A wide moving jam is a moving traffic jam, which exhibits the characteristic jam feature [J] to propagate through any bottlenecks while maintaining the mean velocity of the downstream jam front denoted by . Kerner's jam feature [J] can be explained as follows.
In contrast, the outflow of a wide moving jam determines a condition for the existence of the wide moving jam, i.e., the traffic phase J while the jam propagates in free flow: Indeed, if the jam propagates through free-flow (i.e., both upstream and downstream of the jam free flows occur), then a wide moving jam can persist, only when the jam ...
The scope of application ranges from various issues of traffic engineering (transport engineering, [2] transportation planning, signal timing), public transport, urban planning over fire protection (evacuation simulation) to 3d visualization (computer animation, architectural animation) for illustrative purpose and communication to the general public.
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.
Traffic waves travel backwards relative to the cars themselves. [1] Relative to a fixed spot on the road the wave can move with, or against the traffic, or even be stationary (when the wave moves away from the traffic with exactly the same speed as the traffic). Traffic waves are a type of traffic jam.
The China National Highway 110 traffic jam was a recurring [1] traffic jam that began to form on 14 August 2010, mostly on China National Highway 110 (G110) and the Beijing–Tibet expressway (G6), in Hebei and Inner Mongolia. [2] [3] The traffic jam slowed thousands of vehicles for more than 100 kilometers (60 mi) and lasted for 12 days.
A traffic bottleneck is a localized disruption of vehicular traffic on a street, road, or highway. As opposed to a traffic jam, a bottleneck is a result of a specific physical condition, often the design of the road, badly timed traffic lights, or sharp curves. They can also be caused by temporary situations, such as vehicular accidents.
A traffic jam is a colloquial term for traffic congestion. Traffic jam may also refer to: Traffic Jam, a 1979 Italian film "Traffic Jam" (Malcolm in the Middle episode) "Traffic Jam" (King of the Hill episode) "Traffic Jam", a song by "Weird Al" Yankovic from the album Alapalooza "Traffic Jam", a song by Bappi Lahiri from the Hindi film Rock ...
