Abstract:

As the traffic congestion becomes more and more serious, the public evaluation standard for the road quality during driving changes greatly. How to avoid congestion to find the best way to travel has become an important scientific issue and social issue urgent to address in the context of building a smart city. Thus this paper first defines the novel concept of optimal path with multi-constraints and models it. Then, in order to solve the proposed model more efficiently, we improve the state transition rules of the heuristic function and pheromone update operator based on the classical ant colony algorithm by increasing the path optimization algorithm's awareness of real-time path quality information, such as traffic conditions, resulting in the strong dynamic adjustment ability of our proposed path optimization algorithm to path information. Simulation results show that our proposed ant colony algorithm can find the optimal path with multi-constraints more accurately and more quickly than other ant colony algorithms.
