It can have positive effects on police performance.In this research, a descriptive survey method has been used. The statistical population of this research is all the managers and employees of East Tehran Police Command in the number of 555 people who were randomly selected using the Cochran 145 formula. Considering the nature of the subject, a researcher-made questionnaire was used to measure the research variables, and its validity was calculated using the content method and its reliability was calculated using Cronbach's alpha 0.87. For data analysis, descriptive and inferential statistics indicators such as; Average, Kalmograf-Smirnov test, Chi-square test and Friedman test were used.The findings showed that the methods of preventing the theft of vehicles based on increasing the effort required to commit the crime, etc., were recognized as the most important methods of preventing the situation.Therefore, since the mentioned methods cause actual crime prevention, planning and educational designs of families by the institutions in charge, correct urban designs and more coherence to police control measures with Equipping manpower and sufficient facilities for crimeSituational prevention is one of the necessary ways to prevent crime and it causes the deactivation of crime hotspots.

considering the role and importance of vehicles in people's lives, if the theft is not curbed and not discovered, it can have negative effects on citizens' dissatisfaction with the performance of the police, since a number of stolen vehicles are not discovered and many are due to interactions. performed on their basic elements become a grade document and on the other hand, due to the lack of expertise and precision among the explorers, a large part of the vehicles are placed in roofless parking lots for a long time, which suffer from major problems in their appearance, decay and parts are lost; Also, not having accurate statistics and information about confiscated vehicles has caused the necessary planning to determine their tasks.

This research seeks to answer the question of whether the authenticity indicators of the basic elements of the car are effective in discovering stolen cars? The hypothesis of the research is that "there is a significant relationship between knowing the index of matching the technical specifications of the car with the original documents and the discovery of stolen cars. To check the correctness or incorrectness of the research, a questionnaire with (4 open questions and 16 closed questions) was distributed among the statistical community.

After collecting and analyzing the results, it was found that these measures are effective in detecting stolen cars with a high percentage. The current research is a descriptive-analytical applied survey of the field method or field research (survey).

The study examines the selection of color (car and road) to modify driving behavior of traffic users with the aim of providing executive strategies for changing traffic behavior of users. The author believes that it can be achieved using cultural approaches and attention to the color factor in the car and the road or behavior change to improve the traffic behavior and reduce the driving accidents. For this purpose, the researcher used a survey method to collect data. In this method, experts' opinions can be used to evaluate the indicators of traffic behavior change. By this description, the method of this research is a survey and  practical in terms of purpose and. The statistical population of this research has been the experts and elites of traffic management areas. The data collection tool was also maed by a researcher-made questionnaire that its validity and reliability were confirmed before the implementation. Data was also analyzed using Pearson's test. The results of the research show that, all of the hypotheses are meaningful In Pearson’s test and it can be stated that are correlated between the type of color application in terms of the optical spectrum – the role of car color in the control of the emotions - the role of road color and proper alignment - the role of color in reducing the fatigue and proper driving - the color of the color in setting aggression patterns in driving and the role of advertising and informative colors and reducing driving errors in the four bases of landslides- Intentional violations - unintentional violations and reduction of driving errors.

The phenomenon of theft as a criminal offense is one of the major problems of human societies. Police have always been looking for a way to identify effective measures in the field of theft prevention in the field of structural and mission, and to offer an effective solution for eliminating or reducing this offense. Police stations are one of the police stations that can be effective in preventing theft, in particular car theft. Therefore, the present study aims to investigate the role of police stations in preventing vehicle theft in the southwestern region of Tehran.
The present study is applied in terms of purpose and nature, and as a method of implementation, it is a survey and descriptive-analytic. To collect data, field method and researcher-made questionnaire were used. The statistical population included 141 staff members in the south west of Tehran city. The face validity method was used to assess the validity of the items, and the reliability of the questionnaire was assessed by Cronbach's alpha.
Findings and Findings and results of the research show that the location of police stations, correct management, organizational talent and organizational equipment of these stations are all effective in preventing vehicle theft. Based on the research carried out and the experiences of law enforcement activities conducted by researchers over the past years, one can conclude that, in proportion to the breadth and depth of interactions and exchanges between the police and the community, crimes can be effectively prevented at the community level.

public participation and ways to attract people in the prevention of crime and particularly crimes of theft, has been considered by scholars and social scientists. Today, most criminal regimes seek to use non-criminal procedures and preventive policies and programs, to eliminate areas of crime in the community, This paper aims to identify The ways of to achieve public participant attraction in preventing auto theft in Yazd province And seeks to answer the question, what ways attract public participation in preventing people from stealing the car?

Nowadays role of vehicles in environmental pollution and energy consumption is very important issue in level of world society. Researchers have striving hard for improving of vehicle function by new methods and technologies respective to the pollution and fuel consumption. During previous years against fuel crisis and increasing the cost and also environmental pollutions, vehicle manufactures have trying to economize the vehicles by using new technologies in order to decreasing fuel consumption and saving environment. Pollution crisis which is caused by vehicles is propounded as a big problem for both developing countries and advanced countries which are exposed them to environmental big dangers. The environmental problems, deficiency of fuel and energy are leading to request of increasing energy consumption efficiency, decreasing environmental pollutions, increasing global competition between vehicles industry companies, proportion the grade of society equipment for decreasing of acoustical and environmental pollution and yet general tendency for using safe vehicles with low fuel consumption cause to encourage vehicle manufacturer to develop the modern technologies to secure the requirements. For this reason in this article, present modern technologies in vehicles manufacturing for compatibility with environmental conditions. Environmentally friendly vehicles have low air pollution, low acoustical pollution and recyclable and this technologies are consist of fuels and materials ecofriendly.
