2 Introduction Level Crossing Risk – Approximately 30% of rail related fatalities occur as a result of motor vehicle collisions 1 – Annual estimated cost to Australian society $116,279,817 ($2010) 2 – Over 23,500 level crossings, 8,838 public (67% with passive protection) 3 Rail Level Crossing Suite of Projects – R3.122 – Affordable Level Crossings – R2.121 – Low-cost RLX Risk & Legal Evaluation – R2.119 – Baseline RLX Video Level crossing accidents in Australia. Transport Safety Bulletin, Independent Transport Safety Regulator NSW Tooth & Balmford, RISSB Railway Level Crossing Incident Costing Model Level Crossing Stocktake, Railway Industry Safety and Standards Board, Australia

8 Limitations of Level Crossing Incident Analysis Number of level crossing collisions (lagging indicators) insignificant for data analysis Near-miss occurrences (leading indicators) – Occur with a frequency orders of magnitude greater than collisions – Reportable occurrences However, there are issues with current paper-based reporting – Under-reporting & inconsistencies in reporting – Subjectivity – Inaccuracies in retrospective description of events

9 Limitations of Level Crossing Incident Analysis Pitfalls of causal analysis on sparse data 1 – Over-interpretation – Tendency for analysts to identify causal factors representative of a category of failure rather than identifying characteristics that may distinguish it – Current near-miss reporting does not describe the “less visible influences” that may condition an incident 1 Johnson, C.

14 R2.119 Benefits for Australian Rail Industry Inform improvements to existing paper-based reporting – Better criteria and sub-categorization consistent with statutory reporting requirements – Simulator-based training for drivers to improve objectivity of reporting Improve understanding of the context of near-misses and causal factors that lead to incidents at railway level crossings – Inform countermeasures – Improve risk models used to prioritize upgrade funding Enhance the understanding of the inter-relationship between human performance and other elements of the system The Future…

15 R2.119 Platform Verticalization R2.119 project focused on near- misses at level crossings Platform can be verticalized to support several application domains
