The invention relates to a layered fuzzy entrance ramp control method for relieving traffic jam, and belongs to the field of urban road traffic control. Firstly, expressway density, density variation, ramp inflow and queuing length are taken as input variables, ramp control flow is coordinated more comprehensively, and entrance ramp control efficiency is improved; secondly, a layered fuzzy reasoning model is used for adjusting the ramp control flow, the problem of rule explosion in standard fuzzy rule reasoning is solved, the system reasoning time is shortened, and the entrance ramp control flow is adjusted in real time; and finally, algebraic representation of the layered fuzzy inference model is carried out by using an existing autonomously proposed matrix semi-tensor product theory, fuzzification and defuzzification of a middle layer of the layered fuzzy inference model are omitted, the accuracy and interpretability of the model are improved, and the entrance ramp control flow is adjusted more accurately.
本发明涉及一种缓解交通拥堵的分层模糊入口匝道控制方法,属于城市道路交通控制领域;首先,以高速公路密度、密度变化量、匝道流入流量、排队长度为输入变量,更加全面的协调匝道控制流量,提高入口匝道控制效率;其次,利用分层模糊推理模型对匝道控制流量进行调整,解决了标准模糊规则推理中规则爆炸的问题,缩短了系统推理时间,更加实时的调整入口匝道控制流量;最后,利用现有自主提出的矩阵半张量积理论进行分层模糊推理模型的代数表示,省略了分层模糊推理模型的中间层的模糊化和解模糊化,提高了模型的准确度和可解释性,进而更加精准的调整入口匝道控制流量。
