Abstract: Efficient transportation systems are crucial for the ever-growing smart cities. With the increasing urbanization and growth in vehicular traffic, congestion has become a significant challenge. This research paper addresses the critical issue of identifying the fastest, least congested path in road transport networks, aiming to enhance overall travel efficiency and reduce the negative impact of traffic congestion. The study employs an improved version of the Lifelong Planning A* (LPA*) that helps find the fastest route between two points in dynamic changing environments. The proposed methodology is called the Lifelong Dynamic Timed A ∗ (LTA∗ ) algorithm with an optimal bound weight factor integrated with it to make the search more guided and efficiently predict optimized traffic paths to provide real-time recommendations. To validate the effectiveness of the de-veloped algorithm, extensive simulations and case studies are conducted on a small area in Washington as well as on Grid Worl ds. The experimental results show that LTA*, within accurate weight bounds, always managed to find the fastest path, and in some cases, the time taken was close to half of that produced by A. (More)
