Abstract

Traffic accidents are a great concern in traffic safety since they unexpectedly and sometimes unavoidably cause fatal and non-fatal injuries, or material damage. The causes of traffic accidents can vary, but they can always be linked to one of the four basic factors: human, vehicle, road and environment. However, there are some places where traffic accidents happen more frequently than in some other places. The decision-making process about dangerous sections of road using the Multi-criteria decision-making (MCDM) model involves the definition of quantitative and qualitative traffic safety criteria. The model used in the paper consists of five quantitative and two qualitative traffic safety criteria. Based on those criteria the ranking of the prospected sections will be carried out. By analyzing the total number of traffic accidents, by their categories, analyzing the current state of the traffic infrastructure and Annual average daily traffic (AADT), seven traffic safety criteria are defined, which in the first phase of model, will be rated and ranked by their importance. By using the Full Consistency Method (FUCOM), weighted coefficients of the defined criteria will be determined, after what ranking dangerous road sections using Weighted aggregate sum product assessment method (WASPAS) is done. The obtained results show which of the offered alternatives is best ranked, that actually shows which section of the road is the safest one.

Highlights

Decision-making is one of the most important aspects of shaping the future of traffic safety, especially in situations where human lives and material goods are endangered, as in the case of traffic accidents
The multicriteria decision-making methods can be used as an adequate tool for making valid decisions when it comes to traffic safety
1.35 million people die each year as a result of road traffic accidents

Summary

Introduction

Decision-making is one of the most important aspects of shaping the future of traffic safety, especially in situations where human lives and material goods are endangered, as in the case of traffic accidents. The multi-criteria decision-making (MCDM) methods are gaining importance as potential tools for analyzing and solving. The multicriteria decision-making methods can be used as an adequate tool for making valid decisions when it comes to traffic safety. 1.35 million people die each year as a result of road traffic accidents. Variations in death rates observed across regions and countries correspond to differences in the types of road users most affected. Based on WHO data (2018), estimated road traffic death rate in Bosnia and Herzegovina is 17.7 (per 100 000 population)
