Design of a RFID-based speed monitoring system for road vehicles in Brunei Darussalam

A vehicle average speed monitoring system (ASMoS) design is proposed for speed management in Brunei Darussalam. This paper explains the principle of a RFID (Radio Frequency Identification)-based speed monitoring system, including all hardware and software considerations. Off-the-shelf industry standard RFID development kit is integrated with a Raspberry-Pi board as the Central Controller Unit (CCU). We adopt a two-point interrogation detection scheme for the calculation of speed over a known distance. Ultra high frequency (UHF) RFID transponders have been used for the proposed design as the key vehicle identifier. The CCU is responsible for establishing a Secure Sockets Layer (SSL) connection with a remote administration server for data storage. The aim of ASMoS is to assist road safety enforcement authorities to monitor and record speeding-related road traffic offences.
