The research is aim at providing services of traffic information and traffic safety in vehicle infrastructure integration of ITS through planning, designing, and implementing the software and hardware, and constructing testing fields. The research is expected to have a static and dynamic traffic guidance application as a service of traffic information, and moreover, the multiple significant applications of service of traffic safety such as providing traffic congestion information, Signal Phase & Timing (SPaT), Road Hazard Warning (RHW), and Intersection Movement Assist (IMA) in the testing field included a highway road and four continuous intersections at a surface road. The research results in accordance with the current traffic management and information service operations will provide a basis of subsequent ITS deployment projects for testing and verification.
