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
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

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
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?
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
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
Modelling approach
 Three levels
- Corridor model
- Integrated models
- Individual failure models
 Aimed at different user
groups
 Different levels of detail
Data inputs for models
 Geology
 Topography
 Hydrology
 Asset information
 Traffic flow
Asset data
 Liaison with key
stakeholders
 Location (GPS)
 Type of pavement
 Slope and height of
embankments
 Capacity of culverts
 Condition
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
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
Project 2: Maintaining Pavements in a
Changing Climate
Project details
 DfT funded 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
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
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
Project 3: Tyre and Road Surface
Optimisation for Skid resistance
and Further Effects
http://tyrosafe.fehrl.org/
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
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
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
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
