The strategy is conservative (max-min) and its main emphasis is on the optimal use of existing public transportation facilities in the city

The police are responsible for the enforcement of driving laws and, therefore, their performance has an impact on driving offenses, but this relationship has been underestimated. The present research has tried to investigate driving violation among drivers of Yasuj city and its relation with police performance in their view. The research method is survey method. The statistical population includes all people over 18 years of age in Yasuj who have a driver's license and own a private car. A total of 389 people were selected as sample and selected by multi-stage random sampling. The research tool is a questionnaire. To determine the reliability of its scale, the validity of the construct was used based on a factor analysis and content validity, and to determine its reliability, the alpha coefficient of Cronbach and the re-test were used. The results of this study showed that driver violation is high. Police performance was also found to affect driving violations, and the amount of driving violations decreases as police performance increases in terms of legitimate and respectful behavior with drivers.

The purpose of this study was to find out the difference of the performance of Tehran's drivers in accepting safe time distances among vehicles. The research method was descriptive-survey method. The statistical population was all traffic users (male and female) numbering at 300 people. Traffic users (130 females and 170 females) were selected by using Cochran's formula and cluster random sampling was applied for it. The main research tool was a researcher-made questionnaire that has 15 four-choice questions. And Cronbach's alpha of the questionnaire was obtained at (0.82). Data analysis was performed using U Mann-Whitney method due to the nonparametric data distribution. Research findings at 95 levels showed that there is a significant difference between male and female performance in choosing the longitudinal distance from the front-end vehicle in direct motion, but there is no significant difference between male and female performance in choosing the longitudinal distance with the front-end vehicle for overtaking, when entering the highway, and in determining between lateral and transverse vehicles.

Nowadays, due to the fact that the speed of car ownership growth is higher than the allocation of space to passageways and parking lots, there is always a growing demand for parking. In this research, the main objective of the study is to determine the appropriate locations for constructing floor parking spaces in the 8th district of Karaj. In this regard, after studying the research done in the field of location and determining the scope of the research, the criteria used were determined on the basis of the criteria used in previous research, as well as interviews with experts and elites in the field of transportation and traffic, and by a questionnaire designed to compare paired criteria and based on the hierarchical analysis method, Traffic experts were surveys and by using Expert choice software Criteria, the weight of criteria was estimated. Moreover, by way of Arc GIS software, the initial locations were identified and after performing a paired comparison of these locations, the results were analyzed using the software (EC). Also, after calculating and applying the normal weight of proposed locations in the layers of criteria and aggregation of these layers together, the map of final locations was obtained. The results of this research show that the most important criteria for locating floor parking are as follows: proximity to travel attraction centers, access to main streets, access to public transport, being located in traffic and in heavy traffic streets, location in an appropriate land use, distance from main areas and main intersections, and land ownership fee. The proposed places are as follows: The north side of the Taleghani road, Shahriar Park, Nobovat park, next to Tennis Park, Taleghani Square, Jahanshahr, Madani Square, opposite the Pasargad Shopping Center and opposite the Governor's Office.

Driving without observance of traffic laws and regulations threatens the order and security of any society and disrupts the people of that society. According to the new law on dealing with violations and the increase of 289 percent violations in the year 2016 compared to the year 2010, the need to investigate the effect of speeding up the implementation of the new law enforcement proceedings on reducing the number of accidents and offenses in Tehran is the goal of this study. The purpose of this research is applied and in terms of its method, it is descriptive-survey. The statistical population of this research is the heads of the 26 areas of Tehran's Traffic Police. A researcher-made questionnaire was used to collect data. Findings of the research show that there is a positive and significant impact between accelerating law enforcement and deterrence from accidents and offenses. As a result, it is suggested that the traffic police take a decision in the quick report the violations registered by cameras for filing violations, so-called intangible officers, and double-leaf offenses. Police equipped with day-to-day facilities and technologies to speed up the recording of violations and increasing of the awareness of people and information on important parts of the new law through the mass media and also immediate punishment of violations such as confiscating certificates, social exclusion and vehicle seizure are very effective in reducing violations and accidents

The sharp contradiction between the rapid growth of motor vehicles and the lack of parking spaces, as well as their inadequate distribution in Semnan, have had a profound impact on the quality of life of citizens and the operation of urban roads. The purpose of this study is to evaluate the distribution pattern of existing parking lots and to locate new public parking lots in the city. Data collection is mainly carried out using a library method (text, documents, maps). In order to achieve the research goal, of eight existing parking lots, office centers, commercial centers, tourist places, health centers, educational centers, access to secondary and main passageway streets, the person density per hectare has been used. Also, for analyzing data, we used the standard software and Visual PROMETHEE software, Super Decisions and analytical tools in Arc GIS. Findings and results showed a significant difference between the existing parking lot per capita (0.134) and standard per capita (1.3). The public parking lots in Semnan are not standardized at one level, as the Shahid Rajaee parking lot was rated at 0/222 in the best condition and Tadayon parking was the worst at -0/397 points. Five optimal level of analysis of PROMETHEE was calculated 0.5873, which shows that despite the fact that the four parking spaces of Saadi, Pardis, Shahid Rajai and Public are in better condition than other parking lots, they lack optimal conditions. Are not Finally, for the construction of new parking lots, the land was classified into 5 categories from very suitable to very inappropriate. On very suitable lands, six sites with an approximate area of 16166 square meters, mainly located in inert urban land, were proposed for the construction of a new parking lot.

Considering the industrialization of human societies and consequently the expansion of cities, we are seeing an increase in stressors and, as a result, anxiety and mental illness and depression among different societies; attention to the role of environmental factors as an effective factor in behaviors and actions of humans and the difference between people's ability to control and respond to internal and external stimuli and the impact of these excitements in driving accidents makes it important to study the role of human factors, especially the role of stress and anxiety. Therefore, the use of psychological tests as one of the most important tools for the study of the diagnosis and prevention of stress and anxiety and as a criterion for determining the mental health of people in the community is of great importance. The present article analyzes the data from the questionnaire to investigate the role of stress and anxiety in the driving behavior of male students of the Faculty of Engineering and Technology of Karaj Azad University. This research is a descriptive-survey based on the purpose and the implementation method. The statistical population of this research is 400 male students of technical and engineering faculty of Karaj Azad University in 2015. According to Morgan table, 200 of them were selected by simple random sampling method. The 21 item DASS questionnaire and 28 item GHQ inventory were also considered as a tool to collect information from this research. Based on the results, 77.2% of the subjects in the DASS test had normal-grade stress, 16% had mild and normal stress, and only 4.8% of the students were severely stressed. Regarding the comparison of the two accident and non-accident motorist groups using the general health test for the determination of the health status of the subjects, 78% of the subjects scored less than 23% and 22% of the subjects had scores higher than 23, that is, 22% of the population in the study had a more urgent need for advise services. On the other hand, among factors of anxiety, depression and stress, 63% of stress caused driving. The findings indicate that stress is one of the main factors in accidents and this implies the need to pay more attention to psychological factors that are one of the most important factors in the occurrence of accidents.
