whats the difference between contraflow and with flow
Contraflow lane In transport engineering nomenclature, a counterflow lane or contraflow lane is a lane in which traffic flows in the opposite direction of the surrounding lanes.
Flowchart The first structured method for documenting process flow, the "flow process chart", was introduced by Frank and Lillian Gilbreth to members of the American Society of Mechanical Engineers (ASME) in 1921 in the presentation "Process Charts: First Steps in Finding the One Best Way to do Work".[2] The Gilbreths' tools quickly found their way into industrial engineering curricula. In the early 1930s, an industrial engineer, Allan H. Mogensen began training business people in the use of some of the tools of industrial engineering at his Work Simplification Conferences in Lake Placid, New York.
