Secondary roadway: the lower functionally classified road at an intersection.
Setback: a distance from a curb, property line or structure, within which building is prohibited.
Sight distance: the distance along the road visible to the driver. It is measured along the normal travelled path of a roadway from the driver's location to a specified height above the roadway when the view is unobstructed by traffic. Required sight distances for entering a right-of-way can be affected not only by the curve of the road, but also the grade, and the travelled speed of traffic using the road. Ideally, the driver should be able to count to six before a car travelling the length of the sight distance arrives at his or her location. For trucks, the driver should be able to see the truck, then count to 10 to make a safe entry.
Sight Triangle: the area formed by a triangle in the angle formed by the right-of-way boundaries and two points on those boundaries 6 m from the point of intersection, as shown crosshatched in the diagram following:
Signal: a traffic control signal.
Site Impact Analysis: a technical review undertaken to determine the effect or impact of a proposed development on the surrounding highway system.
Stopping sight distance: the distance required by a driver of a vehicle, travelling at a given speed, to bring the vehicle to a stop after an object on the roadway becomes visible. It includes the distance traveled during driver perception and reaction times and the vehicle braking distance.
Subdivision: a legal mechanism used to create new parcels of land. It may include the consolidation of land or the division of land into two or more parcels.
