NOTES:

(1) Detail 6.12.1 shows standard “11d” increments for Type 3 arrows.

(2) Detail 6.12.2 similarly gives the size range for Type 5 arrows (for dimensional details of all arrows see Section 6.5).

(3) The radius of curved straight-on arrows may be varied but should be the same for all arrows in a cluster (cluster 4 – Detail 6.12.3).

(4) Inclined arrows should tend towards 30o for more acute exit curves (Details 6.12.4 and 6.12.5).

INTRODUCTION 6.1.17


NOTES:

(1) Arrows and clusters are arranged in order of increasing height vertically, and increasing width laterally in the figure.

(2) Clusters marked thus ● are for use on at-grade roadways

only.

INTRODUCTION 6.1.18


NOTES:

(1) Details 6.14.1 and 6.14.2 illustrate the colour coding of the sign background and the INSERT PANEL. (See Chapter 1 for the key to colour hatching.) The colour treatment is independent of the message contained in the INSERT PANEL.

(2) Detail 6.14.3 gives dimensional details appropriate to this type of INSERT PANEL.

(3) The INSERT PANEL may include a route number or a route number plus Toll Route symbol GDS-9 or Alternative Route symbol GDS-10.

(4) When symbols GDS-9 or GDS-10 are used the side space between the MAP-TYPE arrow and the border should be increased from “9d” to “13d” or more to maintain a minimum “2d” clearance between border and INSERT PANEL.

number. The normal treatment is to allow the bracket to intrude into an

OUTER space. However, if the bracket is adjacent to an arrow the

lateral space should be increased so that ir refers to the space between

the edges of the arrow and the bracket. The line of justification shall be

maintained but moved to the right.
