博士 === 國立交通大學 === 資訊科學與工程研究所 === 97 === Since the idea of Intelligent Transportation Systems (ITS) has shown the world its great potential to improve the quality and efficiency of transportation, intelligent transportation technologies have gained the attention from the industry and the academia. Nowadays, the research field of ITS is very popular and it’s believed that the importance of ITS will keep growing up in the future. The goal of ITS is to apply information and communications technologies to transportation infrastructures and vehicles for improving vehicle/pedestrian safety, increasing transport efficiency, and offering in-vehicle entertainment, such as collision warning, driving guidance, electronic toll collection, digital video broadcasting, Internet access, and so on. The practical usages of these applications in our daily lives have shown us their usefulness and also given us the confidence on the viability of this kind of applications that will be applied in the future. Certainly, any application must undergo some tests before it is deployed for service. For a vehicular application, conducting field trials in real vehicular environments is usually necessary. However, these trials are sometimes costly, hard-to-control (unrepeatable), dangerous, and even infeasible when many vehicles and people are required to involve in the trials. In this case, using simulation tools before conducting field trials or even to replace field trials is a feasible alternative to alleviate or eliminate the above problems. This dissertation presents a network and traffic simulator that is useful for wireless vehicular communication network research. This simulator integrates the simulation capabilities of network communication protocols (e.g., TCP/IP, UDP/IP, IEEE 802.16e, IEEE 802.11p, etc.) and vehicular movement behaviors (e.g., moving on road networks, obeying traffic light signals, car following, lane changing, etc.). The design, implementation, validation, and performance of this simulator are presented in this dissertation.
