a. Determine the share (proportion) ofperson-trips by each of two modes(private auto and mass transit) using themultinomial logit model and given the following information:Utility function: Uk = Ak - 0.05 Ta - 0.04 Tw - 0.03 Tr - 0.014 CParameter Private Auto BusTa = access time (min.) 5 10Tw = waiting time (min.) 0 15Tr = riding time (min.) 25 40C = out-of-pocket cost (cents) 150 100Calibration constant, Ak 0.01 0.07 b. After implementing service improvements to the buses, the mode splitchanged to 60.6% private auto use and 39.4% bus use. Determine avalue for the calibration constant for the bus mode that reflects this shiftin mode split.

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.

Q3: - The new Ring Road that will be constructed in Basrah Governorate is expected to serve AADT of 75000 veh/day. Assuming that a 60/40 directional split (60% in the peak direction), a design hour factor (K) is 12% and the traffic composition includes 75% passenger cars and 25% trucks. Assume truck = 2 pcu, normal growth rate 30% for all design period, generated growth 20%, development growth 250% and Ideal capacity 1000 cu/hr/lane. Determine number of lanes needed for 0-60% the design of this roadway.

5. Find the level of service of the following road: (45 points) ▪ ▪ 6-lane multilane highway, terrain: 2 miles long 4% upgrade, speed limit: 55 mi/h lanes: 11ft, a two-way left-tum lane in the median, right shoulder: 5 ft, PHF: 0.90 peak hour traffic volume in each direction: 4500 veh/h with 10% SUTs and 5% TTs ▪ 30 access points in 2 miles ▪ Solution ET = 2.745 fHV = 0.792 Vp 2104 pc/h/In FFS = 50.15 mph c = 2083 pc/h/In S = 46.13 mph D = 45.61 pc/mi/In LOS F

ramps within 3 miles upstream and downstream of the segment midpoint. It is on rolling terrain with 10% heavy vehicles and is operating at capacity with a peak-hour factor of 0.9. If the road is expanded to four 11-foot lanes with a 2-foot right shoulder, and traffic after the expansion is projected to increase by 10% with the same heavy vehicle percentage and peak-hour factor, what is the new LOS and estimated density? P-22 Chapter 6 Problems hour. What would be the LOS before and after the heavy vehicles are allowed on the upgrade (assuming 50% SUTs and 50% TTs.)? 6.21 A multilane highway has four lanes (two lanes in each direction) and a measured FFS of 55 mi/h. The directional peak-hour volume is 1900 vehicles (the peak-hour factor is 0.80). One upgrade is 5% and is 0.62 mi long. Currently, heavy vehicles are not permitted on the highway, but local authorities are considering allowing heavy vehicles on this upgrade. If this is done, they estimate that 150 heavy vehicles will use…

Given the following transportation network with travel time in minutes: 3 2 2. 3 4 3 The trip production from TAZ 3 is 1,000. The trip attractions from TAZ 3 to all other zones are shown below: From/To 1 500 2 300 4 Trip Attraction 300 The minimum path from zone 3 to zone 1 is: Links 3-4, 4-1 5 min Links 3-2, 2-1 Link 3-1

Consider the freeway and traffic conditions described in Problem 6.3. If 180 of the 1800 vehicles observed in the peak hour were large trucks and buses, what would the level of service of this freeway be on a 5-mi, 6% downgrade?

4. Given the utility expression UK = where Ta is the access time, Tw is the waiting time, Tr is the riding time, and C is the out-of-pocket cost.
