I would appreciate it if you could provide more details and explain its function.arrow_forwardDevelop a detailed analytical framework using life-cycle cost analysis of a freeway system operation improvement project, such as a project for varying freeway speed limits in the range of 45- 70 mph for different locations and time periods of a typical working day.arrow_forward12) List and define the 4 steps of the "4-step travel demand model" used in transportation planning.arrow_forward
- 1. Transportation planning may be viewed as both a rational intellectual process and as a political process. Briefly describe the main features of these two perspectives. 2. Select transportation planning study for which a report is available. In five pages or less, summarize the goals, methods, findings and recommendations of the study. 3. What sorts of information are typically contained in a proposal for a transportation planning study?arrow_forwardThree designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area. The first alternative involves improved traffic signaling. The second alternative includes traffic-signal improvements and intersection widening for exclusive left turns. The third alternative includes extensive reconstruction, including a grade separation structure. The construction costs, as well as annual maintenance and user costs, are listed in the following table for each alternative. Determine which alternative is preferred based on economic criteria if the analysis period is 20 years and the annual interest rate is 15%. Show that the result is the same using the present worth, equivalent annual cost, benefit–cost ratio, and rate-of-return methods.arrow_forwardThree designs have been proposed to improve traffic flow at a major intersection in a heavily traveled suburban area.

- The Department of Traffic is considering three improvement plans for a heavily traveled intersection within the city. The intersection improvement is expected to achieve three goals: improve travel speeds, increase safety, and reduce operating expenses for motorists. The annual dollar value of savings compared with existing conditions for each criterion as well as additional construction and maintenancecosts is shown in the table below. If the economic life of the road is considered to be 60 years and the discount rate is 3.5%, which alternative should be selected? Solve the problem using the four methods for economic analysis.arrow_forwardSubject: ( Transportation planning and engineering )arrow_forwardThe Department of Traffic is considering three improvement plans for a heavily traveled road within the city. The road improvement is expected to achieve three goals: improve travel speeds, increase safety, and reduce operating expenses for motorists. The annual dollar value of savings compared with existing conditions for each criterion and additional construction and maintenance costs is shown in Table 1. If the economic life of the road is considered to be 53 years and the discount rate is 4%, which alternative should be selected? Evaluate the two proposals based on economic evaluation criteria using the Net Present Worth (NPW) and benefit-cost ratio (BCR) methods for economic analysis.arrow_forward
- Discuss the advantages and disadvantages of increasing transportation safety and secu- rity regulations. Be sure to include both transportation providers and transportation users in your discussion.arrow_forward1. Assume that the following goals have been established for a transportation planning study.Goal 1: The transportation system should provide mobility for all segments of the population.Goal 2: The transportation system should minimize the impact on the natural environment.Define at least three objectives for each goal that could be used to achieve the stated purpose. 2. From the sketch below, calculate the interzonal trips due to 450 work trips produced at zone i. There are 750 attractions at zone 1, 400 attractions at zone 2, and 300 attractions at zone 3. The exponent of travel time is 0.6 and the travel times are 9 minutes to zone 1, 5 minutes to zone 2, and 7 minutes to zone 3. Assume all socioeconomic adjustment factors and the value of C are equal to 1.0.arrow_forwardCost-Effectiveness Analysis Exercise The transport planners of City Y wish to introduce a major new public transport system to the city center district. The transportation planners are provided with 3 alternatives: Rapid Bus Transit (RBT), Light Rail transit (LRT), and Express Train Transit (ET), and there is an existing baseline transport system. The expected lifetime is 34 years and the MARR is 9%. Find the best alternative using the cost-effectiveness analysis.
