context_page_description: A smart motorway, also known in Scotland as an intelligent transport system, is a section of motorway that uses active traffic management techniques to increase capacity by use of variable speed limits and hard shoulder running at busy times. Benefits include smoother traffic flow, more reliable journey times, fewer road traffic collisions, and reduced noise and harmful vehicle emissions. The term controlled motorway is sometimes used for schemes that use variable speed limits without hard-shoulder running.
  As of 2019, smart motorways are mainly found in Great Britain, although the concept is also becoming common in Australia and New Zealand and some parts of Switzerland.
