本系統透過車載短距通訊(WAVE/DSRC)技術輔以雷達掃描十字路口周遭車流環境及行進中車輛即時動態GPS位置取得當下經緯度，車速，方向等資訊並將其廣播給周遭駕駛以供駛入該十字路口區域的車輛獲得精確的橫向來車即時警示資訊，使縱向車道的車輛大幅提升行車安全。最後根據實車展示結果，該系統能有效率且精準地通知駕駛人，同時過濾掉不必要的假警報警示，進而改善整體用路人安全及品質。

In the proposed systems, it is applied by the technology of Wireless Access in Vehicular Environment/Dedicated Short Range Communication (WAVE/DSRC) combining radars installed against the intersection scanning the surroundings and Global Positioning System (GPS) of vehicles to access vehicular speed, latitude, longitude, direction, and other information immediately. The above information will be gathered into DSRC On-Board Equipment (OBE) of the vehicle around the intersection. Meanwhile, it will provide real-time transverse alerts to the vehicles. In this paper, based on theoretical analysis and field trial, it is revealed that the propose d system can warn the driver efficiency, improve traffic safety, and avoid unnecessary false alarms.
