ESR13 - Satellite Monitoring of Traffic Loading on Bridges - “Sat-Mon”

  • Project: “Sat-Mon” – Satellite Monitoring of Traffic Loading on Bridges
  • Host Institution: GDG
  • Address: Unit A2, Nutgrove Office Park, Dublin D14 X627, Ireland
  • Main Supervisor: Dr Paul Doherty (GDG) – Structures and Soil mechanics
  • ESR13 will register for PhD at UCD

Objectives

The goal is (1) to use satellite images to quantify the traffic loading on long-span bridges. The critical load condition for these bridges is congestion and the images will be analysed to determine the patterns of traffic during congestion – the gaps between trucks and the car/truck mixes. (2) Vehicle length will be found from the images and the correlation between length and weight will be used to estimate the loading on the bridge. The longest bridges in the world are currently designed using very simple approximations that assume long lines of trucks at minimum gaps. This project will revolutionise the way in which the loading on these bridges is considered.

Expected Results

A method of quantifying the traffic loading on long-span bridges that is much more accurate than anything currently available.

Expected Collaborations

Planned secondment(s) and Training offered: GDG will provide expertise with bridge engineering, bridge loading and soil-structure interactions. The partnership with strategic partners will provide:

  • RDS: image analysis training and research in collaboration with Department of Computer Science of UCD
  • ELAB: Advanced image analysis
  • HKPU: The field calibration and validation will be done at the Transport Department of the Government of Hong Kong Special Administrative Region in association with Hong Kong Polytechnic University.
