With regard to the Test Plan, the distinction can be made between the Master Test Plan and the Level Test Plan (IEEE 829 â 2008). The Master Test Plan covers all test levels for a project. For each Test Level for which it is relevant, a Level Test Plan can be made.
A turn in represents a turn from the major road into the minor road. A turn out represents a turn out of the minor road onto the major road. A 3-way junction allowing all four of these turns is characterized as full-movement. These terms also apply to turns between roads and driveways.
Auxiliary lanes at intersections and interchanges often help to facilitate traffic movements. Such added lanes are to be as wide as the through-traffic lanes but not less than 10 ft. Where continuous two-way left-turn lanes are provided, a lane width of 10 to 16 ft. provides optimum design. Category: 231 Typical Section Elements for Roadways.
