汽車行業的未來依賴於車輛的通信能力，而CV2X（蜂窩車聯網）是一個國際車輛通信標準，旨在引領行業向前發展。CV2X由數百家公司推廣，包括汽車製造商、移動運營商、半導體公司、電信供應商和道路運營商。
CV2X是一個相對較新的技術標準，屬於3GPP組織，可以在5.9GHz的智慧交通（ITS）頻譜上運行，包括：
1. 車對車：車輛之間將連接以實現安全和資訊共用。
2. 車對基礎設施：車輛將連接到路邊基礎設施，以獲取安全和自動駕駛支援的資訊。
3. 車對網路：車輛將連接到網路以訪問互聯網。
4. 車對行人：車輛將連接到行人以確保安全。
通過RSU（路邊單元）和4G/5G小型基站，利用蜂窩網路，並與現有基礎設施高度相容，降低了成本並提升了運輸性能。利用5G NR的高速、高可靠性和低延遲，它提供了即時管理、3D地圖和自動駕駛。
智慧交通信號燈適應CV2X並在道路上實現實際應用：
1. 行人衝突警告：
通過AI監控道路環境，當潛在的行人-車輛事故發生時，RSU向OBU（車載單元）設備發出PCW（行人衝突警告）警報，提醒司機注意附近的行人，減少事故風險。
2. 紅燈違章警告：
在車輛可能違章闖紅燈時，基於車輛的速度和與路口的距離，提醒司機即將到來的信號燈路口並提供警報或警告。
3. 公共交通信號優先：
當公共車輛接近路口時，車輛的OBU向RSU發送優先通行請求。RSU根據交通信號狀態調整信號燈，提供如縮短紅燈時間或延長綠燈時間等服務，以便車輛順利通過路口。
4. 施工區警告：
當發生道路施工時，附近的RSU向OBU發出RSWZ（施工區警告）警報，提醒司機注意附近的道路施工並減速。
The automotive industry’s future relies on the communication capabilities of vehicles, and the CV2X is an international communication standard of vehicles to lead the industry forward. CV2X is promoted by hundreds of companies, including automakers, mobile operators, semiconductor companies, telecom suppliers, and road operators.
CV2X is a relatively new technical standard, which belongs to the 3GPP organization and can operate on the 5.9GHz Intelligent Transportation (ITS) spectrum, including:
1. Vehicle to Vehicle: Vehicles will connect to vehicles for safety and information sharing.
2. Vehicle to Infrastructure: Vehicles will connect to roadside infrastructure to get the information for safety and autonomous support.
3. Vehicle to Network: Vehicles will connect to networking to access the internet.
4. Vehicle to Pedestrian: Vehicles will connect to pedestrians for safety.
Working through RSU and 4G/5G small cells, taking advantage of cellular networks and highly compatible with existing infrastructure, reduces the cost and enhances the performance of transportation.
Leveraging high speed, high reliability, and low legacy of 5G NR, it delivers real-time management, 3D maps, and autonomous driving.
The Smart Traffic Light adapts with C-V2X and brings real applications on the road :
1. Pedestrian Conflict Warning:
Through AI CCTV monitoring of road environments, when potential pedestrian-vehicle accidents occur, RSU issues PCW alerts to OBU devices to remind drivers to pay attention to nearby pedestrians, reducing the risk of accidents.
2. Red Light Violation Warning:
Advise drivers of an upcoming signalized intersection and provide an alert or warning when the vehicle may violate a red light, based on their speed and distance to the intersection.
3. Transit Signal Priority:
When public vehicles approach intersections, the OBU of the vehicles sends a priority passage request to the RSU. The RSU adjusts the traffic signals based on the traffic signal status, providing services such as shortening the red light or extending the green light to facilitate smooth passage through the intersection.
4. Work Zone Warning:
When road construction occurs, RSUs nearby issue RSWZ alerts to OBUs to remind drivers to pay attention to nearby road construction and to slow down. |
