The Rees Jeffreys Award, presented for the best paper on highway engineering, was awarded to Wright et al. (2016).

The formation of ice and snow on road pavement surfaces is a recurring problem, creating hazardous driving conditions, restricting public mobility as well as having adverse economic effects. It would be desirable to develop new and improved ways of modifying the pavement surface, to prevent or at least delay the build-up of ice and to weaken the pavement–ice bond, and making the ice which forms easier to remove. This development could lead to economic, environmental and safety benefits for winter service providers and road users. This paper describes how environmental scanning electron microscopy was used to examine the mechanism by which de-icing chemicals, added as a filler replacement to bituminous materials, can be transferred to the pavement surface. The paper assesses the potential for chemical modifications to reduce the adhesion between ice and the pavement surface by means of work of adhesion calculations, based on surface energy parameters and a new physical ice bond test. The paper also examines the influence that the chemical modifications have on the durability of the pavement surface course.

The William Webb Prize, awarded for the best paper on a transport- or rail-related subject, was awarded to Lucas et al. (2016).

Transport poverty is an issue that has never fully captured the interests of the transport engineering profession in either the ‘global north’ or ‘global south’ and yet it is a problem that adversely affects the daily lives of millions of people across the globe. What precisely constitutes transport poverty is not adequately articulated within academic, policy or infrastructure design literature. This paper aims to demonstrate how the different ways that academic studies and policy programmes have defined and recorded the problem of transport poverty is directly related to the ways in which it has been subsequently addressed in practice. The overall impression is one of inadequacy, fragmentation, inconsistency and tokenistic treatment of an issue that potentially affects anywhere between 10 to 90% of all households, depending on which definition is used and which country is being considered. This suggests that it is a far greater problem than the transport profession has previously been prepared to recognise and one that requires its urgent attention given the continuing trends for mass migration, urbanisation and wealth concentration within and between the ‘global north’ and ‘global south’.
