  • Abstract:

    The success of the United Kingdom’s implementation of sustainable development goals rely, to some extent, on the ability of the construction industry to develop resilient infrastructure, promote inclusive and sustainable industrialisation and foster innovation. Carbon emissions caused by both road transport and road construction are particular concerns as emissions continue to grow both in absolute terms and as a proportion of total emissions. In an attempt to tackle traffic congestion whilst deliv­er­ing improved environ­men­tal out­comes, smart motorways are becoming more prevalent through technology-driven approaches such as active traffic management (ATM) systems, hard shoulder management (HSM) systems and digital enforcement cameras. Such technologies are able to monitor and respond to fluctuating traffic conditions by altering the speed limit to smooth traf­fic flow, acti­vate warning signs to alert users of haz­ards up ahead and permit the use of the hard shoul­der, either perma­nently or at peak times.

    This paper investigates smart motorways as a way of reducing congestion and carbon emissions. Central to this, is the exploration of how such motorways are being managed; the drivers and barriers influencing their implementation and their contribution to sustainable infrastructure. This research is one of the first which deals specifically with the topic of smart motorways, where much of the focus to date has been on smart cities alone.
