This research was conducted to investigate the effect of using intelligent transport information systems in traffic management. The method of research is analytical-descriptive method and in terms of aim it is in the field of applied research. In this research, library study methods and field methods such as a questionnaire were used for data collection. Validity of the questionnaire, which was based on indicators of the Pepark World Assembly for intelligent transportation systems components and based on the indicators of the Ministry of the interior for traffic management components, was confirmed by professor of research, Dr. Abdullah Hindiani. Reliability of the questionnaire was 0.83 with Cronbach's alpha. The statistical population of the research consisted of all Tehran drivers in region 1 of area 2, which was considered unlimited due to its wide extent. its sample size was 384 by Cochran method. SPSS and Excel software were used to analyze the data. Data analysis revealed that there is an weak and independent relationship between each of the independent components of intelligent transport systems with the components of traffic management. But the sum of the relationships of the independent variables with dependent variables has a strong relationship that confirms the main hypothesis of the research (the effect of intelligent transportation systems on traffic management). Also, the results of this study showed that at the present time intelligent transportation systems are not much used in the routes, but if used properly and extensively, these systems can be used as a convenient and efficient tool for traffic management.

To elucidate the phenomenon of reckless driving behavior, there are many factors, including cultural, social, political and economic ones. Nonetheless, reckless driving behavior can be linked to other sociological concepts such as social values and social norms, social comparison of life styles between the upper and lower classes, success in life, deviant behaviors and reference group orienting the behavior. This paper identifies the causes of high-risk driving behaviors using step-by-step methodology in diagnostic analysis and explains the contribution of factors (independent variables) in the distinctive power among the triad elements of the tendency towards risky driving behavior (dependent variable) and it explain and examin hypotheses on some related factors employing a survey method based on the related theoretical framework. In this paper, all young boys in the city of Sari were included in the statistical population. The volume of research sample size after the distribution of the preliminary questionnaire and the exact estimation of the variance of variables was determined 200 pepole. All items used have acceptable and desirable load factors and indicated the indicators of goodness of fit of the model. Based on the diagnostic analysis method used for analysing the data collected, the findings indicated that the three variables "social comparison", "rationality" and "selfregulation" had the largest shares in the focal differential equations, and according to the structural matrix, the linear correlation was stronger among the three independent variables and the diagnostic functions

Traffic accidents and casualties caused by it are one of the current challenges of human societies, which impose many economic costs on countries. Determining the risk of accidents in the network of roads can be one of the basic steps for assessing the safety of the network and identifying full of accident parts. The most important damage caused by accidents is the death casualties. Therefore, determining the risk of accidents based on the risk of casualties is an effective way to focus on the most critical parts of the roads network. The purpose of this study is to determine the criteria for accepting the risk of casualties in out of town highways. The risk of casualties was also determined by the number of deaths, the annual average daily traffic volume, the length of time examined and the average number of occupants of vehicles. Accordingly, the rate of death of the out of town highways was determined by the three reference societies and then compared with the criteria of quality-rate control method, average kill rate, mean plus standard deviation of deaths rate and twice the death rate and were identified full of accident parts. Comparison of the results of the criteria showed that the average criterion, as well as the standard deviation of the rate of deaths due to executive and credit constraints and the necessity of addressing the most critical parts, is a more appropriate criterion for the current state of the country's roads.

Increasing the number of vehicles and intra-urban and outbound trips has led to an excessive increase in the negative costs of transportation systems. One of the most important of these is the issue of driving accidents. Occurrence of driving accidents is inevitable, However, such incidents in our country have so far increased that today, most of the claims in courts are claimed for damages and litigation relating to accidents caused by vehicles and such incidents are the most important and common type of pseudo-crime that at least in the last half century has been allocated for most of the cases of the judicial authorities. On the other hand, responsibility is one of the most fundamental legal facilities that has been raised in Iran's criminal and civil law in the form of compensation and tolerance of punishment. The institution of its responsibility is divided into two parts: criminal and civil. The fault is a crossroads of criminal and civil liability in driving accidents. The results of this research carried out by the library method show that The exact examination of the fault theory, recognizing the responsible person for the payment of damages, the determination of a third party and the means of differentiating it with the vehicle owner, are necessary in the investigation of the crimes caused by driving accidents

Human factors are one of the three main causes of road accidents. Psychological nerve indicators such as reaction speed and pay attention mode may affect driving performance. The research project was a systematic review. With keywords related to driving behavior and road accidents were searched from databases and finally, 22 articles were selected for systematic review. A system was arranged for rating the quality of articles and the level of homogeneity of the results was considered based on the tree chart. Most driving psychological nerve sciences have been conducted on the elderly or people with neurological defects such as multiple sclerosis, stroke or head injury. The best predictors of driving accidents are tests related to visual observation and executive functions. Tests on the use of visual space and the tracking test and visualization test are the most commonly used psychological nerve tests in the field of driving. There is a positive and stable relationship between basic cognitive functions and driving errors in elderly people. Assessing drivers with psychological nerve tests and designing rehabilitation courses for infinite violent drivers by restoring or strengthening the functions of the psychological nerve may be effective in reducing road accidents and modifying driver's behavior

The purpose of this study was to investigate the role of Zabol 120-day storms on
the number of road accidents of axes leading to Zabol city in Sistan and
Baluchestan province. The research method is the documentary research and the
use of secondary data of the synoptic station of Zahedan and Zabol during the
years 2010-2010. Initially, the amount and intensity of speed data of the element
of wind and horizontal vision were obtained in a 5-year time frame. Using Excel
software, wind data with a speed of more than 10 nats / s and a horizontal view
of less than 1000 m, as well as the number of accidents occurring, were obtained
from the Police Station in Sistan and Baluchestan province and were analyzed
statistically. The results showed that the highest number of road accidents in
Zabol city occurred during the summer and during the 120-day storms. By
recognizing the features and anticipating this type of weather disaster one day
ago, while managing effective and road safety and informing to road assistance
bases, emergency, road police and alerting to drivers can reduce the damages to
this climat disaster
