Australian Level Crossing Assessment Model (ALCAM)
The Australian Level Crossing Assessment Model, often referred to simply as ALCAM, is a risk model for personal injury risk at railway level crossings.
Personal injury risk means that the model calculates and rates the risk of physical injury or death in accidental level crossing collisions. There are other consequences of these collisions which are not considered in the model, such as the cost of damaged rolling stock (trains) and motor vehicles, destruction of freight and delays caused to the transport system. There is also the very real and long term mental trauma suffered by survivors witnessing or being involved in collisions, in particular train drivers. The use of personal physical injuries and deaths as the measure of risk in ALCAM is in common with other similar risk models used in transport. It is a measurable quantity and therefore able to be calibrated and checked against data recorded against incidents.
ALCAM is an official Australian Government risk modeling system commissioned in 2003 by commonwealth heads of government in response to a spate of fatal level crossing crashes. It was created as a uniform national system to address the need for a more objective way of prioritising and treating the highest risk crossings than reacting to incidents or political lobbying.
It is used by government transport agencies, railways and road agencies such as highways departments and local government to assess, rate and rank the highest priority (highest risk) crossings for such things as active control upgrade programs and use in formal risk assessments. It is applied in all Australian States and Territories having rail systems, as well as New Zealand.
There are two ALCAM models, one for road crossings and the other for pedestrian crossings. They both have similar structures but deal with the different operating conditions and motivations of road vehicle drivers and pedestrians which cause risk.
ALCAM can not model or predict the likelihood of deliberate deaths at level crossings and is not suitable for that purpose.
