Abstract

This paper analyzed several road factors that affect crash occurrence that happen in Indonesia Toll roads. The factors analyzed are Annual Average Daily Traffic (AADT), road length, presence of rest area, and number of lanes. The purpose of this paper is to determine if these four factors affect the crash occurrence at Indonesia toll roads. The method that is used in this paper is negative binomial regression. The data collected are separated based on the number of lanes and also toll road segments. The data were obtained from PT.Jasa Marga for 4 years period (2012 - 2016). In this study, there are two types of model, first one is 'basic' model where AADT and road length are the only explanatory variables that processed and for the second model is the 'improved' model, where in this model, some explanatory variables are added, and some of the outliers are removed.
