Connected Vehicle Technology (CVT) is a great step in evolution of Intelligent Transportation Systems (ITS). In this technology، some equipments installed in vehicles and road sides exchange critical vehicle data such as position، speed، and direction of movement in a given range with each other، so that the drivers will gain a situational awareness in their vicinity and will be able to make appropriate real-time decisions in an effective manner. In addition to safety and vital applications، this technology can help mobility and reduce traffic congestion. Furthermore، having access to adequate information، the drivers can choose better routes، improve their driving behaviors، and make their trip more fuel-efficient and eco-friendly. This study introduces connected vehicle technology concepts and surveys the relevant applications including safety، mobility، environmental issues etc.

Connected Vehicle Technology promises a great revolution in the modern transportation systems. By combining wireless communication technologies and the potential of information technology، an intelligent vehicle is embodied that can serve as a powerful assistant for the driver in avoiding hazardous situations and offering him an eco-friendly driving style. This paper investigates some of the most important research and development activities in the field of connected vehicle technologies around the world. After a brief review of the current research and development efforts in some of the world countries، the most important programs and pilot projects in those countries are investigated briefly. At the end some concluding remarks are extracted from the overall discussion.

The Connected Vehicle Technology project involves various stakeholders. Since every stakeholder has various concerns and requirements and may have a different idea about the project، we need a variety of motivational methods to involve them effectively. Hence identifying and classifying the project stakeholders properly in the very first step and then analyzing the stakeholders and their motivational methods according to their requirements and capabilities، is a significant task. In the most of the time، identifying all the different groups of stakeholders is difficult while we can have access to some samples of them. In this case we need to make sure that these samples of stakeholders are good representatives of them and will lead us to the key clusters. Therefore in order to identify and classify the stakeholders we''ve made use of their samples in this paper. Experts have mentioned some of the project''s stakeholders and their properties، then the stakeholders and their descriptions have been provided using the deductive methods. In order to classify the mentioned samples k-means approach has been used. Parallel to this quantitative approach، value chain analysis has also been employed for identifying and classifying stakeholders so that the accuracy of clustering could be evaluated and compared using value chain analysis method.

Deploying Connected Vehicle Technology (CVT) will improve the drivers'' total awareness of their surroundings. It can also improve the quality of travelling through an integrated communication between vehicles and road-side units. For commercializing a new and innovative technology successfully، we require a thorough research on different aspects of technology such as policies، culture، and environment. Identifying and analyzing the stakeholders'' properly in conjunction with the accurate conception of the economic potential of stakeholders in a business frame، has been one of the key success factors of every CVT deployment initiative. After introducing the global initiatives regarding business modeling، some relevant scenarios have been investigated. Additionally a general framework for the business modeling of CVT has been proposed. Besides، for one specific part of the system users including drivers and passengers as the final consumers، a basic model was proposed.

This paper investigates the methodologies of roadmap development for CVT in Iran. Since the knowledge of CVT roadmap development is not integrated, we required a method to collect structure and analyze this unclassified knowledge in order to define the future of CVT. This method has to consider both global trends and national transportation issues and also provides appropriate approaches to improve the specific issues of the country such as road safety.In this paper the common methods of roadmap development for CVT have been explained, following a description of the advantages of applying a roadmap and the identification of the general patterns. A conceptual model has also been proposed for developing the roadmap of the technology. Then various methods have been identified and investigated, and according to some criteria a method has been proposed for the CVT project. In the end S-plan method as the selected method has been described and the features of this method have been explained in details.

Connected Vehicle Technology (CVT) as a new generation of Intelligent Transportation Systems (ITS) is rapidly growing with various pilots in progress. In some countries various applications of this technology has already been implemented. Since this technology is relatively new and each country has its own individual situation، identifying the upcoming challenges and requirements for applying this technology beforehand (i. e. prior to the implementation phase as a nationwide project)، is a critical task that requires special attention. In this study some global initiatives and relevant projects that have been performed in various countries are introduced، afterwards the requirements for implementing this project in Iran have been identified and investigated briefly. Based on the global initiatives performed in 20 countries and more than 50 projects، various challenges، requirements and key approaches for dealing with the relevant issues in 4 main technical، managerial، operational and legal areas have been investigated. According to this study 24 requirements and prerequisites for implementing this project in large-scale and specifically in Iran، have been identified.

Intelligent Transportation Systems (ITS) offer various innovations that can transform transportation systems. According to many experts، the greatest driving force of the ITS evolution will come from the Connected Vehicle Technology (CVT). The effective wireless communications deployed in this technology، has the capability of transforming transportation safety، mobility and also reducing environmental impacts using Vehicle to Vehicle (V2V) and Vehicle to Infrastructure (V2I) communications. Implementing the connected vehicle technology not only provides a futuristic vision for this technology but also transforms the intelligent transportation systems worldwide. The governmental organizations، transportation research centers and car manufacturers are trying to develop this technology and they''ve already achieved some notable achievements. This study investigates the impacts and role of the vehicular communications in intelligent transportation systems.
