42dot is an autonomous driving software and mobility platform development startup that has been developing Transportation as a Service (TaaS). The company develops all technologies and services related to movement optimized for people and logistics, such as autonomous driving technology, automatic delivery robots, drones, car sharing, vehicle calling, and smart logistics services. For example, 42dot uses artificial intelligence (AI) that integrates cameras, radars, and global navigation satellite systems (GNSS) to detect the surrounding environment, distance between cars, and speed. Then, the company has developed Level 4 self-driving technology that uses lightweight maps rather than high-precision maps. Through this technology, it has become the first certified public transportation system of Seoul City and is piloting self-driving cars. In addition, as the company was selected as Seoul's sole transportation platform operator that can drive autonomous vehicles from multiple companies, it also operates TAP!, an autonomous transportation platform that can operate even self-driving vehicles manufactured by other companies.
