The Highway Safety Manual (HSM) is being developed by the Transportation Research Board and AASHTO. Current plans are for AASHTO to publish the 1st Edition HSM in 2010. The latest draft of the HSM (3.1; April 2009) contains four parts (A, B, C and D). Part C documents Crash Prediction Methodologies for three types of highways: rural two-lane highways, multilane rural highways and urban/suburban arterials. The IHSDM 2009 CPM Beta Release is intended to be – to the extent possible – a faithful software implementation of the crash prediction methods documented in Part C of the HSM (Draft 3.1). For more information on the Highway Safety Manual, visit the HSM public website at www.highwaysafetymanual.org.
