Intelligent Transportation Management

Vehicle electronic identification, also known as the vehicle electronic ID card or digital standard information source for vehicles, commonly referred to as the “electronic license plate,” stores information such as license plate numbers within a radio frequency tag. It enables automatic, contactless, and non-stop vehicle identification and monitoring, representing an extension of passive radio frequency identification (RFID) technology within the Internet of Things (IoT) for smart transportation applications.
The electronic vehicle identification serves not only as an electronic license plate but also fulfills multiple functions. It incorporates annual inspection details, vehicle identification information, compulsory traffic insurance data, emissions compliance information, highway toll payment capabilities, and wallet functionality.
1.1 Key Features
Vehicle electronic identification, also known as “electronic license plates,” involves installing a chip on vehicles to enable real-time identification and dynamic monitoring of vehicle identities during high-speed movement. This technology also facilitates traffic flow monitoring, advancing intelligent urban traffic management. Its primary functions and roles can be summarized in four key points.

• Anti-counterfeiting: Each RFID tag possesses a globally unique TID number that cannot be altered, granting RFID technology unparalleled anti-counterfeiting capabilities.
• Anti-borrowing: Since vehicle license plate information can be encrypted and written into the tag, by accessing data from the system database, it is possible to determine whether a specific vehicle is authorized to use this permit (i.e., electronic tag). This prevents the unauthorized borrowing of permits, ensuring a one-to-one correspondence between permits and vehicles.
• Anti-theft Protection: If a vehicle permit is lost, the aforementioned methods can be used to verify whether a specific vehicle is authorized to use that permit based on the permit number and its uniqueness. The owner can also report the permit as lost. Should any vehicle attempt to enter or exit using a reported-lost permit, it will be identified.
• Tamper-proof: Each electronic tag is equipped with tamper-proof functionality. Once installed, the tag will cease to function if removed.

1.2 The Function of Electronic Tags

• Traffic violation detection, including speeding vehicles (section speed monitoring), red light running records, etc.
• Identification of counterfeit/cloned license plates
• Detection of vehicles driving against traffic on opposite lanes or one-way streets
• Restricted-plate/vehicle management and restricted-access vehicle control
• Bus lane recognition with bus priority enforcement, congestion pricing collection in urban core zones
• Road traffic congestion analysis and early warning, traffic distribution mapping, traffic planning contingency measures, and real-time traffic information dissemination
