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

Abstract

A methodology has been previously developed to provide the required data for the iRAP Star Rating 7 model using data sourced from MRWA database information (corporate inventory) and road 8 condition information supplemented by other data sources. This is referred to as MRWA RAP to 9 distinguish from data collected in accordance with iRAP protocols which provides data for AusRAP. 10 The iRAP data is used by the Australian National Risk Assessment Model (ANRAM). This paper 11 describes the work done on updating MRWA RAP as well as the application of the ANRAM model 12 to assess proposed treatments on the Great Eastern Highway to improve road safety.
