The objective of the EWENT project is to assess the impacts and consequences of extreme weather events on EU transport system. These impacts will be monetised. EWENT will also evaluate the efficiency, applicability and finance needs for adoption and mitigation measures which will dampen and reduce the costs of weather impacts. The methodological approach is based on generic risk management framework that follows a standardised process from identification of hazardous phenomena (extreme weather), followed by impact assessment and closed by mitigation and risk control measures.
EWENT will start this by identifying the hazardous phenomena, their probability and consequences and proceed to assessing the expected economic losses caused by extreme weather when it impacts the European transport system, taking also into account the present and expected future quality of weather forecasting and warning services within Europe.

The project-specific objectives of EWENT are the following and they are studied accordingly step-by-step:

  1. Identification and definition of hazards on EU transport system caused by extreme weather phenomena and the development of most relevant scenarios.
  2. Estimation of the probabilities of risk scenarios caused by extreme weather phenomena; this is done by mode and time axis (operational vs. strategic risks).
  3. Estimation of impacts and consequences of hazards - based on empirical experiences and applied to scenarios - on EU transport infrastructure and operations; first on infrastructure, then on operations and finally on supply chains and mobility.
  4. Monetising harmful consequences per mode as a part of risk evaluation, both on infrastructure and operations (including mobility and supply chain impacts).
  5. Risk assessment based on impact evaluation and options for reduction and control of harmful events in short and long term. The latter viewpoint is focused on monitoring processes and public and private warning/alarm services on weather phenomena and the former is the starting point for planning and standard setting.
  6. The effectiveness analysis of different management and policy options. This includes the assessment of feasible options in terms of needed investments, intergovernmental co-operation, risk management tools and functional decision making processes. A cost effectiveness analysis is performed to prioritise the options.

The EWENT project includes 8 work Packages (WP). Figure 1 presents the EWENT assessment process and the Work Packages within.

EWENT will cover most transport modes but as an interesting add-in it will include light traffic as one mode. The transport system is viewed from three perspectives:

These views also adopt different time horizons, i.e. some risks are dealt with on day-to-day basis (how to prepare for and eliminate sudden extreme weather with short term measures) and some are strategic in nature (how to prepare on the long-term to face extreme phenomena, by e.g. changing the standards of transport infrastructure). An organisational and institutional view is taken when risk management can be dealt at local, national and pan-European levels
