Braidwood Associates was invited by Steer Davies Gleave to lead the microsimulation traffic modelling development of the Queens Quay, Clydebank project on behalf of FM Developments.
The project involves the redevelopment of the former shipyard, where ocean liners such as the Queen Mary and Queeen Elizabeth I and II were built. The shipyard had a reputation as one of the world's greatest and its history is reflected in the name of the development, Queens' Quay.
The £250m redevelopment involves the regeneration of the site to include commercial, residential, retail and educational facilities.
The microsimulation modelled study area includes the main A814 corridor in Clydebank between the Agamemnon St/Boquharan Rd junction to the west and North Elgin St to the east.
The aim of the study was to develop a 2007 base year model of the study area to be used firstly to assess the overall impact of different junction layouts implemented as part of the master plan development.
Trip matrices were then developed for three time periods, AM (07:00-10:00), PM (16:00-19:00) and Saturday (11:00-16:00). Individual hourly matrices were developed for all three time periods with a 30 minute preload applied to all time periods to ensure that the network contained representative traffic flow at the beginning of the model analysis periods.
The model validation process has been carried out in accordance with the guidance criteria specified in the Design Manual for Roads and Bridges Volume 12.
Microsimulation traffic modelling was the obvious choice for this Transport Assessment (TA) as it allowed superior analysis of complex junction arrangements compared to traditional modelling packages. In addition to this, the visual output of the software assisted in communicating design issues to members of the project team and council officials.
