DIRECTIONAL INFORMATORY SIGNS — MISCELLANEOUS mounting where sufficient width is required between the posts to allow the passage of pedestrians with wheelchairs or prams. As the ahead destination determines the width of the sign, by placing this on two lines (sign 1D), the sign width can be reduced slightly where verge or footway width is limited. This modification of the design is at the expense of a taller and larger sign. Finally, sign 1E demonstrates a poor design. This is the largest sign in the group and the arrangement of route numbers does nothing to improve the appearance of the sign.

Figure 11-8 is a map type sign showing the same junction as figure 11-7, except that the A11 has primary route status in this example. The sign therefore demonstrates the use of coloured panels. Sign 2A shows the conventional layout. The "Dorfield" panel has the route number ranged right to allow the route arm to tuck into the destination block. The vertical separation of the two side destinations ("Axtley" and "Dorfield") helps to emphasize the junction layout. Sign 2B has about the same area as sign 2A. The panel positions in sign 2B emphasize the crossroads even further. There is no doubt that "Axtley" is to the left and "Dorfield" to the right. With this arrangement it is not possible to tuck the right turn route arm into the "Dorfield" panel and therefore the route number is ranged left. If the height of the sign were increased, the right turn in sign 2B could be designed as for sign 2A. This would reduce the width of the sign, but the left and right destination panels would be out of balance ("Dorfield" being closer to the vertical route arm than "Axtley"). Sign 2C reduces the sign area to a minimum. However, the short approach arm and the position of the side destination panels do not adequately illustrate the junction layout. Although a space saver, this sign design is not recommended. Sign 2D is similar to sign 2A except that the right turn destination panel is positioned below the route arm. Because the route arm is angled upwards, it tends to dissociate itself from the destination panel. However, the design does work, and because the right turn panel is higher than the left turn panel the nature of 106
