A new road guidance system based on the "road sign mode" and guide sign data base system

本研究旨在明确道路标志系统与汽车导航系统结合的需求，并提出两者结合的实现方案。为此，我们明确了驾驶员可以根据自己的特点，利用路标和汽车导航，秘密地前往目的地。其次，基于驾驶员规划路径的推理模型，建立了诱导信息的评价模型。最后明确了路标数据库的结构，并建立了一个真实的道路网的部分数据库。

This research aims to clear the needs of the combination between road sign system and car navigation system and to propose the realization of the combination of them. For this purpose, we made clear that drivers can go to their destinations confidentially by making use of road signs and car navigation according to their features. Next we built the evaluation model of guidance information based on inference model of the drivers who planned the route. Lastly we made clear the structure of guide sign data-base and made a partial data-base of real road network.
