Signposting on trunk roads and general roads in the UK

2. Trunk road signage

The trunk road network, which has the largest total mileage in the UK, is an effective complement to the main motorway network and is an important link between motorways and cities, or between cities and towns. Trunk road numbers begin with the letter A. The colours of the signs are green with white text and graphics, and in particular the trunk road numbers are coloured yellow for clarity. The following is an introduction to some common types of wayfinding signs on trunk roads and their use:

(1) Location Distance Forewarning Signs

On trunk roads outside of cities, if the distance between destinations is relatively long, in order to let the driver have a good grasp of the situation, a location distance sign is generally installed to forewarn the name of the location and the distance of the place that can be reached in front of the driver. The first row of the sign layout first displays the number of the road where it is located, and then 2~4 rows display the names and distances of the destinations that can be reached ahead, arranged from top to bottom according to the proximity and distance.

(2) roundabout signs

In addition to motorways, the UK's highways or urban roads are far from domestic wide, generally two to four lanes only, and it is difficult to see high-level interchanges, basically the majority of flat intersections, and the most used, the best for the roundabout. Circular intersection access is to enter the roundabout vehicles must give way to vehicles out of the roundabout, that is, out of the roundabout vehicles have priority, vehicles can only enter the roundabout without affecting the normal driving out of the roundabout vehicles under the premise of the establishment of roundabouts is to allow vehicles in all directions to flow constantly.

(3) Y-shaped and T-shaped intersection wayfinding signs

When driving in the UK, you can see a variety of level crossings, of which Y-shaped and T-shaped intersections are also common forms of level crossings, Y-shaped intersection wayfinding signs, T-shaped intersection wayfinding signs. Their common feature is that the main content of the wayfinding sign is divided into two parts, representing the information of two directions, and labelled with arrows indicating the direction of travel. The wayfinding information is generally a combination of the name of the location and the road number. It must be noted that if the roads are not directly intersected but are articulated, the road number should be bracketed to show the distinction.

(4) deformed intersection signs

Although London, England is a world-famous big city, but its roads are not like Beijing and other domestic cities, spacious roads horizontal and vertical, but often the road is very narrow, and winding, so some irregular deformed intersections in the city in the midst of a number of. For the road instructions of these special intersections, the United Kingdom is based on the actual traffic pattern of the intersection, graphically depicting the arrow pattern of the deformed intersection, although a little complicated, but still clear and easy to understand.

3. General road signs

The general road here mainly refers to some low-grade roads, including urban roads and local roads, in addition to motorways and trunk roads. The colour of general road signs is white background, black text and patterns, when it previews arterial highway information should be used in green with white or yellow characters, when the preview of highway information should be used in blue and white characters. The following highlights several common planar intersection wayfinding signs.

(1) T-intersection wayfinding signs

On urban roads in the United Kingdom, most of the level intersections are set with single-post or double-post signs, one double-post sign and the right-hand post and street lamps to achieve a common pole, a post sign. The body colour of these two T-junction wayfinding signs is black on white, indicating that they are set on the general road. The sign face of the sign is divided into two parts, representing two different directions of interest according to the arrows. The difference is that one sign face is larger and uses an arrow pattern to indicate the direction of traffic, while the other sign face is smaller and is directly made into an arrow shape to indicate the direction of traffic.

(2) Cross junction wayfinding signs

Cross junction wayfinding signs in this country usually use a standard cross arrow to represent 3 different directions of travel, but it is more common in the UK to divide the sign face into three parts, top, middle and bottom, with separate arrows and messages for each direction. Cross intersection wayfinding signs are set up on the general road, but with the intersection of the road for the A11 trunk road, so the left turn and right turn message are green background white or yellow message, through the colour change, increase the driver's attention to the sign, and can help drivers to quickly identify the meaning of the type of sign.

(3) roundabout pointing signs

In London, England, in addition to motorways with overpasses, other roads for the majority of plane intersections, and to the ring; intersections are the most. Roundabout is an important part of the London road network, large roundabout can even be laid in the middle of the square, and there are many intersections, generally need to set up traffic lights for traffic control. Smaller roundabouts generally do not have traffic lights, as long as there is a car into the roundabout, the other several junctions of the car will consciously stop, and then down the line in turn. It is easy to get confused by roundabout traffic and feel that all directions are similar, so it is very important to set up clear and simple wayfinding signs. The point of a directional signage for a small roundabout is that it focuses on graphically depicting the access to the roundabout in a clear and concise manner with important location information so that drivers can recognise it within a short period of time.
