Executive Summary

ES1 Introduction

Highways England introduced the Health and Safety 5 Year Plan in October 2015 with the overarching aim that “no one should be harmed when travelling or working on the strategic road network”. This means there is a continuing need to significantly reduce health & safety risks to employees, eliminating employee fatalities and serious injuries and significantly reducing employee personal injury accidents and “near miss” incidents.

This Performance Specification, as part of the Traffic Technology Systems suite of documents, provides policy on the functionality and performance requirements for remote controlled Temporary Traffic Management (TTM) sign control systems equipment, to minimise installation costs, minimise maintenance and replacement costs, ensure equipment safety, reliability and durability and improve road worker safety and road user safety.

This Performance Specification is applicable to control systems for both fixed (post mounted) and portable (including trailer mounted and A frame mounted) remote controlled TTM signs.

This Performance Specification is supplementary to (but does not replace any elements of) existing legislation and guidance documents relating to:

traffic signs. temporary traffic management at road works. health, safety and wellbeing in the workplace.

ES2 Recommendations

This Performance Specification policy is to be implemented with immediate effect by all service providers.

2.27. When a link is selected, The Control System shall display a schematic or map illustrating the selected link in the context of the wider network and present the Sign Groups located within that link.

2.28. Sign Groups displayed on the schematic or map shall be labelled with their location and shall make use of colour or icons to illustrate their status overview and fault overview. Where a fault is present within the group, the most severe fault level shall be illustrated.



Page 11 of 14 Tues 04.10.16.

2.29. Sign Groups shall be selectable and, when selected, The Control System shall instigate a user initiate poll, outside the normal polling regime, for all signs configured within the selected group and display the status detail and fault overview for each sign.

2.30. Detailed fault detail for each sign shall be made available to the user.

2.31. Following selection of a Sign Group, the user shall be presented with a means of selecting a sign plan for application on the selected Sign Group. To assist identification of an appropriate plan, the system will provide a graphical representation of the selected sign plan.

2.32. When implementing a sign plan, the user shall be provided with an option to set the selected plan on the selected Sign Group.

2.33. Prior to the application of a sign plan on the selected Sign Group, a secondary confirmation shall be presented to the user, giving the option to abort or continue.

2.34. It shall not be possible to set an RCTTM sign individually. Signs shall only be set as part of an instruction to display a sign plan on a Sign Group.

2.35. When a user implements a sign plan on a Sign Group, prior to the application of that sign plan, The Control System shall instigate a poll, outside the normal polling regime, for all signs configured within the selected Sign Group. If a fault is reported by any sign in the selected Sign Group, the user shall be presented with an alert and given the option to review the fault detail, then either continue to implement the selected sign plan or abort the activity. This alert shall include the sign location and sign ID.

2.36. Available Sign Plans shall also include a plan comprising blank aspects to facilitate the ‘clearing’ of the display on all RCTTM signs in a Sign Group.

2.37. When a sign plan is already displayed, or no sign plan is displayed on a Sign Group, if a change in the fault status of any sign in that Sign Group is identified, the user shall be presented with an alert and given the option to review the fault detail. This alert shall include the sign location and sign ID.

2.38. The Control System shall provide indication to the user that both background and user initiated tasks are being performed.

Reporting 2.39. The Control System shall log all system and user events and store these for a period of no less than 60 months.

System Faults 2.40. Faults with The Control System shall not result in commands being issued to signs.
