Originally, black boxes in airplanes perform routine gathering and storing of data on all airplane operations during fly time. In the event of a specific accident or crash, the log data can be analyzed to determine or clarify the causes of an incident.
A black box for cars is a video recording device with an acceleration sensor and a GPS receiver module. It can record any situation happening in front of a vehicle and store the information in the form of digital images into a built-in memory card. A vehicle’s black box is not a newly developed technology, but an application of existing video-recording technologies for the purpose of increasing road safety. This simple technology also has played a crucial role in solving or clarifying causes related to traffic crashes. Above all, the black box for vehicles has resulted in a decrease of traffic crashes, thus saving lives.
In South Korea, for example, taxi drivers first installed vehicles’ black boxes back in 2008. Since then, vehicle black boxes have been rapidly adopted by taxis throughout the country, under the sponsorship of local governments and insurance companies.
