The Automotive Industry Standard 140 commonly known as AIS 140, is a set of regulations published by the Automotive Research Association of India (ARAI) for all public transportation systems to build an Intelligent Transportation System in India.

This mandatory move came about when the Government realised the dire need of increasing efficiency in the transport sector of India. Thus, the Intelligent Transportation System (ITS) was born.

Under the ITS, traffic management and mitigation, public transport management, crisis management are taken care of. It is a globally proven system that allows the transport authority to gain control of the entire transportation movement in the country. The AIS guidelines were formulated as a consequence. AIS 140 guidelines are one among them.

According to the Automotive Industry Standard 140 (AIS 140), it is mandatory for all public transport and commercial vehicles to deploy vehicle tracking systems with camera surveillance and emergency buttons. The transport authorities are tasked with ensuring that all stipulated vehicles abide by the guidelines laid down by the standard.
