Proxy-CPM: A collaborative high definition map update for autonomous and connected vehicles

Autonomous cooperative driving systems enable the safe operation of autonomous vehicles. However, the effectiveness of these systems is hindered by the challenge of promptly accessing necessary traffic data. High-definition (HD) maps serve as an extra sensor, providing advance information to autonomous vehicles about changes in the traffic surroundings. Therefore, it is crucial to keep the HD maps up to date. Our solution involves a service that notifies vehicles about updates in the traffic environment, aiming to minimize hazardous situations.
