摘要：	Roadworks on the motorway and trunk road network generate traffic delays, often significantly greater than those which would have occurred had the road remained unobstructed. This results in costs to road operators and road users, as well as the economy as a whole. On the other hand, it is essential that the road network is maintained and updated. The key question is how that can be achieved while minimising the negative impact of the works. In order to address this question, it is necessary to gain an understanding of the processes which give rise to delay at roadworks. A large body of literature exists on roadworks and the effect they have on traffic movements and delay. By studying this literature, looking both at work on the impact of roadworks, and some of the measures proposed to mitigate that impact, it has been possible to gain an insight into the underlying causes of delay at roadworks. This report presents a review of currently available literature and attempts to bring together current understanding of the field.
