continue to arrive at this rate until 9:15 A.M. From 9:15 to 10:00 A.M. the arrival rate becomes 8 per minute. The brochures are distributed at a uniform deterministic rate of 11 cars per minute over the 45-minute time period only (from 9:15 A.M. until 10:00 A.M). Determine total delay, maximum queue length, and longest vehicle delay.

Answer questions 13, 14, 15 and 16 using the following paragraph: Vehicles arrive at the carpark of an airport. Vehicles have to queue at the single entrance gate of the carpark at 9:00 AM. The arrival rate is constant at 240 veh/hr. However, between 9:00 and 9:40 AM, the parking ticket machine at the entrance works slowly due to a malfunction, and consequently, each vehicle spends 30 seconds to take the parking ticket. After 9:40 AM, the problem is solved and vehicles spend only 10 seconds at the gate to take the ticket. What is the longest vehicle queue? Select one: a.70 b.64 c.80 d.20 OO

It was estimated that the number of trips between north Davis and the campus during the 8-9 AM peak hour is given by the following trip generation model: Q = 500 + 5.0(class) + 0.05(students) where Q is the total number of trips during the peak hour, class is the number of classes taught between 8-9 AM, and students is the number of students on campus. It was further estimated that there are 80 classes taught on campus between 8-9 AM and the student population is 15,000. Furthermore, these trips were accomplished by three modes: auto, Unitrans, and bicycles, whose shares are determined by the following multinomial logit choice model: Um = βm − 0.50C − 0.02T where C is out-of-pocket cost (dollars) and T is travel time (minutes). Values of βm are: Auto : 4.50 U nitrans : 3.0 Bicycle : 2.50 Suppose that the cost of an auto trip, which takes 8 minutes, is $5.50 (includes parking); Unitrans, which takes 25 minutes, costs $1.00; bicycle trips take 12 minutes and cost $0.50 per trip.
