|REOST offers a new concept of railway safety through an observation, warning and decision control/support system to prevent derailing or other accidents. The core objective of REOST is to identify railway obstacles through optical sensing and fast Image Processing to follow operational action fast enough before reaching the obstacle location. REOST will trigger application and technical problem challenges in the field of Optical Sensing, fast Image Processing and automated response actions. Currently, there are no vision warning systems available in railway transport. Innovations in implementing the system relate to fast software based Image processing, day and night Optical sensing, automated decision control/support for fast response, use of communication means and integration between all subsystems. The REOST approach incorporates research into objects and obstacle definitions, Optical sensing to identify these obstacles, and fast Image Processing for automated decision support and action.
The objectives of REOST will be to perform the following:
1. Optical sensing recognition and identification system, assembled on the train front;
2. Safety requirements research and analysis to define objects measurement, object type or railway disorder character that will be categorised as a railway obstacle, thus imposing intervention on the train movement process;
3. Intervention process definition for each obstacle classification;
4. Wireless Image transmission process to a Control centre;
5. Option for Automated Decision Control/Support System;
6. Obstacle recognition at a minimum distance of 1,500 meters from the obstacle location;
7. Fast Response time (Maximum 12 seconds), which enables the right automated or manual action item long enough before crossing the railway obstacle.
First, the consortium handles the User Requirements and System Specifications including Safety Analysis, Architecture and Design. A quantitative risk assessment is performed: railway accidents and relevant causes are identified, together with the possible options for obstacles on the track. Strategies for risk reduction and RAMS objectives are identified. On the basis of the analysis of the User Needs the performance, parameters and characteristics of the systems are specified. According to the above specifications, the system architecture is determined and the system is designed. The core of the project includes the development of the optical module and of the software for image and data processing. Then, system integration and interfacing with the train communication system are performed, together with appropriate development of Human Computer Interface. Testing is performed both in-house and on the field. Field tests are arranged in two phases in order to implement in the second phase the improvements suggested by the results of the first phase, on the optical module and on the image processing software. Dissemination, exploitation and evaluation of the project results are dealt with in the respective workpackages.
