Objectives The project in this semester is an interdisciplinary project. It combines distributed systems design, computer science and computer networks. PDA based flexible ticket system You are going to implement a prototype of a flexible ticket system. In its complete version it is going to replace the current RF-id tag based system. The new system expected lifetime is 5 year only. In 5 years it is expected that face recognition has advanced sufficiently to allow ticketing based entirely on automatic unattended image processing. While the proposed system only partly reduces the manual control, it will reduce the amount of sign in /sign out equipment on platforms and placing that equipment entirely in the rolling stock. Each train compartment or bus is already e...
