Vehicular communication systems are computer networks in which vehicles and roadside units are the communicating nodes, providing each other with information, such as safety warnings and traffic information. They can be effective in avoiding accidents and traffic congestion. Both types of nodes are dedicated short-range communications (DSRC
In 2010 the car manufacturer decided to have a button on the Sonata Hybrid's instrument panel to turn the VESS on and off, but after the enactment of the Pedestrian Safety Enhancement Act of 2010, signed into law by President Obama in early 2011, and learning that the U.S. National Highway Traffic Safety Administration would not allow such ...
Diagram showing how a car horn works. A horn grille is a part of some designs of car or other motor vehicle that has an electric horn, such as a motor scooter. Larger, louder air horns, as found on trucks (lorries) and buses, are driven by air compressors, or supplied by reservoirs charged to operate their air brakes. The compressor forces air ...
Reliability is a high priority in range safety systems, with extensive emphasis on redundancy and pre-launch testing. Range safety transmitters operate continuously at very high power levels to ensure a substantial link margin. The signal levels seen by the range safety receivers are checked before launch and monitored throughout flight to ...
Dedicated short-range communications (DSRC) is a technology for direct wireless exchange of vehicle-to-everything (V2X) and other intelligent transportation systems (ITS) data between vehicles, other road users (pedestrians, cyclists, etc.), and roadside infrastructure (traffic signals, electronic message signs, etc.).

Early examples of VST included safety glass, four-wheel hydraulic brakes, seat belts, and padded dashboards. In 1934, General Motors began a scientific approach to vehicle safety by conducting the first crash barrier test. Gradually, existing systems were stabilized, followed by the introduction of disc brakes and anti-lock braking systems.
