2. What is Transportation?
• Movement of goods and people from one place to another
• Safe, efficient, reliable, and sustainable movement over time and space

3. What is Transportation Engineering?
• A branch of civil engineering focused on transportation infrastructure
• Involves planning, design, operation, and management of facilities
• Goal: safe, rapid, comfortable, economical, and eco-friendly movement

4. Characteristics of Transportation Systems
• Multi-modal: air, land, sea
• Multi-sector: government, private, public
• Multi-problem: policy, planning, management
• Multi-objective: economic, environmental, social goals
• Multi-disciplinary: engineering, economics, law, social sciences

5. History of Transportation
• From walking to use of animals, wheel, roads
• Development of roads and transport technologies over time
• Role of transportation in urbanization and civilization growth

6. Major Disciplines of Transportation
Engineering
• Transportation Planning
• Geometric Design
• Pavement Design
• Traffic Engineering
• Public Transport, Economic Analysis, Environmental Assessment
• Accident Analysis, Intelligent Transport Systems

7. Modes of Transportation
• Land: Road, Rail, Pipelines
• Water: Shipping, Inland waterways
• Air: Passenger & cargo transport
• Intermodal: Using multiple modes effectively

8. Transportation System Components
• Fixed facilities: roads, railways, ports, airports
• Flow entities: vehicles, trains, aircraft, ships
• Control systems: traffic lights, ATC, road signs

9. Role of Transportation in Society
• Economic: supports production, distribution, consumption
• Social: connects rural & urban, cultural exchange
• Political: links political units, supports governance
• Environmental: pollution, safety concerns

10. Historical Development of Roads
• Roman Roads: durable, drainage-focused
• Tresaguet Roads: compact stone layers
• Telford Construction: graded stone sizes
• Macadam Roads: interlocked stones
• Modern Roads: asphalt, concrete, advanced tech

11. Transportation Planning
• Short, Medium, Long-term planning
• System approach: analysis, engineering, decision-making
• Consider demand, economic, social, environmental factors

12. Objectives of Road Planning
• Establish integrated road networks
• Fulfill societal needs
• National, urban road network planning
• Patterns: Grid Iron, Radial, Ring Roads

13. Classification of Roads (Nepal)
• Administrative: National Highways, Feeder, District, Urban Roads
• Technical: Based on design speed & traffic volume
