11.18 An error commonly seen on both panelled advance direction signs and flag type direction signs is the inefficient layout of multi-part names. Figure 11-13 shows a flag type direction sign indicating a business park, with a three word name. The most economical design for this particular example is to place the destination on two lines, but the difference in area between signs 7A and 7B shows that substantial savings can be made by choosing the appropriate pairing of words. Sign 7A is likely to be used only where it is to be mounted on a backing board with another flag sign of a similar length. Using flag signs of similar length produces a more balanced assembly of signs. Placing the destination on three lines, as shown on sign 7C, increases the height of the sign with only a marginal saving in the overall length. Although the legend block is shorter than that on sign 7B, the chevron takes up more horizontal space because it has increased height and width. The gap between the chevron and the border of the pointing end of the sign is also increased. (See figure 7-1 for chevron sizes.) The most efficient layout in any particular case will of course depend upon the relative lengths of the words involved.
