    Abstract: 研究期間:10108~10207;With the techniques of wireless communications growing mature, applications of satellite location service implemented in vehicles are gradually becoming popular. Hence, there are more development and research opportunities among vehicle to vehicle communications and vehicle to infrastructure communications in a heterogeneous vehicular ad hoc network. Intelligent transportation services are then key developing techniques in the world wide. By adopting the characteristics of vehicles running on the road, a number of vehicular safety and inter-vehicle communication mechanisms are invented. However, there are still lacking effective solutions to prevent dangerous driving, drunken driving and tiredness driving. In addition, there are a great number of research issues regarding to improving passenger transportation efficiency, decrease fuel consumption and exhaust gas by adaptively controlling transportation signal system. In a future heterogeneous vehicular ad hoc network, it is inevitable that peoples have to face the issues of information management and network management. Accordingly, issues about how to handle inter-vehicle communications effectively and establish the perfect vehicular network management mechanisms are needed to be solved as soon as possible. The major tasks of this national science council project consist of three years work. In the first year, advanced methods about effectively transferring messages among vehicles is explored and proposed in order to decrease the rate of accidents. The techniques to improve collision avoidance, collision notification and group communication mechanism are major topics. In the second year, the inter-vehicle communication mechanisms achieved in the first year is going to be extended. Advanced Methods including dangerous driving detecting, enabling self-organization management in vehicular group communication is the key study domain. In addition, a dynamic vehicular ad hoc network routing protocol is proposed to support various application services.. In the last year, an energy saving adaptive transportation signal management system is proposed to achieve not only decrease traffic congestion, but also significantly reduce energy consumption and air pollution. Moreover, an advanced heterogeneous vehicular ad hoc network management mechanism is going to be designed and implemented to integrate the traffic management mechanism and network management mechanism based on the achievement of previous two years. Moreover, this system is going to provide a high quality of service by integrate all communications messages of intelligent transportation system to improve the performance of whole system. Last but not least, an intelligent transportation system management mechanism is expected to depict as the template of vehicular safety and traffic control system in future.
