CHORIST and the Early Warning

The CHORIST project is a 38 month project (June 2006 - July 2009), funded by the European Commission, which addresses Environmental Risk Management in relation to natural hazards and industrial accidents.

CHORIST proposes solutions to increase rapidity and effectiveness of interventions following a major natural and/or industrial disaster in order to enhance citizens' safety and communications between rescue actors.

Main features

The main objective of the CHORIST project is to develop a system made of the three following subsystems:

  • MODULE 1: A risk assessment report subsystem :
    A fully integrated, reliable and performing risk assessment report system processes inputs from heterogeneous sensors, disparate legacy monitoring and warning agencies, citizens through emergency call centers... in order to deliver alert messages to authorities.
    These alert messages are accompanied by a picture of the situation which is constantly updated.

  • MODULE 2: A warning message dissemination subsystem :
    This subsystem consists of heterogeneous communication means disseminating warning and alert messages in parallel from authorities to as many citizens as possible within the crisis area and with a limited delay. The selected media channels are:
    1. Digital Audio Broadcasting (DAB),
    2. Digital Video Broadcasting (DVB),
    3. GSM networks featuring the cell broadcast technology, and
    4. sirens.

  • MODULE 3: A rapidly deployable telecommunication subsystem :
    This subsystem soffer secured and interoperable voice and high data-rate services to in-the-field rescue response teams. Two complementary technologies are proposed:- WiMAX based ad-hoc networks and - A TETRA TEDS mobile base station)

CHORIST with the rest of the World

The pattern in such situations usually goes as follows:

  1. A crisis is detected at one or different local situation centres. Authorities are made aware of it.
  2. The authorities organise the appropriate response through local operational centres.
  3. The authorities also disseminate warning messages to citizens in the crisis zone and tell them how to behave.
  4. The response team is deployed according to pre-defined procedures and proceeds in reaction to risk evolution.

Project activities

The CHORIST project:

  1. Involved users (Civil Protection Authorities, citizens and telecommunication operators) all along the project life, in order get their requirements and their feedback on the ongoing technical developments;
  2. Derived technical requirements from the user inputs, then develop the three subsystems (alert chain subsystem, message dispatch subsystem and rapidly deployable subsystem) and finally integrate them into one CHORIST system;
  3. Set up a demonstration in Spain to validate the proposed concepts and assess performances;
  4. Promoted the project to the broader scientific and user community (knowledge dissemination, standardisation, impact assessment and exploitation)

Long term objectives (after 2010)

The long-term societal objectives beyond the project time frame are:

  1. To improve Emergency Risk Management through the integration of innovative and complementary communication technologies (radio, TV, GSM, siren networks, PMR networks, ad-hoc networks...);
  2. To increase rapidity and effectiveness of interventions in crisis areas (by means of a rapidly deployable TETRA TEDS base station, or a WiMAX ad-hoc network, both interoperable with existing PMR networks (for voice) and data networks);
  3. To enhance the safety of the citizens in crisis areas by improved information (improved = taking into account human behaviour and cultural issues), both to and from the citizens;
  4. To enhance the safety of the rescue actors.
