Integrating a modern light rail transit (LRT) system into an historic city centre

In June 2002 construction of the LUAS light rail system began in the historic city centre of Dublin. For this initial stage of the Dublin Transportation Office master plan, three lines are to be constructed consisting of on street, segregated and reserved track alignment. Within the city centre, this has meant the introduction of a 21st century track structure and highway design standards into a cityscape that dates back to the 18th century. While the city has a wealth of rich architecture and historic streets, this has left a legacy of obstructions and uneven roads that the track alignment must navigate. To overcome these problems, the latest track design and computer modelling techniques have been utilised to integrate the track alignment into the existing city infrastructure. The authors have used extensive CAD, vehicle motion software and 3D modelling techniques to develop the optimum alignment for the transport corridor. This has produced an integrated alignment for the LRT designed to accommodate all highway users. This has culminated in the production of an innovative integrated 3D model that has been used extensively for the systems design, visualisation and construction. This paper describes how the 3D model is developed from the initial 3D survey to its use on the construction site.
