Sign design Sign dimensions Design teams should refer to the Traffic Signs Manual and TSRGD to select the current size of regulatory or warning sign appropriate for the traffic speed. Refer to Appendix A of the Local Transport Note 1/94: Design and Use of Directional Informatory Signs for further information on directional sign heights and siting distances. Fonts The smallest text size appropriate for the traffic speed should be used, to keep overall sign sizes to a minimum. Figure 251: Signage content should be clear and legible for users Content Design teams should consider how signage can be simplified to include only essential information and optimise legibility, subject to any strategic or local signing requirements. Finish The finish of sign posts and the sign reverse should coordinate with lighting columns and similar street furniture within a given locality. The use of grey or yellow ‘backing boards’ behind signs should be avoided unless considered absolutely vital to road safety. Legislation, statutory powers and consents On the TLRN, only TfL has the statutory power to permit traffic signs to be erected or removed. Figure 252: TLRN traffic restriction Illumination Signs should not generally be illuminated unless legally required to, as specified in TSRGD.

Expert advice should always be sought from a specialist to ensure compliance. Statutory requirements and detailed guidance on the design of signing for the public highway are provided in the TSRGD. For sign legends not covered in TSRGD, separate special sign authorisation is required from the DfT. The proposals put forward in the DfT’s policy paper, Signing the Way, give greater local flexibility and discretion in the design of non-standard signing and provide a framework for the removal of traffic signals. Further guidance is given in the TSM and the Local Transport Note (LTN) 1/94. Signs requiring legal backing by road traffic orders can take up to three months to process and adequate time must be allowed in programmes to accommodate this. Additional information Legislation: Traffic Signs Regulations and General Directions (TSRGD) Department for Transport: Traffic Advisory Leaflet 01/13 (2013): Reducing Sign Clutter Signing the Way 2011: Traffic Signs Policy Paper Traffic Signs Manual 1982 and 2013 Local Transport Note 1/94: Design and Use of Directional Informatory Signs 12.2. Bollards and low level traffic signs Bollards tend to be overused or inappropriately located which can create clutter and pose a hazard for those with visual impairments. Bollards are used to discourage vehicles from encroaching on to pedestrian or cycle space, preventing vehicles from running over hidden basements, preventing damage to footway surfaces, street furniture and buildings while reducing the risk of pedestrian injury. Bollards should be treated as a last resort solution and should only be used when all other alternatives have been exhausted. Other necessary street furniture or equipment should be reviewed to identify if it could be used instead to perform the same role as a bollard. Enhanced enforcement may also be a preferable solution to bollards to deter vehicles from encroaching on the footway. Please consult the local authority conservation team when considering the removal or reuse of historic bollards. Figure 253: Bollards protecting footway space Alternatives Design teams should consider where appropriate: • Using street furniture or equipment to create a barrier using cycle racks, tree planting, seating, etc • Using containment kerbs or high edge kerb upstands (140mm or more) • Local strengthening of the footway where vehicles are known to mount the kerb
