Today every system has changed. I mean advancement of technology has changed everything. Not just advancements but it has also affected our lives and day to day activities. Today we are so dependent on technology that without it our day is incomplete. For example, if we take vehicles, earlier it was the property of only rich people poor were not able to own it so public sector transport saw major growth, but today we can see at least one vehicle in most of the houses.
Development of this sector has not only increased pollution has also led to major road accidents. Now the same technology has adopted some major solution for this. And that is vehicular communication system.
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. This communication system enables vehicles to wirelessly exchange information about their speed, location, and heading.
The technology can then employ visual, tactile, and audible alerts—or, a combination of these alerts—to warn drivers. These alerts allow drivers the ability to take action to avoid crashes.
Vehicles that could use this communication technology range from cars and trucks to buses and motorcycles.
The beginnings of vehicular communications go back to the 1970s. Work began on projects such as Electronic Route Guidance System (ERGS) and CACS in the United States and Japan respectively. While the term Inter-Vehicle Communications (IVC) began to circulate in the early 1980s.
The PATH project in the United States between 1986 and 1997 was an important breakthrough in vehicular communications projects. Projects related to vehicular communications in Europe were launched with the PROMETHEUS project between 1986 and 1995.
The main motivation for vehicular communication systems is safety and eliminating the excessive cost of traffic collisions.
This number of accidents can be significantly lowered by deploying local warning systems through vehicular communications.
Departing vehicles can inform other vehicles that they intend to depart the highway and arriving cars at intersections can send warning messages to other cars traversing that intersection. They can also notify when they intend to change lanes or if there is a traffic jam.vehicular communication systems could help avoid up to 79% of all traffic accidents.
