Abstract:

In the real-time path decision method under intelligent transportation system, intelligent platoons may not receive road information, the reason is the failure of road detector or the interruption of communication signal. To solve this problem, the UAV is introduced to work together with the intelligent platoons, which is called the UAV mode. In this mode, according to the driving time displayed in different signals on the lane and the delay time at the intersection, the driving time is calculated dynamically and a path with the least time is obtained. Finally, the results of MATLAB simulation are consistent with the theoretical analysis in four scenarios, which verifies the effectiveness of the algorithm.
