Research of Car Navigation Data Retrieval System

Abstract

In recent years, the automotive industry has become a pillar industry of the world, the role played by the automobile in the daily life and work has become increasingly prominent. In the car navigation retrieval system, whether from the perspective of retrieval speed, screen display, or memory management, it can not meet the needs of users. In the design, the retrieval algorithm along the road of facilities retrieval can not only improve the retrieval system's modular structure, but also introduce the idea of thread pool. The whole system is divided into four modules; B-Tree + phenotype data structures being used can improve the search speed; a new road merging algorithm being proposed can improve the retrieval performance.
