摘要
将案例推理技术引入到快速路上可变信息牌的信息发布策略中,利用以往具体案例的经验来解决当前新的信息发布问题。首先对北京市环路上可变信息牌的使用进行了评述,在此基础上提出了基于案例推理的快速路可变信息牌的信息发布策略。详细讨论了基于决策树的案例组织方法和基于模糊推理的案例修正方法。基于案例推理的信息发布策略能够及时准确地把相关信息发布给驾驶员,从而提高出行效率。
The case-based reasoning is introduced into information issuing strategy of variable message signs, solving the current infor- mation issuing problem by using the former case experience. Firstly, the variable message signs on Beijing ring roads are reviewed, a strategy for information issuing of VMS based on case-based reasoning is proposed. Secondly, the case organization method based on the decision tree and case revise method based on the fuzzy reasoning are discussed in detail. The strategy for information issuing based on CBR can promptly issue the accurate information for drivers, thus enhance the journey efficiency.
