【摘要】：為提高路況信息獲取的預(yù)知性和路徑引導(dǎo)的時(shí)效性,首先綜合車輛運(yùn)行過程中不同時(shí)段的路況差異和人因作用,運(yùn)用時(shí)間遞推原理,構(gòu)建交通路徑動(dòng)態(tài)誘導(dǎo)整體結(jié)構(gòu)模型,比較知識(shí)庫(kù)累積經(jīng)驗(yàn)路徑與實(shí)時(shí)路況信息,為駕駛?cè)说臅r(shí)間最短通行路徑選擇提供信息支撐;然后基于有師學(xué)習(xí)思路,對(duì)路徑誘導(dǎo)邏輯內(nèi)核結(jié)構(gòu)進(jìn)行解析,給出局部繞行和整體繞行2種算法實(shí)現(xiàn)的偽代碼;最后通過對(duì)不同時(shí)刻出行和相同時(shí)刻出行的實(shí)例仿真分析,驗(yàn)證模型及程序的可靠性。研究結(jié)果表明:該交通路徑動(dòng)態(tài)誘導(dǎo)方法可輔助駕駛?cè)思皶r(shí)對(duì)路況做出正確判斷,減少因經(jīng)驗(yàn)不足和突發(fā)事件造成的時(shí)間損失,適用于安裝有GPS導(dǎo)航的車輛。
[Abstract]:In order to improve the predictability of road condition information acquisition and the timeliness of route guidance, firstly, by synthesizing the road condition difference and human factor action in different periods of time during vehicle operation, the whole structure model of dynamic guidance of traffic path is constructed by using the principle of time recursion.Comparing the accumulated empirical path with the real-time road condition information in the knowledge base to provide the information support for the driver's shortest passage path selection, and then based on the teacher-learning idea, analyze the path inducing logic kernel structure.The pseudo codes of local detour and global detour are given. Finally, the reliability of the model and program is verified by the simulation analysis of different travel at different times and the same travel at the same time.The results show that the method can help the driver to judge the road condition correctly and reduce the loss of time caused by the inexperience and unexpected events. It is suitable for the vehicle with GPS navigation.
