As demand approaches the capacity of a road (or of the intersections along the road), extreme traffic congestion sets in. When vehicles are fully stopped for periods of time, this is known as a traffic jam [3] [4] or (informally) a traffic snarl-up [5] [6] or a tailback. [7] Drivers can become frustrated and engage in road rage. Drivers and ...
Traffic Cam. Traffic reporting is the near real-time distribution of information about road conditions such as traffic congestion, detours, and traffic collisions. The reports help drivers anticipate and avoid traffic problems. Traffic reports, especially in cities, may also report on major delays to mass transit that does not necessarily ...
The telcon usually includes the Operations Plan (OP), equipment outages, internal initiatives, terminal constraints, route closure/recovery information, anticipated Traffic Management Initiatives (TMI) necessary to manage the system, and/or other issues which may impact operations (such as staffing or special events).

Defensive driving describes the practice of anticipating dangerous situations, despite adverse conditions or the mistakes of others when operating a motor vehicle. [ 1 ] [ a ] It can be achieved by adhering to general guidelines, such as keeping a two- or three-second gap between the driver's vehicle and the vehicle in front to ensure adequate ...
Transportation forecasting is the attempt of estimating the number of vehicles or people that will use a specific transportation facility in the future. For instance, a forecast may estimate the number of vehicles on a planned road or bridge, the ridership on a railway line, the number of passengers visiting an airport, or the number of ships calling on a seaport.
In transportation engineering, traffic flow is the study of interactions between travellers (including pedestrians, cyclists, drivers, and their vehicles) and infrastructure (including highways, signage, and traffic control devices), with the aim of understanding and developing an optimal transport network with efficient movement of traffic and minimal traffic congestion problems.
Evening traffic on the A1 freeway in Slovenia. Transportation demand management or travel demand management (TDM) is the application of strategies and policies to increase the efficiency of transportation systems, that reduce travel demand, or to redistribute this demand in space or in time.
Level of service (LOS) is a qualitative measure used to relate the quality of motor vehicle traffic service. LOS is used to analyze roadways and intersections by categorizing traffic flow and assigning quality levels of traffic based on performance measure like vehicle speed, density, congestion, etc.
