Walsh-function-based CDMA solution for intelligent public traffic management system

Abstract

Identification and management of vehicles in a large and complex bus station require enough accuracy as well as high processing speed that traditional image-based solution is hard to achieve. This paper proposes a method using Walsh-function-based CDMA technology to realize vehicle identification and management. Attributing to the application of random wireless access, the system is more reliable and economical. Furthermore, due to the use of net database, intelligent management of vehicles is available. Characterized with sufficient flexibility, such system is especially appropriate for complex bus station.
