Application of 2-D Barcode Technology in Highway and Bridge ETC System

With a very high data capacity and density feature, two dimensional bar code can not only used for error detection but also error correction. These advantages can be used to solve the problems effectively in the vehicle management and highway/bridge ETC (Electronic Toll Collection). This paper firstly analyses the application of two dimensional bar code technology in ETC system, and proposes a solution to solve the problems, then gives a description of system components in detailed and design the content of the bar code. Finally, the paper analyses the potential of the system.
