Intelligent Transportation Systems (ITS) play a fundamental role in reducing traffic congestion and increasing safety during daily transportation. These systems can also be useful in improving social welfare leading to general satisfaction. Proper performance evaluation can be efficient in improving the performance of these systems, and providing a scientific assessment index system can assist decision-makers in smart communities to plan for the development of ITS. However, the evaluation of these systems requires identifying appropriate indicators of performance evaluation that are consistent with the views of the beneficiaries of these systems. In this paper, performance evaluation indicators of ITS have been identified, and three indicators entitled "environmental and safety", "assistance in reducing traffic congestion" and "attractive public transport" are presented to evaluate the performance of these systems. Moreover, the intelligent transport systems of the Tehran-Karaj Freeway in Iran are studied, and inferential statistical methods are employed to test the research hypotheses. It is worth noticing that in this study, a one-sample T-test method is used for hypotheses assessment and the SPSS software was used to analyze the findings. Also, the results demonstrated that the performance of ITS in the Tehran-Karaj Freeway regarding the indicators, such as "Declaration of route blocking information due to maintenance or reconstruction" and "Declaration of path geometry conditions" has not been acceptable.

Nowadays, due to the quick increase of population, degradation of the environment and social disparity moving towards sustainability is an indispensable issue. Aside from this importance, paying attention to sustainability provides opportunities for firms to be innovative. Previous studies largely focused on identifying drivers that enhance the firm capacity to innovate new products and services. However, less attention has been paid to sustainability orientation as a direct driver of a firm’s innovativeness leading towards long term business performance. In this study, sustainable supply chain drivers, strategic sustainability orientation and firm performance have been evaluated. The mediating concepts such as corporate environmental management and corporate social responsibility impacting the relationship between strategic sustainability orientation and firm performance have been tested too. The results illustrate that employees’ motivation and managerial attitude have positive impacts on strategic sustainability orientation and on the other hand strategic sustainability orientation with the mediating roles of corporate environmental management and corporate social responsibility has a positive effect on firm performance. This study was conducted on 120 Iranian companies that are active in food industries by using the SEM method.

Following the rapid development of the Internet, e-commerce websites are widely used today for various goals. An essential point in the prosperity of these websites is their level of usability. Accordingly, measuring this usability is indispensable for these websites to check whether they are moving in the right path. Thus, in this article, the usability scores of five well-known online food-ordering websites in Iran have been evaluated using a novel fuzzy Kano method with respect to design parameters. In addition to assessing usability scores, the design parameters of these websites have been classified and reviewed in a detailed manner in order to determine the design priorities of these websites as one of the main results of this study. Data were gathered using a questionnaire with 190 respondents. Results demonstrated that Snappfood is the best online food-ordering website in Iran. In addition, sorting restaurants based on customer satisfaction score, using high-quality images of foods along with the image zooming feature, and the existence of complete information about foods and restaurants are the most effective and important design parameters of these types of websites according to the findings of this study.
