As part of the government scheme, smart motorways actively manage traffic flows to develop and organise the motorway network. What else is there to know about this optimised way of driving?

What is a smart motorway?

A smart motorway utilises technologies to monitor and respond to wavering traffic conditions. They are currently designed and installed across numerous motorway systems and first appeared on the M42 in 2006. As part of the government scheme, smart motorways increase the aptitude of the general motorway and avoid the need to build additional lanes. There are three main types; controlled, hard shoulder running and all lane running.

There are a number of planned roadworks in 2017.

Why do drivers need smart motorways?

According to an array of studies and research, the economic impacts of congestion on the strategic road network are calculated to cost around £2 billion per year. This is likely to increase further due to the prediction of burgeoning traffic up to the year 2035. Although we’ve got a duration before we reach the ‘30’s’, the main aim of smart motorway technologies is to enhance journey times and manage traffic build up.

How do smart motorways work?

Smart motorways function by adopting various operation regimes to meet operational requirements on the road. These included the controlled motorway, the hard shoulder running and the all lane running.

Controlled motorway

Controlled motorways have three lanes (or more) with variable speed limits, however they retain a hard shoulder – this is only for use in genuine emergencies.

Hard shoulder running

Hard shoulder running uses the same systems as the controlled motorway in addition to actively managing the hard shoulder. This regime dynamically opens and closes the hard shoulder at peak periods to increase capacity allowing different levels of intervention, all depending on the conditions of the traffic.

All lane running

All lane running schemes on smart motorways are designed to permanently convert the hard shoulder into an additional running lane whilst operating with all lane features and systems associated with the controlled motorway.

Through junction running

The range of technologies include message signs, signals, CCTV cameras, vehicle detection and speed limit enforcement. These various motorway features work to provide information to motorists with road conditions ahead and variable mandatory speed limits. These features all contribute to the success of safe motorway control.

How to stay safe on a smart motorway:

  • Never drive in a lane closed by a red “X”
  • Don’t drive in the hard shoulder (indicated with a white solid line) unless directed
  • Keep to the speed limit shown on the gantries
  • Use refuge areas for emergencies if there is no hards shoulder
