Project title RAIN - Risk Analysis of Infrastructure Networks in response to extreme weather
Summary In recent years, a variety of extreme weather events, including droughts, rain induced landslides, river floods, winter storms, wildfire, and hurricanes, have threatened and damaged many different regions across Europe and worldwide. These events can have a devastating impact on critical infrastructure systems. The RAIN vision is to develop a systematic risk management framework that explicitly considers the impacts of extreme weather events on critical infrastructure and develops a series of mitigation tools to enhance the security of the pan-European infrastructure network. This project will quantify the complex interactions between weather events and land based infrastructure systems. The output of RAIN will aid decision making in the long term, securing new robust infrastructure development and protection of existing infrastructure against changing climates and increasingly more unpredictable weather patterns. Transport, energy and telecommunications infrastructure will all be considered and risk mitigation strategies will be developed. This will be achieved through developing an operational analysis framework that considers the impact of individual hazards on specific infrastructure systems and the coupled interdependencies of critical infrastructure through robust risk and uncertainty modelling. The framework will consider cascading hazards, cascading effects and time dependent vulnerability with the ultimate objective to develop practical software tools and guidelines that provide support to European infrastructure managers in the event of an extreme weather event occurring and to minimise the impact of extreme events by developing mitigation and response strategies. RAIN will facilitate a cross-European collaborative platform, supported by the necessary tools and methodologies, where relevant stakeholders can share data, results of model simulations, and operational strategies in a seamless, efficient, and effective way. Technical and Logistic solutions will be developed to minimise the impact of these extreme events, which will include novel early warning systems, decision support tools and engineering solutions to ensure rapid reinstatement of the infrastructure network. These tools will be implemented within a novel Europe-wide operational and response strategy that will emerge from this research. The ability of this response plan to cut across borders will be guaranteed by the pan - European multi-disciplinary consortium. This project is being led by Trinity College Dublin. The project partners include: European Sever Storms Laboratory, Zilinska Univerzita V Ziline, Technische Universiteit Delft, Gavin and Doherty Geosolutions Ltd., Dragados SA, Freie Universitaet Berlin, Roughan & O' Donovan Ltd., Hellenberg International OY, Istituto di Sociologia Internazionale di Gorizia I.S.I.G, PSJ, Ilmatieteen Laitos,, Union Fenosa Distribucion SA and Aplicaciones En Informatica Avanzada SL.

Project title Base lining Road Works Safety on European Roads (BRoWSER)
Summary The central concept for the BRoWSER project is that provision of accurate, timely and consistent road worker accident data will enable national road authorities to drive down road worker risks and monitor the associated improvements in safety achieved. These hypotheses will provide evidence to either support or refute the need for a European Road Worker Casualty (EuRoWCAS) data source and for change towards a position of consistency for road works signing across the EU. This will deliver a structure for delivery of consistent information (and a road worker data collection toolkit) for use by national road authorities that can be used within the trans-national community to identify common and country-specific risks. This will enable better management of road worker risk across Europe, allowing for co-ordinated and structured action to be taken by national road authorities to solve common problems associated with road worker risk. It will also ensure that road users experience a common approach, reducing their risk during journeys within the EU.

Project title Measuring the acceptance of wind farms in Ireland
Summary It is envisioned that wind energy will play a key role in realising our national government targets of 40 % renewable electricity by 2020. In order to achieve this it is important that we better understand individuals perceptions, concerns and reservations on the construction of wind farms. Like the construction of any new infrastructure such as; roads, new housing/ industrial developments, or waste disposal facilities, it is important to have positive public participation from the beginning of the project. This project will seek to determine the most appropriate methodologies to measure social acceptance of wind energy projects updating the previous studies undertaken in 2003. In previous studies mainly positive attitudes were found towards the development of wind farms both among the general Irish population and particularly among those who live in a community where a wind farm is already situated. This gave a very positive background against which future development grew. Now however it is important to reassess the level of current social acceptance, following nine years in which wind farm developments in Ireland have increased substantially and will do so more rapidly in future in order to fulfill our national 2020 targets.

Project title Peacox – persuasive advisor for CO2-redcing cross-modal trip planning
Summary Ecological issues in urban traffic become more and more pressing as personal transportation is one of the greatest contributors of CO2 emissions. Means to help people reducing their ecological impact are needed urgently. To answer this need Ecological Aware Navigation provides urban travellers with personalized navigation tools that allow, help and persuade them to travel and drive more eco-friendly. To convince users in making more sustainable travel choices Ecological Aware Navigation will enrich navigation systems with innovative approaches and features. The system will be developed in two iterations following user-centred and agile design approaches, and extensive field trials in Vienna and Dublin will ensure high quality and impact of the developed system. The consortium unites expertise from navigation systems, transportation sciences, environmental modelling, artificial intelligence, human-computer interaction to software development. Project partners include: CURE – Center for Usability Research and Engineering, Fluidtime Design Software Service, Telematix Software, a.s., ETH Zurich Swiss Federal Institute of Technology Zurich Institute for Transport Planning and Systems, National Technical University of Athens - Institute of Information and Computer and Communication Systems, Verkehrsverbund Ost-Region VORG mbH/ ITS, Vienna Region and TomTom International BV.

Project title National Cycle Network – Route Feasibility and Delivery Study
Summary In 2009, the first National Cycling Policy Framework was adopted. This set clear and ambitious targets for the country. One component of this framework is an interurban cycle network that will be attractive to commuters, tourists and leisure cyclists. The NRA is currently engaged with several state agencies to coordinate the implementation of Objective 3 outlined in the National Cycle Policy Framework, which is to “Provide designated rural cycle networks especially for visitors and recreational cycling”. The NRA is currently concentrating on one element of this objective, which is the route selection and feasibility study for the corridor between Dublin and Galway. This corridor is split into three distinct sections. The research conducted in this project will include a route selection analysis and the second section of the research will involve producing design standards for interurban cycle lanes in Ireland.
