There are several different types of cylinders and bollards which can be used within traffic management and segregation schemes. For example, a standard conical traffic bollard, which has a flat square base, can be used. This bollard will be easily recognised most as a commonly used traffic bollard. It is not fixed to the road and can be picked up and moved very easily. Alternatively, ‘knock down’ cylinders, are traffic bollards which can be knocked down but are fixed, in some way, to the road. They can delineate traffic flow but also provide an ability to emergency services to negotiate a traffic management system. Other cylinders exist which are also designed to be knocked down, but then immediately swing back into place (thereby granting blue light access). These cylinders are referred to as ‘swing back cylinders’, one particular design being the “Swinbac cylinder”. Different examples of cylinders and other traffic management tools or equipment were in the bundle at 722 and onwards.

‘Pin-in’ cylinders are another different type of cylinder. Kingpin cylinders are a particular make of pin-in cylinder. They are not designed to be knocked down. They consist of a base and a separate, detachable ‘bollard’ or ‘wand’. The base must be fixed to the road surface, either through adhesive glue type substance or by being bolted to the road. The wand can be removed from the base, thereby enabling emergency vehicles to pass through.

Further evidence regarding how Kingpin cylinders can be installed and removed is set out below.
