(a)
Average unit cost for operating a standard vehicle on a level roadway.
Answer to Problem 7P
Explanation of Solution
Calculation:
The average unit cost for operating a standard vehicle on a level roadway is as follows:
Let the depreciation cost per mile as
Let the registration and insurance cost per mile as
Let the maintenance cost per mile as
Let the fuel cost per mile as
The total cost required per mile by adding all the costs.
Total cost required per mile
Total cost required per mile
Conclusion:
Therefore, the average cost required for operating a standard vehicle on a level roadway is
(b)
Average unit cost for travel time for a truck.
Answer to Problem 7P
Explanation of Solution
Calculation:
The average unit cost for travel time for a truck.
Let the cost required per mile to operate the truck as
For the total unit costs using the relation
Substituting the values, we get
Substitute the value of
Let the average speed be
Substitute
Conclusion:
Therefore, the estimate average unit cost for travel time for a truck is

- (show your solutions) Given the figure above, compute for the Annual Average Daily Traffic of all vehicle types: * A.338 B.None of the above C.393 D.418 E.431arrow_forwardA toll bridge carries 10,000 veh/day. The current toll is ₱150/vehicle. Studies shown that for eachincrease in toll of ₱25, the traffic volume will decrease by 1000 veh/day. It is desired to increasethe toll to a point where revenue will be maximized.a. Write the expression for travel demand on the bridge related to toll increase and currentvolume. b. Determine the toll charge to maximize revenues. c. Determine traffic in veh/day after toll increase. d. Determine the total revenue increase with new toll.arrow_forwardAn existing toll road has an average traffic volume around 6,000 vehicles per day. A project is proposed to widen the toll road to increase the road capacity. It is projected that the traffic volume would increase to 10,000 vehicles if the toll rate is reduced from $5 to $4 per vehicle. Assume that the toll rate is the only factor affecting the traffic volume on the toll road. a) Determine the impact of the toll change on consumer surplus. b) Calculate the point elasticity of demand for the toll road. c) Calculate the arc elasticity of demand for the toll road.arrow_forward
- During morning peak hour, the passenger demand is 600. Assume that passenger demand is evenly distributed within that period and the average load/occupancy is 50 passengers per bus. Calculate the average headway of a city buses? If the passenger demand increases to be 750, calculate the number of bus units need to be added and the headway shorten?arrow_forwardWhat are your three alternatives for reducing the delays caused by traffic? Which of these two options is superior, and why?arrow_forwardThe demand and supply function for a bridge are the following where C is cost in cents and V is volume in veh / h . Demand V = 1500 - 10C Supply or cost function: C = 120 + 0.5V (a) What is the equilibrium volume of traffic and the associated cost? (b) 20 cents of toll is added to the cost function, what will be the new cost function and the equilibrium volume?arrow_forward
- A student records the number of vehicles that pass through a toll road lane, as shown in the following list Calculate: (b) what is the busiest current rate for each 5 minute period?arrow_forwardDescribe the principles of transportation system performance measurement and evaluation.arrow_forwardA certain single lane/on-ramp highway was estimated to have a utilization ratio of 0.893. The rate of arrival of vehicles follows a negative exponential distribution with an average of 296 vehicles per hour. If the service rate is also known to be stochastic, a.Compute the service rate in vehicles/hr. b.Compute the average waiting time at the stop sign per vehicle in seconds. c.Compute the average time spent in the system in seconds.arrow_forward
