Prioritising road-rail level crossings for grade separation using a multi-criteria approach
There are 177 at-grade rail road level crossings within Melbourne's metropolitan rail network. Each crossing represents a conflict point between trains and road traffic including cars, buses, trams, cyclists and pedestrians. Whilst the desire to eliminate level crossings is often based on safety needs, in the Melbourne context congestion is a major driver for grade separation. In particular it is the interaction between the crossings and neighbouring signalled junctions that is a significant contributor to congestion and a barrier to the efficient performance of the transport network. This conflict will be exacerbated by increasing train volumes: some crossings are forecast to carry nearly 40 trains per hour at peak times by 2021. This paper considers the assessment criteria available to prioritise metropolitan level crossings for grade separation. These include conventional economic, social and environmental measures as well as Melbourne specific 'strategic fit' criteria that reflect the relative importance of different roads to the transport network overall. In particular the paper discusses the challenges of data constraints, the weighting of quantitative versus qualitative indicators and the difficulties of accurately estimating the potential delay benefits from grade separations for a large range of sites.
