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 = Bm 0.50C 0.02T where C is out-of-pocket cost (dollars) and T is travel time (minutes). Values of ẞm are: Auto: 4.50 Unitrans: 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.

Question - Based on observations of condos with 100 units, it is be lieved that the mean number of parking spaces desired is 70, with a standard deviation of 4.6. If we are to build a larger complex with 1,000 units, what can be said about he parking?
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.
QUESTION 3 a) Road accident 'black spots' are locations that attract more accidents by comparison with other similar locations on the road system. Speed has been identified as a key risk factor in road traffic injuries at 'black spots' influencing both the risk of a road crash as well as the severity of the injuries from the crash. Interpret FIVE (5) benefits resulting from a spot speed study at the 'black spots' location conducted during Malaysia's festival season at KM399.8 of North-South Expressway. (CO1-PO3)(C3)

A toll bridge carries 6000 vch/day The current toll is $3.50/vehicle. Studies have shown hat for each increase in toll of 50 cents, the traffic volume will decrease by 500 veh/day. Jus desired to increase the toll to a point where revenue will be maximized. (a) Write the expression for travel demand on the bridge, related to toll increase and current volume. (b) Determine the toll charge to maximize revenbes. (o Determine traffic in vel/day after the loll increase, (d) Determine the total revente increase with the new tol.
Determine the severity number for a section of highway that had 2 fatal crash, 48 personal injury crashes, and 105 property damage only crashes during a particular time period. Use a weighting scheme of 50 for fatal crashes, 25 for personal injury crashes, and 1 for crashes with only property damage. Determine the severity index by dividing the severity number by the total number of crashes, thereby normalizing the severity number by the number of crashes.
