Traffic congestion. A traffic jam in Istanbul, and an opportunity for two simit vendors to sell food to drivers. Traffic congestion is a condition in transport that is characterized by slower speeds, longer trip times, and increased vehicular queueing. Traffic congestion on urban road networks has increased substantially since the 1950s. [1]
A city or location posted on a series of traffic signs along a particular stretch of road indicating destinations on that route. Controlled-access highway, motorway, or freeway. A type of highway which has been designed for high-speed vehicular traffic, with all traffic flow and ingress/egress regulated. The corduroy.
Radar jamming and deception. Radar jamming and deception is a form of electronic countermeasures (ECMs) that intentionally sends out radio frequency signals to interfere with the operation of radar by saturating its receiver with noise or false information. Concepts that blanket the radar with signals so its display cannot be read are normally ...
Traffic flow. 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 ...
Level of service (transportation) 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.
Sig Alert. Sig alert, Sig-alert or Sigalert in California, as well as other parts of the United States, means an incident that significantly disrupts road traffic. The term was originally the name of a pioneering system of automated radio broadcasts regarding traffic conditions, introduced in the 1950s and named after its inventor, Loyd Sigmon.
In road-transport terminology, a lane departure warning system ( LDWS) is a mechanism designed to warn the driver when the vehicle begins to move out of its lane (unless a turn signal is on in that direction) on freeways and arterial roads. These systems are designed to minimize accidents by addressing the main causes of collisions: driver ...
When this collision condition is detected, the station stops transmitting that frame, transmits a jam signal, and then waits for a random time interval before trying to resend the frame. [1] CSMA/CD is a modification of pure carrier-sense multiple access (CSMA). CSMA/CD is used to improve CSMA performance by terminating transmission as soon as ...
