The smart green tool for the government: The electronic vehicle identification in management of public bus services

As the number of vehicles running on the road increase, the traffic control becomes a serious problem in many historical cities, like Macao. Public transportation would hardly run and manage. In this research project, we propose the Electronic Vehicle Identification (EVI), which is a smart device with low-energy Bluetooth connection that exchanges the vehicle information and allows external communication with other control systems. As an ID for vehicle, it can be uniquely identified a vehicle and communication with vehicle is allowed. To illustrate the correctness of EVI, we conducted an experiment by using a Bluetooth reader to connect to EVI to discover the movement of bus vehicle departing or arriving at the bus terminal. e result shows that the bus vehicles can be captured on the road effectively, which can be used to support the Macao traffic department in optimizing road resources, managing traffic and making development plan.
