Regarding the increasing intra-city trips and congestion on the streets and highways, governments are thinking of introducing a new transportation system or improving existing systems. To reduce the negative impacts of transportation as well as increasing reliability, the development of sustainable rail transport systems has been the focus of many developed and developing countries. The initial investment and high operating costs of rail systems are a major financial challenge for transport organizations, and it is essential to identify travelers' behavior and preference before introducing the new system. This study aims to model the modal shift to light rail transit (LRT) in the case of educational trips and identify the effective factors. In this Regard, a stated preference questionnaire consist of four parts icluding travel characteristics, attitude characteristics, number of modes used per week and individual characteristics was designed and 407 students were interviewed as the sample size at Tarbiat Modarres University on May 2018. Estimated coefficients of eight binary logit models indicate that there are several factors with different level of sifnificance in exolaining the modal shift from existing travel modes to LRT. Major finding shows, a 20% reduction in fare, a 50% reduction in seating time, and a 20% reduction in LRT travel time compared to the last individual mode used have the most impact on increasing utility and modal shift to LRT, respectively. Results are applicable to facilitate policymakers' decision-making and planning in future transportation systems and determining appropriate policies to increase LRT's utility.

The purpose of this study was to investigate the effect of mobile software on the effectiveness of traffic police and prevent drivers from committing violations in the city of Hamadan.

The present study is based on the purpose of Nader cover-up and in terms of nature and description-survey method. The statistical population of this study was the statistical population of the present study consisting of all employees of the traffic police of Hamadan city. The number of samples was obtained by simple random method through Cochran's formula 100. Agrawal and Sanders (2003) questionnaire was used to collect data. In this study, data analysis was performed through structural equivalence model and the use of smart PLS software.

The findings are shown, beta for your hypotheses, better communication than time saving 0.379, better communication in the absence of information 0.418, just to save time of use 0.198 Availability of information on police effectiveness 0.412, mere time-saving information on police effectiveness 0.302, availability of information on resale of drivers from promotion to offense 0.377 obtained, and these assumptions have not yet been met.

It was concluded that communication is better due to the use of mobile software and access to information for officers and saving officers' time in preventing drivers from being promoted to violation, also better communication due to the use of Officers' communication and information technology, as well as saving time and access to information for officers, are also effective due to the traffic police.

Traffic police currently use various methods to carry out their inherent missions, including increasing patrol teams and using various equipment. At the same time, it still faces various problems in performing its duties. Therefore, in order to better implement the regulations and the citizens' satisfaction with the performance of the police, it needs to review its working methods and performance. By deploying police car patrols in appropriate places and managing the city's traffic by using surveillance cameras, in the event of traffic disruptions such as vehicle breakdowns or traffic accidents, etc., car patrols can be reduced to a minimum. Possible time to fix the problem.

The research method is descriptive-analytical. To analyze the data, spatial statistics analysis and statistical-graphical methods in the form of GIS have been used. AHP method and Expert Choice software have been used to prioritize the criteria and sub-criteria for locating vehicle patrols.

The results showed that the accident criterion is the most important and the topographic criterion is the least important among other criteria. Also, the fatal accident sub-criterion with a weight of 0.386 had the highest weight and the distance sub-criterion from residential areas had the lowest weight compared to other sub-criteria.

By describing the current situation of police car patrols and identifying its shortcomings, the effective variables in the location of police car patrols were identified and prioritized. Also, how to position correctly based on priorities was obtained.

This study investigates the effect of compiling master's theses on improving the educational, research, professional and personal skills of graduates of the last five years in the faculty. The research method is descriptive-analytical with library studies and obtaining the opinions of faculty members. The statistical population of the study included 75 graduates of Master of Traffic Management who were selected in full. The method of collecting field information and its tools are a researcher-made questionnaire that contains 43 closed questions with Likert scale and the information was collected through an online online questionnaire. The validity of the questionnaire was done through content method and questions from 12 professors and experts and its reliability was obtained through Cronbach's alpha coefficient (0.88). Data analysis was performed using Excel and SPSS statistical software. In order to answer the main hypothesis, and to enrich the research, inferential methods such as t-test have been used. The use of t-test requires the normality of variables. Kolmogorov-Smirnov test was used for this purpose. The results show that all four hypotheses about increasing educational, research, job and personal skills have been confirmed, so it can be concluded that the development of a master's thesis has improved the skills of graduates.

Since 1960 the new movements in the field of urban transportation aimed at promoting pedestrian staging in the city and reducing vehicle dominance, are pedestrian-oriented and policies of making pedestrian street. Pioneering as one of the policies of moving towards the development of cities over the last half century has attracted cities in the world. However, the implementation of walkways in different cities has been accompanied by a variety of results, to the point where some sidewalks have failed and have been opened again on the cavalry. In this research, we attempt to explain and identify the shortcomings and weaknesses of the measures by assessing the pedestrian and cavalry traffic by measuring the valid criteria and indicators with what has been implemented. The research method is descriptive-analytical and based on documentary and field studies. Analysis of the research findings was done using Topsis . Based on the results, it has been determined that the implementation of the policy with a priority index of 0.985 is a better option than turning the street into a pedestrian and prohibiting the passage of a cavalry with a priority index of 0.453 or a one-way passing of the cavalry With a priority index of 0.306. On this basis, it can be said that by achieving a balance between pedestrians and pedestrians and trying to reduce car dependency, a higher satisfaction can be achieved.The results of this article can be used as a guideline for future traffic-based implementation in problematic historical context considering pedestrian satisfaction.

Traffic Police provides a lot of services to citizens, however, despite many advances in various fields, there is still no comprehensive model for measuring the quality of services of this specialized police. The present study aims to analyze the factors affecting the quality of traffic police services with the ISM approach.

In this study, interpretive structural modeling was used. Data were collected from experts who were selected through purposive sampling. After identifying the factors influencing the quality of Traffic police services, it was approved by experts.

The results of interpretive structural modeling showed that among the 11 factors extracted, coherent inter-sectoral relationship, modest behavior during authority, empowerment, application of new technologies in service delivery, transparency in work processes were highly guided and dependent. This means that any change in them affects the whole system.

An appropriate model for the quality of road services with eleven dimensions including application of new technologies in service delivery, soft and hard police empowerment, coherent inter-departmental communication in the police force, speed in service delivery, accuracy in service delivery, modest behavior while authority, Competence and skills of employees, transparency in work processes, reliability, ease of service delivery and work environment conditions.
