Road traffic collisions generally fall into one of five common types: Lane departure crashes, which occur when a driver leaves the lane they are in and collides with another vehicle or a roadside object. These include head-on collisions and roadway departure collisions. Collisions at junctions, including rear-end collision and angle or side impacts
A traffic collision in Japan, 2007 The aftermath of an accident involving a jackknifing truck, Mozambique, Africa. A traffic collision, also known as a motor vehicle collision, or car crash, occurs when a vehicle collides with another vehicle, pedestrian, animal, road debris, or other moving or stationary obstruction, such as a tree, pole or building.
A multiple-vehicle collision (colloquially known as a pileup or multi-car collision), [1] is a road traffic collision involving many vehicles. Generally occurring on high-capacity and high-speed routes such as freeways, they are one of the deadliest forms of traffic collisions. The most disastrous pileups have involved more than a hundred vehicles.
If the transmission medium is sensed busy before transmission, then the transmission is deferred for a random interval. This random interval reduces the likelihood that two or more nodes waiting to transmit will simultaneously begin transmission upon termination of the detected transmission, thus reducing the incidence of collision.
US statistics for 2005 show that roadway departure crashes resulted in 31% of fatal crashes, but were only 16% of all crashes. [4] Roadway departure collisions where the vehicle is sliding or spinning and runs broadside into a fixed obstacle are particularly dangerous since the vehicle doors and sides provide less protection to occupants than ...
Deer-vehicle collisions are surprisingly common in the United States, with 2.1 million occuring each year, accounting for 59,000 human injuries and 440 human deaths.
A local collision is a collision that occurs at the NIC, as opposed to on the wire. A NIC cannot detect local collisions without attempting to send information. On UTP cable, a local collision is detected on the local segment only when a station detects a signal on the RX pair at the same time it is sending on the TX pair. Since the two signals ...
The most recent figures available from NHTSA show that of 38,824 highway deaths in pandemic year 2020, 3,142 were due to distracted driving — less than 10%. NHTSA tallied 324,652 distracted ...
