CROMATICA is concerned with the development and evaluation of telematic tools to allow improvement of security in public transport systems.

Setting the Scene

To increase the attractiveness of public transport there is a need to improve the service quality, which is characterised by the regularity and comfort of, as well as by the safety offered to passengers. For this reason, Metro operators have developed huge CCTV systems for monitoring public spaces in stations and for the detection of events that could potentially impact the quality of service. In general, several cameras are connected to one display and a limited number of staff is available for observation; much information is lost. It therefore seems that the use of automatic video image processing systems, which could assist operators and draw their attention to events of interest, could significantly contribute to increasing the efficiency of the CCTV networks.
CEA-LETI has already worked with RATP on the development of a portable link for video transmission.


A user-needs survey, conducted among metro and railway companies and airports, has led to the definition of a number of priority needs and to the specification of demonstrators which could answer needs such as:

-detection of potentially dangerous crowd phenomena
-fall on track detection
-detection of intrusion in forbidden areas, such as tunnels
-detection of abnormal lack of movement or counterflow movements in corridors
-detection of fights
-density and queue measurements
-routine data collection
-portable video link.

The first step was an evaluation of existing technologies already developed in the partners' laboratories. This evaluation led to the definition of improvements required for these technologies.
The subsequent step was to develop new equipment, capable of providing better solutions, and to build demonstrators.

Results and Achievements

Demonstrators have been built and set up in real conditions on three sites (ATM-Milano, LUL-London, RATP-Paris). Those demonstrators are dealing with the needs of video transmission and detection of abnormal specific or global behaviour.
In addition, a video library has been collected from many European transport networks, to allow a wide validation of telematic tools provided by the project.

Conclusions and Plans for the Future

The CROMATICA project has provided a collection of telematic tools dealing with security in Public Transport. With the exception of fight detection for which no tape was available, the solutions developed have been validated from a technical viewpoint on tapes and real world demonstrators.
Two types of tool integration will be necessary before industrialisation can start:
-in the area of "integrated" systems monitoring of public areas, in response to the specific needs of each operator
-in the "exploitation" procedures, which do not yet take this type of information into account.
These activities could be part of a follow-up project to CROMATICA, under the 5th Framework Programme
