Study Notes
Highways and Road Terminology
- Arterial Highway: Designed for continuous traffic flow, often on a long, uninterrupted route.
- Berm: A horizontal strip built into an embankment or cut, used to break up long slopes and prevent erosion.
- Culvert: A pipe or box structure positioned below road level to carry stormwater runoff.
- Ditch: An artificial channel dug through earth or rock, used for carrying water.
- Divided Highway: A highway with separated roadways for traffic moving in opposite directions.
- Expressway: A divided highway designed for through traffic, with controlled access and grade separation at intersections.
- Manhole: A removable cover that allows access to sewer conduits and other closed structures for inspection and maintenance.
- Median: The portion of a divided highway separating the roadways for traffic traveling in opposite directions.
- Parkway: A portion of a highway including shoulders for vehicular use, often landscaped and scenic.
- Shoulder: The portion of the roadway adjacent to the traveled way, used for stopped vehicles, emergency access, and providing lateral support to the road base and surface.
- Subgrade: The prepared foundation layer of the roadbed, upon which the subbase and surface courses are constructed.
- Traveled Way: The portion of the roadway intended for vehicle movement, excluding auxiliary lanes, shoulders, bike lanes, parking lanes, and gutters.
- Weep Hole: An opening built into retaining walls, aprons, linings, and foundations to drain water that collects behind and beneath these structures, reducing hydrostatic pressure.
- Topography: The arrangement of the natural and artificial physical features of an area, influencing road design.
- Design Volume: The estimated number of vehicles expected to pass a point on a roadway over its lifespan.
- Design Speed: The maximum safe speed that vehicles can maintain over a specific section of highway under optimal conditions, based on the highway's design features.
- Roadway Capacity: The maximum hourly rate at which vehicles can be expected to travel through a specific point or section of a lane or roadway under given traffic and control conditions.
- Clear Zone: An area along the side of the traveled way, including the shoulder, that provides space for an errant vehicle to recover safely.
- National Roads: Classified as primary and secondary, denoting their importance and role in the national transportation network.
Highway Terminology
- Arterial Highway: A major road designed for continuous through traffic.
- Berm: A horizontal strip built into an embankment or cut to stabilize slopes and prevent erosion.
- Culvert: A pipe or box structure under a road that carries stormwater runoff.
- Ditch: An artificial channel for carrying water, constructed in earth or rock.
- Divided Highway: A road with separate lanes for traffic moving in opposite directions.
- Expressway: A type of divided highway, designed for high-speed, uninterrupted travel with controlled access and grade separations.
- Manhole: An access point for inspection and maintenance of underground utilities like sewer lines.
- Median: The central separation on a divided highway, separating opposing traffic lanes.
- Parkway: A type of highway that includes shoulders for vehicle use.
- Shoulder: The strip of roadway adjacent to the traveled way, used for emergencies and lateral support.
- Subgrade: The prepared foundation layer for the roadbed.
- Traveled Way: The portion of the roadway designed for vehicle movement, excluding auxiliary lanes, shoulders, bike lanes, parking lanes, and gutters.
- Weep Hole: A drainage opening in retaining walls, aprons, and foundations to reduce hydrostatic pressure.
- Topography: The arrangement of the natural and artificial physical features of an area.
Highway Design and Operation
- Design Volume: The estimated number of vehicles expected to use a highway section over its lifespan.
- Design Speed: The maximum safe speed vehicles can maintain on a given section of highway when conditions are ideal.
- Roadway Capacity: The maximum hourly number of vehicles that can pass a point on a road under specific traffic conditions.
- Clear Zone: The area alongside the traveled way, including the shoulder, that provides room for a vehicle to recover from a potential accident.
- National Roads: Classified as primary or secondary, indicating their importance and role within the national road network.
