Abstract-On-line surveillance to improve safety and security is a major requirement for the management of public transport networks and other public places. The surveillance task is a complex one involving people, management procedures, and technology. This paper describes an architecture that takes into account the distributed nature of the detection processes and the need to allow for different types of devices and actuators. This was part of a major European initiative on intelligent transport systems. Because of the dominant nature of closed circuit television in surveillance, this paper describes in detail a computer-vision module used in the system and its particular ability to detect situations of interest in busy conditions. The system components have been implemented, integrated, and tested in real metropolitan railway environments and are considered to be the first step toward providing ambient intelligence in such complex scenarios. Results are presented that not only deal with detection performance, but also on the perception of people who used the system on its effectiveness and potential impact.

This paper presents a real time surveillance system that can be deployed within public transport environments. The system is a fully customisable application that can be used to address the requirements for this application domain. The system has been under trial on a number of metropolitan railway systems in the UK and Italy. In this paper we discuss how some of the algorithms employed within the system can be adapted for use with the CREDS datasets.
