Introduction Designers and contractors should assess the risks involved in projects to develop systems of work that Carriageways can be dangerous places in which to present the lowest risks to workers and road users, for work and usually require some form of temporary each activity, in each specific road environment. traffic management to control and divert traffic around a work area. Those involved in setting out, maintaining Those doing the work must receive relevant and removing traffic management schemes are information, instruction and training to ensure they are particularly at risk as they work in a live traffic able to perform their assigned tasks and be provided environment.

This information sheet outlines the key factors to address when planning, managing and carrying out temporary traffic management operations .

It is not a comprehensive list of the management of the works. health and safety issues that may be encountered. Those designing and planning road works and traffic management layouts should: What the law requires n Consider: road layout, location of junctions and All work associated with establishing, altering, pedestrian crossings etc, whether permanent maintaining and removing static traffic management markings and signs will need to be altered or systems needs to be undertaken in ways that ensure removed, traffic flows, local attractions or events the health and safety of both workers and road users.

This requires that duty holders assess work-related risks and eliminate, reduce and control significant n Eliminate the need, where reasonably practicable, risks, so far as is reasonably practicable.
