The design, installation and any performance assessment of priority measures is a matter for the local highway authority. It is for them to decide what type of priority measures to provide for particular modes of transport.
There is a wide range of engineering and other measures available to local highway authorities to help provide priority to different groups where necessary or desirable. These have been developed over many years and the Department for Transport has published guidance covering good practice in design and installation. These include local transport notes and traffic advisory leaflets, which provide information on the performance of such measures on the ground.
