The Internet of Things (IoT), information and communication technology, and data mining technologies are three prime pillars of any smart city project. The intelligent urban transportation system is an indispensable part of any smart city and acts as a major contributor to a city's vitality. An extensive amount of vehicular information is being amassed by the wireless sensor networks (WSNs), vehicular ad hoc networks, and radio frequency identification (RFID)-based Intelligent Transportation System (ITS), which can provide an insightful image of various ITS issues concerning safety, security, and management. Merely depending on WSN and RFID predicated technologies for the construction of ITS is not adequate to realize the smart city dream in developing countries due to technological and monetary barriers. Considering this, an intelligent vigilare system for ITS is proposed, which sanctions network implementation without disrupting the current vehicular infrastructure through multifaceted modeling.
