This presentation discusses how to improve the resilience of London's transport network to climate change, focusing on the Futurenet project and other recent work. It outlines the assessment of vulnerabilities, risk assessment, adaptation options, and implementation and monitoring. The presentation also highlights the importance of data inputs, identifying vulnerable areas, and maintenance strategies. Additionally, it explores the impacts of climate change on pavements and provides recommendations for improving resilience. Finally, it examines the optimization of tyre and road surface interactions for skid resistance and its effects on climate change resilience.

  1. How can we make London’s transport network resilient to climate change? Insert the title of your presentation here Presented by Name HereJob Title - Date Presented by Jacquie Berry16/11/10

  2. Presentation outline 1 Climate Change Adaptation 2 Improving the resilience of transport 3 Futurenet 4 Other recent work 5 Conclusions Page 2

  3. Climate change resilience in London TfL reporting under the Adaptation Reporting Power Draft Mayor’s Climate Change Adaptation Strategy Assessing resilience of assets and operations Action plans to improve resilience

  4. Improving the resilience of transport Determine impact of past weather events and identify vulnerabilities Identify thresholds Risk assessment – identify likely future impacts Assess adaptation options and prioritise (technical solutions/tailored asset management) Implementation and monitoring Highways Agency’s Adaptation Framework Model

  5. Future resilient transport networks http://www.arcc-futurenet.org.uk/

  6. Project details EPSRC “Adaptation and resilience to climate change” (ARCC) programme Project runs from June 2009 to March 2013 Six partners led by the University of Birmingham

  7. The key questions What will be the nature of the UK transport system in 2050 both in terms of its physical characteristics and its usage? What will be the shape of the transport network in 2050 that will be most resilient to climate change?

  8. Project scope Model 2050 transport system taking into account changes in infrastructure, technology, demographics and climate Travel demand and users decision making Transport network as a whole and interactions between modes Combines expertise on climate, engineering, travel behaviour, geology and hydrology Outputs will help decision makers improve resilience

  9. London to Glasgow Transport Corridor High volume of road, rail and air traffic Large variation in climate Variety of climate change impacts Strategically important route

  10. Modelling approach • Three levels • Corridor model • Integrated models • Individual failure models • Aimed at different user groups • Different levels of detail

  11. Data inputs for models Geology Topography Hydrology Asset information Traffic flow

  12. Asset data Liaison with key stakeholders Location (GPS) Type of pavement Slope and height of embankments Capacity of culverts Condition

  13. Vulnerable areas • Identify vulnerable areas • Use past events to predict future areas of vulnerability • Include: • diversionary routes • access to stations, airports, depots, control centres • contingency plans

  14. Issues identified to-date Lack of information recorded on past weather events Accurate and comprehensive asset data often missing Importance of looking at the wider picture Difficulties in using maintenance data for assessing resilience

  15. Project 2: Maintaining Pavements in a Changing Climate

  16. Project details • DfTfunded project on behalf of the Roads Board • Guidance for local highway engineers on climate change impacts on pavements • Sister document to Well-maintained Highways • Accompanying technical report The effects of climate change on highway pavements and how to minimise them

  17. Climate change impacts on pavements Used UKCIP02 scenarios to look at how changes in climate variables would influence deterioration of pavements Collected case studies of the impacts of past weather events on local highways Performance of different types of pavement materials and designs in the climate projected for 2050 Provided advice on improving resilience

  18. Findings Highway authorities need to assess network vulnerability to climate change Use local knowledge of assets and past events to assess risk Inadequate condition, whether as a result of poor design, construction or maintenance increases risk Combination of climate and other factors can cause damage Technical recommendations were given

  19. Project 3: Tyre and Road Surface Optimisation for Skid resistance and Further Effects http://tyrosafe.fehrl.org/

  20. Project details • Funded by EC FP7 • Objectives • to prepare for European harmonisation • to optimise the assessment and management of essential tyre/road interaction parameters • Climate change impacts on tyre/road interaction • How optimisation affects resilience

  21. Skid resistance and climate change • High temperatures • Fatting up • Embedment • Intense rainfall • Aquaplaning • Drier summers • Increased polishing • Greater build-up of contaminants • Seasonal weather patterns • Changes in seasonal variation of skid resistance

  22. Findings Properties of pavements and tyres vary with temperature and precipitation affecting tyre/road surface interaction There are direct and indirect effects of climate change on tyre/road interactions Optimising for skid resistance, noise and rolling resistance often improves climate change resilience

  23. Conclusions Better understanding of how climate change impacts affect the network and how this impacts on whole transport network Futurenet is modelling the future UK transport system relating detailed failure models to overall network resilience DfT technical guidance on the impacts of climate change and adaptation actions TYROSAFE looked at the impacts of climate change on tyre/road surface interaction Building our knowledge of how climate change affects transport and how to make the network more resilient
