%X Accurate and fast path calculation is essential for applications such as vehicle navigation systems and transportation network routing. Although many shortest path  algorithms for restricted search areas have been developed in the past ten years to  speed up the efficiency of path query, the performance including the practicability  still needs to be improved. To settle this problem, this paper proposes a new method  of calculating statistical parameters based on a unidirectional road network model  that is more in line with the real world and a path planning algorithm for  dynamically restricted search areas that constructs virtual boundaries at a lower  confidence level. We conducted a detailed experiment on the proposed algorithm with  the real road network in Zhengzhou. As the experiment shows, compared with the  existing algorithms, the proposed algorithm improves the search performance  significantly in the condition of optimal path under the premise of ensuring the  optimal path solution.<p /> <p>Language: en</p>
