—In current road safety practices, the identification
of hazardous road sections are normally based on crash data.
However, the information provided by crash data may not be
adequate to explain the causal factors that lead to a crash.
Therefore, a different kind of road safety indicator that can
extensively describe the actual road environment problems of a
road section is considered essential. This paper considered
fourteen road environment indicators based on their abilities to
portray current road environment conditions and their
potential towards road crash incidence. These indicators were
collected using naturalistic driving technique within the 80-km
road length connecting Kuantan and Maran town in the state of
Pahang, Malaysia in which the composite road environment
risk index was finally developed. This composite road
environment risk index is found to be a useful proactive method
to identify the potential problematic road sections that require
urgent road improvement works as compared to the reactive
crash data analysis method.
