Abstract: Electronic bus stop system was designed and developed based on the method of cloud computing by demand analysis of traditional and commercial electronic bus stop. Specific functions and demands of the system were analyzed in details. The functional designs of the core part such as the bus-stop board, data communication and data center visit were given. GWT technology was used in the Google cloud computing platform. The functions of the bus auto-reporter-calling system and display were realized, and the inaccurate problems existing in traditional electronic bus stops were solved effectively
