Application of MRWA RAP and ANRAM For Assessing Upgrades on Great Eastern Highway

A methodology has been previously developed to provide the required data for the iRAP Star Rating model using data sourced from corporate inventory and condition information supplemented by other data sources. This is referred to as MRWA RAP to distinguish from data collected in accordance with iRAP protocols which provides data for AusRAP. This same information is used by the Australian National Risk Assessment Model (ANRAM). This paper describes the work done on updating MRWA RAP as well as the application of the ANRAM model to assess proposed treatments on Great Eastern Highway to improve road safety.
