Intelligent Offloading Strategies For High Throughput Traffic Intersection Coordination

Abstract

Appropriate traffic coordination at road intersections plays a crucial part in modern intelligent transportation systems (ITS). However, in some existing coordination algorithms, the complexity is too high to achieve real time solutions, that restricts their applications. Therefore, we try to propose an efficient computation offloading method based on an optimal coordination framework, by which the traffic throughput can be maximized [1]. Two different objective functions are adopted to make the computation simultaneously, under the constraints of the traffic statistics and communications capabilities. Numerical results show that both strategies can reduce the computation time of the system by approximate 20%. Additionally, as the computation capability of vehicles increases, the optimal offloading schemes achieved by the two proposed strategies may vary accordingly.
