Study Notes
Transportation Planning Process
- Essential for analyzing proposed transportation alternatives and their benefits to travelers and communities.
- Highway and traffic engineers forecast travel demand, evaluate economic and non-economic factors, and identify solutions for short, medium, and long-range needs.
Elements of Transportation Planning
Situation Definition
- Initial phase focused on understanding the context leading to the need for transportation improvement.
- Basic factors contributing to current transportation conditions are described.
- Information is gathered regarding the area, demographics, and travel habits.
Problem Definition
- Objective of defining the transportation problem related to project goals.
- Goals include reducing traffic congestion, improving safety, maximizing user benefits, and reducing noise.
- Objectives are translated into quantifiable criteria.
Search for Solutions
- Exploration of diverse ideas, designs, and configurations to address the identified problem.
- This brainstorming stage generates multiple options for further evaluation.
Analysis of Performance
- Assessment of how proposed alternatives perform in present and future scenarios.
- Performance criteria established in earlier phases are applied to each transportation option.
- Investment costs for construction, maintenance, and operation are estimated.
Evaluation of Alternatives
- Focus on how well each alternative meets project objectives based on previously defined criteria.
- Benefits and costs associated with each option are computed using performance data.
Choice of Project
- Project selection considers all relevant factors impacting the decision.
- In simple cases, criteria such as cost may determine the chosen project.
- Ethical practices demand comprehensive evaluation of alternatives and provision of relevant information for informed choices.
Specification and Construction
- Following project selection, a detailed design phase begins, specifying components of the transportation facility.
- This includes physical location, geometric dimensions, and structural design.
- Design plans are created for contractors to estimate project costs, guiding the construction process when a firm is selected.
