Abstract
The ARROWS (Advanced Research on Road Work Zone Safety Standards in Europe) handbook, aimed at improving the safety of road users and workers at road work zones, is intended for highway authorities, designers, contractors and other individuals and organisations responsible for traffic safety at roadworks. It is a product of the ARROWS research project, funded by the European Commission. The handbook is a pre-normative framework of recommendations, i.e. it is not intended to replace or supersede existing national official standards. The main focus of the handbook is the introduction of a common "best-practice" road road work zone design and operation. (A)
