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车载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，司机可以根据自己的特点，通过使用道路标志和汽车导航来保密地前往目的地。其次，建立了基于驾驶员路径规划推理模型的诱导信息评价模型。最后，明确了诱导标志数据库的结构，并建立了实际路网的部分数据库。

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.
