A Passenger Car Unit is a measure used primarily to assess highway capacity, for modelling purposes. Different vehicles are assigned different values, according to the space they take up.
A specific element of road infrastructure, used to allow pedestrians to cross larger roads in multiple phases. Often these have some physcal protection from traffic, and can be combined with pinch points.
A push-button controlled crossing which permits equestrian as well as pedestrian use. A second push-button box is mounted higher up such that the horse rider does not need to dismount to operate the crossing.
PEdestrian LIght CoNtrolled (yes, that is where the name comes from) crossing is an example of a controlled crossing where pedestrians push a button to indicate they wish to cross.

'Presumed liability' (often referred to as 'strict liability') is an element of civil law that, in crashes involving vulnerable road users, finds the more powerful road user liable by default, unless it can be clearly proven that t

The National Propensity to Cycle Tool (PCT) is an online and interactive planning support tool to provide an evidence base to inform investment in cycling.
A term used to describe measures that separate cycling (and indeed walking) from motor traffic. For instance 'protected cycleway' would be a cycleway that is separated from motor traffic by either a physical kerb, or bollards, or parking.
Public Rights of Way include footpaths, bridleways, restricted byways, and byways open to all traffic (BOATs). They are all highways, and are shown on Definitive Maps.
