A Novel Routing Based Path Planning Using RSU and OBU for Time Critical Information Sharing

Dr. Raafiya Gulmeher | Javeriya Shabnam

Abstract: Real-time traffic information can efficiently reflect the traffic condition in urban scenarios. However, how to design an efficient real-time information sharing mechanism to achieve the real-time traveling time estimation and dynamic path planning still remains a challenging problem. In this paper, we first propose an effective real-time traffic information sharing mechanism based on a distributed transportation system with RSUs, which has lower computing complexity and less redundancy. Then, considering current traffic information, we present a method to estimate the traveling time from a source to a destination in the road network, called TTE, which acts as a metric for path planning. Furthermore, we propose a real time path planning algorithm based on TTE comparison via information collection to avoid traffic congestion. We verify the complexity and redundancy of our proposed real-time information sharing mechanism via C#. Moreover, we perform extensive simulations in Vanet MobiSim to evaluate the proposed real time path planning algorithm, which uses the real world traffic scenario and urban map of Songjiang district in Shanghai. The results show that our proposed algorithm outperforms the static path planning algorithm.
