The type of bollard selected for a scheme should be appropriate for its location and fulfil acceptable physical and visual requirements. Bollard designs should be selected based on the function they need to fulfil: • The design should be appropriate for the character of the area • Telescopic posts may be appropriate for areas which are largely pedestrianised to restrict general vehicle access but allow for servicing vehicles • A number of traditional historic bollards exist on the TLRN, some of which are listed, and should be retained • The method of ground fixing should be detailed to minimise damage to the surrounding footway, should a vehicle collision occur, allowing for easy replacement of the bollard • Bollards should not be linked with chain or rope Options General on footway Removable posts Security bollards Image Application Dimensions Colour Preferred design for urban areas 1,000mm height ±100mm Tapered Round [Part E – Physical design and materials] Safety and functionality 253 RAL coated black Where a street requires temporary vehicular access for servicing or maintenance Minimum 1,000mm height RAL coated black Station and building security Must be specified and fixed in accordance with Publicly Available Specifications (PAS) 68 and 69 Round domed top Silver grey RAL signal grey RAL signal grey Material/finish Cast iron/mild steel Cast iron/mild steel Stainless steel Lighting Unlit with white Unlit with white Unlit with visibility bands visibility bands visibility bands
