SIGNING PRINCIPLES

615
615.1
811
811.1


D4.7.2 "Priority" signs to diagrams 615 and 811 to indicate which direction of traffic flow has priority at places where the more rigid

control imposed by the above means is not justified because, although the works may be of some duration, traffic is very light (for example, less than about 800 vehicles per hour). Explanatory plates to diagrams 615.1 and 811.1 must be used in combination with signs 615 and 811 respectively. See also Section D5.7.

3000.1

D4.7.3 Portable light signals – temporary traffic signals normally mounted on tripods which are intended for positive control of traffic on shuttle lanes for relatively short periods of time. Positive traffic control using temporary traffic signals is dealt with in Section D5.10.
