The (old) Forth Road Bridge was the road bridge linking Scotland's capital city (Edinburgh) with the central-east part of the country. Corrosion problems detected in 2005 pushed forward the decision of building a new bridge in 2007, planned to be opened by 2016.
I assessed the future year scheme model options utilising various future year scenarios, junction optimisation and operation during traffic management conditions. I worked for more than a year in this project using S-Paramics, a microsimulation package.
