- Launch of Electric Cars: 1998
- Current developments include High-Speed Rail, Driverless Cars, AHS (Automated Highway Systems), and Solar Highway.
Importance of Transportation
- Facilitates communication and information transfer.
- Enhances logistics and trade, preventing regional isolation.
- Enables mobility and relocation of populations.
Modes of Transportation
- Definitions and distinctions among various transport modes.
- Road Transport: Cost-effective for short distances and perishable goods.
- Air Transport: Safe during emergencies, useful for inaccessible areas, supports national security.
- Rail Transport: Efficient for long-distance travel.
Planning Process in Transportation Engineering
- Situation Definition: Assessing the current transportation scenario and needs.
- Problem Definition: Articulating project objectives such as reducing congestion and improving safety.
- Solution Search: Brainstorming various design options and configurations.
- Performance Analysis: Evaluating how proposed solutions will perform, including cost estimations.
- Alternative Evaluation: Analyzing each alternative's benefits against costs.
- Project Choice: Selecting a project after weighing relevant factors, including political judgements and site locations.
- Specification and Construction: Detailing project designs, contractor selection, and transition to operational status.
Urban Transportation Planning
- Involves evaluating and selecting transport facilities for current and future land uses.
- Projects accommodate growing demands from new developments like shopping centers or residential areas.
- Short-term planning: Focuses on immediate improvements within three years (e.g., traffic signal adjustments).
- Long-term planning: Structured for five or more years, encompasses significant infrastructure projects (e.g., new highways).
Establishment of Goals and Objectives
- Identifies deficiencies and outlines improvements for the transportation system.
- Goals often include maximizing ridership, revenue, and development while reducing congestion.
Generation of Alternatives
- Identifies various options for improvement in the urban transportation planning process.
- Involves analyzing the impacts of land-use plans and possible combinations of transportation technologies and policies.
Estimation of Project Cost and Travel Demand
- Determines the cost of projects alongside forecasts of future traffic flows.
- The estimation process is complex and requires advanced modeling.
Four-Step Travel Demand Model
- Key for predicting future traffic volumes based on decision-making in travel.
- Involves: Trip Generation, Trip Distribution, Mode Split, and Trip Assignment.
Trip Generation and Distribution
- Trip Generation: Predicts total trips in each zone; factors include income, car ownership, and land use.
- Trip Distribution: Models trips between origin and destination zones, influenced by production and attraction factors.
Measures of Transportation Demand
- Freight transportation demands vary based on commodity characteristics, urgency, and chosen mode.
