Choosing a method in setting goals for various trips, especially educational trips, is of paramount importance. Nowadays, online taxis have become a relatively new method used by students for educational trips. On the other hand, the traffic restriction zone has imposed movement restrictions on personal vehicles, affecting educational trips within this zone. The objective of this study is to investigate the rate of usage of online taxis in educational trips conducted within the traffic restriction zone. To achieve the study objective, a questionnaire was designed and distributed in Tehran city. After collecting data, 413 responses were received. Initially, descriptive analysis was performed on the socio-economic information of individuals, followed by factor analysis on the factors under study in this research. Furthermore, the ordered logit model was utilized to examine the rate of usage of online taxis by individuals and important variables in educational trips within the traffic restriction zone. Perceived benefits and motivators of online taxis have a positive impact on the attractiveness of online taxis, while perceived barriers have a negative effect. Additionally, females are more inclined than males to use online taxis for this type of trip, and singles also use online taxis. Moreover, individuals residing within the traffic restriction zone tend to use online taxis for educational trips within the traffic restriction zone. By identifying effective and inhibitory factors in the usage of online taxis, this study provides necessary policies and suggestions for online taxi companies and transportation policymakers.

Considering the high human casualties and financial and social costs caused by accidents, one of the important national concerns is trying to reduce traffic accidents; Considering that in all official statistics, human errors are known as the most effective factor in creating this problem; By modifying the traffic behavior of drivers, we can have a significant impact on reducing accidents and casualties. This issue is not possible unless the first brick is laid and before obtaining the certificate, the basic training and then the tests to measure knowledge and skills are done competently.n this research, using the documentary method, we have done a comparative study using the pattern of differences, education and test indicators of countries such as Switzerland, Japan, Sweden, Australia and England, which have had significant success in reducing casualties caused by accidents.In this research, we found that in successful countries, with dynamic training and effective skills recognition tests, through simulators and risk perception tests, as well as checking people's records and giving importance to first aid training, they have had great success in improving traffic behavior.Therefore, it is suggested that in iran, to increase the skills of drivers in facing dangerous situations, the use of simulators should be put on the agenda in training and testing. Also, the requirement of theoretical training before obtaining a certificate or training for technical issues of professional certificates and checking the records of committing violent acts, as well as the importance of first aid training, are effective

value of 0.875, value and credibility with a value of 0.866, participation with a value of 0.864 and persistence with a value of 0.772 are more than 0.5, which was significant at the 0.95 level.

accident experts need acquire specialized knowledge regarding issues related traffic accidents, which requires a suitable range educational standards with the priority variety in programs, new scientific developments, technical knowledge and students' interests The content of textbooks should be changed according specialized and strategic needs.

Today, fuel consumption control is one of the main concerns of managers. The current research aims to investigate the effect of fuel price increase on the type of urban trips using the QRUET model, which is related to the choice of means of travel, in Mashhad and Semnan cities.

In this research, the rapid estimation and estimation of intra-city trips (QRUET) model was used in order to investigate the effect of fuel price increase on transportation. The approach of this research is based on quantitative analysis and descriptive and analytical methods are used together. The research data has been collected from 350 citizens of Semnan through face-to-face visits and in the form of 5 questions.

The results of using this model in Mashhad and Semnan cities in 2017 and after the increase in fuel prices showed that the share of public transportation compared to private transportation increases (1.25-5.54%) and in 1402 Compared to 2017, the share of public transportation is decreasing compared to private transportation (0.82-4.98%).

The findings of the research show that at the beginning of the fuel price increase, urban transportation suffered a sudden shock and the share of using public transportation increased, but after 5 years with the increase in population, income and expenses. it will decrease even more compared to 2017. Finally, it can be concluded that the increase in fuel prices alone cannot significantly increase the share of public transportation in cities.

The validity of the questionnaires was confirmed by respected professors and its reliability was obtained using Cronbach's alpha formula as 0.84 and 0.82 respectively. SPSS software and Kolmogorov-Smirnov test, correlation coefficient, multivariate regression and Friedman test were used for inferential analysis of data obtained from measurement tools.

The findings show that the role of bicycle culture in improving the urban traffic situation has a positive and significant role. Also, the components of the role of bicycle use, including (the existence of a correct culture of bicycle use, a special bicycle route, the suitability of urban streets and thoroughfares), have a positive and significant role in improving the urban traffic situation.
