In the context of increasing automation and the rise of smart vehicles, Indian roads still struggle to ensure safe transportation due to accidents caused by overspeeding and negligence of traffic rules. Speed limiting can be implemented with a single piece of code in the software for fully automatic and semi-automatic vehicles. In the Indian market, automatic vehicles are still a rarity due to issues of affordability and compatibility with local roads and terrains. This effective solution uses RFID technology and obstacle detection to implement a speed-limiting system on ordinary vehicles through a mounting device on the accelerator, without altering the existing internal infrastructure or hardware components of the vehicle. UHF RFID readers in vehicles read RFID tags placed at roadside points, which contain encrypted speed limit and location information to enforce speed limits. An auxiliary RFID unit is designed to create a foolproof system by storing the last read information from the primary speed-limiting system in a tag, which will be read at traffic checkpoints, thereby identifying malpractices and alerting authorities. Lower speeds can help avoid accidents or at least reduce the severity of accidents.
