Ageing Infrastructure
1 in 5 local roads could fail in the next 5 years (ALARM 2018)
London sewer system, a triumph of Victorian engineering, dates back to 1868
3.1 billion litres (≈ 1,249 Olympic swimming pools) of UK’s water leaks every
day (Discover water)
52,547 mains water pipes burst in the UK Apr 2016 - Mar 2017 (Discover water)

Climate Change
Challenges for the transport sector – European Environment Agency (2014):
Increasing temperatures → increasing rail buckling & pavement deterioration
Weather extremes → floods or landslides leading to traffic delays, service
interruptions and detours … e.g. HGVs diverted onto minor, weaker roads
Sea-level rise → threatening harbours and other transport infrastructure
Changing wind patterns → air transport disruptions, flooding of airport
infrastructure and other weather events.

Limited ResourcesAnnual Local Authority Road Maintenance (2018)
In England and Wales the gap between the allocated budget in 2017/18 and
the required budget was £556 million
Having adequate funds and resources it would now take 14 years to get local
roads back into a reasonable steady state

Growing Populations
Over 50% of the world’s population lives in urban areas and this is expected to
increase by 1.5 times by 2045, adding 2 billion more urban residents

Resilience Through InnovationCritical Local Transport and Utility Infrastructure
Self-Repairing Cities – UoB Contribution
Aim: to improve the efficiency of infrastructure maintenance through a proactive approach by:
Detecting a defect at its early stages
Identifying and eliminating the defect’s main trigger(s), by considering the infrastructure systems interdependencies
Self-Repairing Cities – UoB Contribution
Benefits of a proactive approach:
Extended asset life
Reduced maintenance expenditure
Huge savings at the network level

Self-Repairing Cities – UoB Contribution
Benefits from robotic and automated systems:
Minimising human errors (image processing vs visual inspection)
Using geophysical technologies (e.g. GPR and ultrasound) where human access is:
Impossible (e.g. inside pipes) or
Undesirable (e.g. at height in the streetscape, in close proximity to vehicles on busy roads, in confined spaces)
Systematic monitoring over long periods (e.g. throughout overnight closures)
Eliminating or removing destructive methods
Enhancing the overall efficacy of maintenance systems
Self-Repairing Cities – UoB Contribution
We are developing a decision support system for these emerging robotic and autonomous systems.
This will enable autonomous decision-making by:
Suggesting the most appropriate geophysical and/or alternative method(s) for identifying defects (e.g. cracks in asphalt)
Establishing associated triggers (e.g. failed drainage, a leaking pipe, physical overloading, embrittled asphalt)
Suggesting alternative (robotic) repair methods, future maintenance regimes and future monitoring regimes (type, frequency)
Proposing appropriate quality control measures and establishing risks associated with future contextual change
