Gaps and Barriers : Design List
General Guidance | Design List | Evaluation Summary
1. 1 Vehicle Barrier : Bollards
Bollards provide one of the simplest means of controlling access by vehicles and can be fabricated from timber, steel, plastic or stone. The distance between the bollards will determine the types of user that will be able to pass. Details are provided of basic designs of timber and steel bollards that can be manufactured locally, including fixed and removable versions. Specialist manufacturers and suppliers of bollards are also listed.
A 1500mm long, timber vehicle barrier that can also be used as seat. The distance between adjacent barriers will determine the types of user that will be able to pass. This design is best suited to rural locations where there is limited vehicle pressure or risk of vandalism and damage.
A 2000 mm long, timber vehicle barrier, similar to 1. 2 , but which is not suitable for use as a seat. The distance between adjacent barriers will determine the types of user that will be able to pass. This design is best suited to rural locations where there is limited vehicle pressure or risk of vandalism and damage.
A simple design of timber edging re-using old telegraph poles to define the limit of permitted vehicle access. It is especially suited to use as an edging to informal rural car parks. Its limited height means that it is not effective against more determined drivers, and especially those in four wheel drive vehicles.
A lockable, steel swing barrier suitable for controlling vehicle access along private roads and tracks. The provision of a gap or gate alongside will permit access by other users. The length of the barrier can be manufactured to suit, up to a maximum of 4000mm. It is strong, resistant to damage and vandalism and also reasonably easy to repair.
Two designs of cycle chicane. The York Chicane and Fife Chicane allow cyclists to pass through without dismounting, whilst preventing access by motorcyclists. Both are normally fabricated from tubular steel, although the former can also be made from timber or stone. Provision for access by other users should be accommodated through the installation of a gate alongside.
1. 7 Horse Stile/Motorcycle Barrier (Version 1)
A basic design of two bar horse stile fabricated from re-used railway sleepers. Such a stile should only be installed where there is a proven and demonstrable need to deter access by motorcyclists along a path used by horseriders. Provision for access by other users should be accommodated through the installation of a gate alongside.
1. 8 Horse Stile/Motorcycle Barrier (Version 2)
A two bar horse stile, similar in design to 1. 7 , but fabricated largely from steel, making it more robust and less susceptible to damage and vandalism.
1. 9 Horse Stile/Motorcycle Barrier (Versions 3 & 4)
Two designs of horse stile that use a single, rather than a double bar. They are therefore simpler to construct and easier for horseriders to use, but are also less of a deterrent to motorcyclists. Version 3 (a design from the Formartine & Buchan Way) is fabricated from steel tubing whilst Version 4 (a design from the Speyside Way ) is fabricated from timber.
1. 10 The Three Valleys Barrier
A patented design of galvanised steel barrier suitable for use on some paths. It permits access by pedestrians, single pushchairs, cyclists, and users of manual and small motorised wheelchairs but prevents access by motorcyclists. It is also inaccessible to double childrens' pushchairs, horseriders and types of larger motorised wheelchair with a hood. It has no moving parts and is robust and resistant to vandalism.
