Abstract:
The field and purpose

By considering different variables that cause accidents, we can refer to unauthorized speed and driving offenses which are as one of the most important factors in accidents. There are relatively good studies around the world to model the relationship between different variables and the probability of accidents.. but so far, a few studies have been done on the impact of three independent variables (the number of traffic violations, transportations and unauthorized speed) on the number of accidents. Therefore,this study aims to predict the number of accidents according to the collected information in previous researches.

Method

This research is a descriptive-analytical study, which was considered as the axis of study of Tabriz-Keshwin axis which is based on field research and documentation reviews. Based on the statistics of crashes on the freeway, the research hypotheses were analyzed using SPSS software. Considering that the collected data is small and the research is to investigate and determine the relationship between the variables, Pearson correlation coefficient has been used to measure the relationship. Also, with regard to the acceptance of the linear relationship between research variables, linear regression has been used to find the relation equation.

Findings

Information related to number of traffic violations, transportations were collecting and evaluating in consecutive years. After calculating it was realized that 31 percent of the dependent variables changes’ was related to independent variables mentioned above. Other changes were related to variables which were not considered in the study.

Suggestions

 It is suggested to be issued to reduce violations related to speed with the field of software launching for the issuance and distribution of a fine or online SMS for offenders who are unauthorized speed, so that violations and accidents will continue to decline.
