This paper describes a design of the WAVE antenna system in V2X wireless communication systems for Intelligent Transport Systems. The WAVE standard protocols defined 5.825~5.9GHz frequency range for wireless communications with V2X. In a recent, A study of WAVE communication system it has been studied mainly the base station and the OBU technology in order to improve the communication performance of the communication distance. In this paper, the proposed vehicular WAVE antenna using the EBG structure is to improve performance. The proposed WAVE antenna with EBG shows improvement of return loss and radiation beam pattern. The performance of WAVE communication systems for intelligent transport systems is dependent on the performance of antenna. The proposed vehicular antenna for WAVE communication systems shows improvement of return loss for performance.

Cognitive Radio (CR) technology is proposed for using the unused spectrum band efficiently because of the spectrum scarcity problems. Spectrum sensing technology is one of the key challenge issues in cognitive radio technologies, which enables unlicensed users to identify and utilize vacant spectrum resource allocated to primary users. In this paper, the cooperative spectrum sensing technologies apply the ITS(Intelligent Transport System) and performance of signal detection analyzes. Then, we utilize the OR-rule and AND-rule for the cooperative signal detection. These data fusion rules improve the performance and reliability of the signal detection.

Intelligent Transport Systems(ITS) has been currently growing attention in industry as hightech traffic system and ITS infrastructure has been built not only on expressway but also on national highways. Although the effect of ITS installation on national highways is not easy to measure with quantitative methodology, it is necessary to develop the quantitative method to verify the effect accurate analysis of ITS effect. In this study, the analysis of cost efficiency of ITS project carried out by Iksan Regional Constriction Management Administration(IRCMA) was conducted. Analysis period and discount rate were assumed as 10 years and 5.5%, respectively. Several measures of the effect including reduction of travel time, CO2 discharged and fuel and the value of Variable Message Sign(VMS) information were proposed. Concludingly, ITS project implemented by IRCMA appeared to be cost effective, indicating 1.20 of B/C ratio, 12.4% of IRR and W1.48 billion of NPV.
