Prioritising level crossings in Melbourne for grade separation

The need to prioritise Melbourne's level crossings for grade separation results from the Victorian Transport Plan providing $440m for such projects, and train patronage and forecast train volumes growing strongly. A four stage prioritisation process was adopted that involved progressive elimination of the 176 crossings to arrive at 5-7 candidate projects to consider for thorough (business case) assessment. These stages required a number of assessment tools to be developed. To support this study the Australian Road Research Board was commissioned to develop a method for quantifying the safety benefit of grade separations that more comprehensively accounts for rail related costs. A Multi Criteria Assessment model was developed that takes into account the significant number of criteria that affect assessment of grade separation proposals. Work was also conducted to identify an economical, and acceptably reliable, means of estimating the travel time savings due to grade separations. Two factors had a strong bearing on the outcome of the prioritisation process: the very high train volumes forecast on some lines and the presence of tram tracks on some crossings. The study identified a short list of crossings for thorough assessment, a number of crossings where future options need to be protected through land use management, and a further group requiring additional study before the contribution of the level crossing to traffic congestion could be identified.
