Study Notes
National Highways
- Connect major ports, foreign highways, and capitals of states/union territories
- Also connect large industrial and tourist centers
- Classified as main highways running through the country
Bituminous Roads
- Appropriate for driving conditions
- Subgrade soil conditions determine the thickness
Gravel Roads
- Preferable to earthen roads
- Pavement material is a compact blend of gravel and earth
Static Vehicular Characteristics
- Include vehicle dimensions, weight, axle configuration, turning radius, and turning path
Traffic Engineering
- Covers a broad range of engineering applications, focusing on public safety, efficient use of transportation resources, and mobility of people and goods
Highway Planning
- Engineering discipline that involves planning, design, construction, operation, and maintenance of roads, bridges, and tunnels
- Aims to ensure safe and effective transportation of people and goods
Expressway
- Divided major roadway with full control of access, no crossings at grade
- Designed for higher capacity and uninterrupted flow
Perception-Reaction Time (PIEV Time)
- Broken down into four components: perception, intellection, emotion, and volition
Road Transportation
- Movement of goods and people using vehicles on road networks
- Most flexible mode of transportation
Railway Transportation
- Conveyance of passengers and goods using trains on a track or rail system
Maritime Transportation
- Transporting goods and passengers via sea or inland waterways using ships, boats, and other vessels
Air Transportation
- Movement of people and goods by aircraft, including airplanes and helicopters
Pipeline Transportation
- Transportation of liquids, gases, or slurries through pipelines
Intermodal Transportation
- Transportation process that involves the use of two or more modes of transport (e.g., rail, road, sea, and air) to move goods from origin to destination
Permanent Road User Characteristics of Road Transportation
- Flexibility and Accessibility
- Cost Effectiveness
- Speed and Convenience
- Safety and Security
- Versatility
Railway Topographic Surveys
- Guard Rails: Longitudinal barriers placed on the outside of sharp curves and at sections with high hills
- Function: Restrain and redirect errant vehicles and prevent them from leaving the roadway
- Curbs: Raised structures made of either Portland cement concrete or bituminous concrete (rolled asphalt curbs)
- Function: Delineate pavement edges and pedestrian walkways
Origin and Destination Studies
- Determine the number of vehicles, their origins, and destinations
