Modeling of the Effect of Toll Road Characteristics on Accident Rate

A traffic accident is an event on the road that is unexpected and unintentional.Traffic accidents have an impact on the national economy as evidenced by the contribution of traffic accidents to economic losses in the form of a decrease in GDP by 2.9% -3.1% or equivalent to USD 1.332 Billion -USD 1.465 Billion.So, to minimize accidents, an analysis is needed that is useful for anticipating accidents.This study intends to obtain the effect of the characteristics of intercity toll roads, as well as urban toll roads, on the accident rate.The stages conducted in this research are previous research studies, data collection, determining variables, and modeling.Based on the analysis that has been done in this study, a negative binomial distribution is used to determine the accident rate of inter-city toll roads and the Poisson distribution to determine the accident rate of toll roads within the city and the fatality rate of toll roads between cities and within cities.There are nine parameters used in this model, which can cover more things than similar studies that have been done before.
