ABSTRACT
Regulatory traffic management has its basis in law, and uses mandatory and prohibitory traffic signs and markings (see Chapter 28) to inform drivers regarding what they must and must not do in relation to speed, movement and waiting. Regulatory measures of particular interest include speed limits, restrictions on turning movements, the closure or one-way operation of streets, tidal-flow operation of major roads, priority for high-occupancy vehicles, and on-street waiting restrictions and parking control.
