    摘要:

    高速公路交通流特征復雜多變,受到諸多影響因素的共同作用,如天氣、道路狀況、車(chē)輛類(lèi)型等等。因此,如何獲取交通流邏輯控制條件并實(shí)現精準調節難度較大。為此,本研究設計新的高速公路實(shí)時(shí)交通流模糊邏輯優(yōu)化控制系統。對于系統的硬件部分,設計車(chē)流控制模塊、無(wú)線(xiàn)傳輸車(chē)載終端、實(shí)時(shí)交通流邏輯調度模塊、模糊控制器模塊,并確定各個(gè)模塊之間實(shí)時(shí)連接關(guān)系。對于系統的軟件部分,求解交通流邏輯控制條件,聯(lián)合高速公路實(shí)時(shí)通行相位條件,調節模糊控制器,并根據高速公路交通路網(wǎng)模型,推導交通流優(yōu)化控制條件的求解表達式,完成高速公路實(shí)時(shí)交通流模糊邏輯優(yōu)化控制系統的設計。實(shí)驗結果表明,本系統可以解決邏輯協(xié)調錯誤的問(wèn)題,且能夠有效控制高速公路車(chē)流量。

    Abstract:

    The characteristics of expressway traffic flow are complex and changeable, which are influenced by many factors, such as weather, road conditions, vehicle types and so on. Therefore, it is difficult to obtain the traffic flow logic control conditions and achieve accurate adjustment. Therefore, a new fuzzy logic optimization control system for expressway real-time traffic flow is designed in this paper. For the hardware part of the system, design the traffic flow control module, wireless transmission vehicle terminal, real-time traffic flow logic scheduling module, fuzzy controller module, and determine the real-time connection between each module. As for the software part of the system, the logic control conditions of traffic flow are solved, the real-time traffic phase conditions of expressways are combined, the fuzzy controller is adjusted, and the expression of the optimization control conditions of traffic flow is derived according to the traffic network model of expressways, and the design of the fuzzy logic optimization control system of real-time traffic flow of expressways is completed. The experimental results show that the system can solve the problem of logic coordination error, and can effectively control the highway traffic flow.
