![]() ![]() This congestion is repeated on a daily or weekly basis and is referred to as recurring congestion. A large proportion is attributable to road bottlenecks and poor signal timing (40% and 5% of all congestion in this example). The results, averaged for all roadways, are shown in the Figure below. Some years ago, a study in the USA set out to quantify the leading causes of traffic congestion. border control for both passengers and cargo (See Border Clearance).pollution minimisation ( See References for this page).road weather management ( See Weather Management).freight management ( See Operations & Fleet Management).parking management ( See References for this page).preferential treatment for specific vehicle types – for example passenger transport and car sharing ( See Highway Traffic).tidal flow (directional lane control) ( See Urban Networks).route guidance ( See Pre-tip/ On-trip Information).part-time measures – for example seasonally-related ‘Park & Ride’.bus and transit priority systems (See Bus / Tram Signal Priority).traffic signal and urban arterial management (including adaptive signal control) ( See Urban Networks).traveller information services (See Travel Information Systems).traffic incident management ( See Traffic Incidents).Some examples of traffic management measures that may feature as part of a network operating strategy are: These may include restrictions on the free use of individual vehicles through Electronic Road Pricing (ERP) or a Congestion Charge. When traffic control systems have been found to reach their limits and where adding capacity or new building of road infrastructure is not feasible, further measures may become necessary. These features are starting to be deployed amongst established traffic management systems. Examples include bus and tram priority, and pollution monitoring. The emergence of ITS in the field of traffic control has enabled a number of new concepts to be applied in the framework of innovative operational systems. These measures make use of ITS systems, services and projects in day-to-day operations that impact on road network performance.Ĭentral to this approach is the development and integration of a set of traffic management measures appropriate to the local and regional requirements – and to achieve this through a planning process that makes use of systems engineering, standardisation and documentation, and performance management. Traffic Management refers to the combination of measures that serve to preserve traffic capacity and improve the security, safety and reliability of the overall road transport system. See section 18.6.3 of the OHS Regulation for more details.Authors Charlie Wallace and Greg Speier (Courage & Wallace, USA) John Miles (Editor) Traffic assistants can be trained by their employers, as long as the training addresses the hazards specific to the workplace and includes coursework and a practical component. Traffic control work in lower risk locations - such as parking lots and vessel loading areas - can be done by a traffic assistant. BeeSafe - a division of WorksafeT Solutions Inc.WorkSafeBC only considers training offered by the following providers as meeting acceptable standards and requirements: To WorkSafeBC standards as specified in the latest edition of the Traffic Management Manual for Work on Roadways (the Traffic Management Manual).Traffic control persons (TCPs) must be trained: Employers must ensure a risk assessment is conducted by a qualified person to determine if traffic control persons (TCPs) will be used. ![]()
