highway network, it is necessary at times to implement Temporary Traffc Management (TTM) measures to facilitate road works, temporary closures or incident management.Work Zones on or near a road may affect the safety and limit the free movement of road users through and in the vicinity of the Work Zone.t is therefore particularly important to plan all works activities to optimize road safety, road space and work effciency whilst minimizing congestion, delay and inconvenience for all road users.All planned works on roads accessible to the public that will have an effect on the operation of the road require a Traffc Diversion Plan (TDP) to be prepared in accordance with this Guide.The TDP consists of a set of documents produced by the agency proposing the works, or their contractor, that details the processes to be followed for a specifc Work Zone to plan, gain approval, implement, maintain and clear TTM devices associated with that Work Zone in a safe and effective manner.!"7$ *3/4895:$;:24/:429Following this introductory Chapter, this document is divided into fve further Chapters: Chapter 2 defnes the principles of Temporary Traffc Management, explains how to classify works according to activity, road type and duration, and provides a framework for developing a Traffc Diversion Plan (TDP); Chapter 3 describes the detailed processes to be followed in the planning, implementation, monitoring and decommissioning of temporary traffc management.t describes the interface with the QPro system and how to submit a Traffc Diversion Plan for approval; Chapter 4 defnes the principles that must be applied to the implementation of Work Zones to ensure an acceptable level of safety;Chapter 5 provides a detailed description of the Traffc Control Devices, delineation devices and other devices and equipment specifcally associated with Work Zones, and provides instructions for their deployment; and Chapter 6 gives a number of Typical Layouts, mainly for long-term works, that can be used or adapted to provide a Traffc Management Drawing for a specifc Work Zone.Specifc layouts are provided for Mobile and Short and Medium term works.These are only to be used following a site-specifc risk assessment that departure from full static TTM is acceptable.!"9/:?@9$3A$:B9$C4?69The objective of this Guide is to provide all agencies, authorities, consultants and contractors engaged in work on or alongside the road with clear and comprehensive guidance on temporary traffc management measures to ensure:Safe and effcient passage of vehicles and other road users though road works; andSafe work environments for road workers whilst minimizing disruption in the adjoining road network.This Guide describes the temporary traffc measures that shall be used at Work Zones on all public roads to warn, instruct and guide road users in the safe negotiation through or around the Work Zone.t also describes the special signs to be used at Work Zones, and the processes that must be followed to ensure compliance.The purpose of TTM is to provide a road environment that is safe for all road users and workers during construction works, while maintaining access and traffc fow.Application of the principles detailed in this Guide will provide a uniform high standard of traffc control at Work Zones.1.2Qatar Work Zone Traffc Management Guide1.21.21.2Each Work Zone may have unique elements that will require the application of good engineering judgment.This Guide provides a set of principles for signing and delineation that will promote the safety of both the road user and road worker.The uniform and consistent treatment of similar hazards at Work Zones by the application of standardized layouts will promote safety by assisting road users in identifying potential hazards and negotiating safe passage through or around the works.1.4PrincipIes of Temporary Traffic Management - RESPECTThe purpose of Temporary Traffc Management is to warn and guide vehicles and other road users safely and effciently through work areas whilst providing protection to road workers.The following principles should be applied at all Work Zones: Responsibility to all road users;Elimination or management of conficts;Speed limits should be appropriate for the site-specifc condition; Protection of the workforce by use of appropriate safety buffers, PPE and training; Early warning of any obstructions ahead;Clear direction to all road users; andTraffc Control Devices to be designed and used in accordance with the Qatar Traffc Manual; To ensure a uniform approach to TTM, it is essential that all agencies and individuals associated with the planning, approval, implementation, inspection, enforcement and clearance of Work Zones understand and apply these principles in all stages of the Work Zone process. 1.5ContractuaI RequirementsThis document sets out a code of practice that shall be followed by any agency, designer, contractor or sub-contractor involved in the planning, approval, implementation, maintenance or removal of works on a public road.Any agency responsible for commissioning works on roads to which the public have access should make compliance with this document a condition of contract in the case of works carried out on their behalf, and any bid that does not include an element of cost for the Work Zone Traffc Management process is rejected. A sample contract clause is contained in Appendix B.The guidelines contained in this document are specifcally directed to establishing and maintaining a safe environment for road users and the workforce within Work Zones.However, they should be considered supplementary to the Occupational Safety and Health requirements as set out in the QCS.1.6DefinitionsFor the purposes of this document: "Shall or "must indicates that a particular requirement is mandatory;"Should indicates a recommendation; and"May indicates an option.Qatar Work Zone Traffc Management Guide1.31.31.7GIossaryTable 1.1 provides defnitions as applied to various terms used within this document: TabIe 1.1- GeneraI Traffic Management DefinitionsCarriageway The area of a Road that is specifcally for vehicular use, generally separated from adjacent verges, medians and footways by a curb.Carriageways may include cycle lanes where they are at the same levelClearance Plan A document that forms part of a TDP that includes a Method Statement outlining safe working practices and methodologies for the clearance of TTM.Clear Zone The roadside area adjacent to the nearest traffc lane available for safe use by errant vehicles.This area must be relatively fat, kept clear of non-frangible hazards and free of workers.Diversionary Route A temporary change in route in order to close a road or because of continuing unacceptable levels of congestion.
