Title Departure side platforms as a measure to mitigate level crossing road closures: an investigative study using simulation modelling

Abstract This thesis investigates the impact of level crossings closures on traffic congestion at level crossings adjacent to or in the close proximity of railway stations, proposing that making alterations to the infrastructure of the station can derive a reduction of intersection closure periods at these locations. These infrastructure alterations relate to the platform arrangements at stations, and present an opportunity to mitigate the time of roads closure periods at level crossing, thus alleviating road traffic congestion.

To test this proposition, a case is used in the city of Melbourne, in Victoria, Australia. The station environment at one station on the Melbourne rail network is simulated using traffic simulation software that allows the user total control of the environment and the transport network emulated, including vehicles types, traffic composition, intersection controls and the general environment. The simulation process is conducted in two phases, one to emulate the current environment and the other to emulate the proposed environment; the results from each of the simulation processes are then compared to ascertain the differences achieved.

Simulation results testing single, two-train and multiple-train arrivals and departures at the current and proposed environment, confirmed the proposition that the platform repositioning approach can be used to mitigate road traffic congestion at level crossings railway stations precinct. This has led to the development of the theory of Departure Side Platforms (DSP). Further, results confirm, using three different road traffic volume levels, that the theory works when both single and multiple train arrivals and departures are in operation at the level crossing. The simulation results also confirmed that under the proposed platform environment, continual level crossing closures of more than two trains would no longer occur.
