交通信號(hào)的實(shí)時(shí)公平調(diào)度及其仿真

1、交通信號(hào)的實(shí)時(shí)公平調(diào)度及其仿真交通信號(hào)的實(shí)時(shí)公平調(diào)度及其仿真摘要:交通信號(hào)的實(shí)時(shí)調(diào)度是改善交通擁堵的重要途徑之一，其公平性研究同樣至關(guān)重要。針對(duì)通信網(wǎng)絡(luò)和交通網(wǎng)絡(luò)的共同特點(diǎn)，借鑒其最大最小公平和比例公平的思想，分別提出最小最大公平、比例公平交通信號(hào)實(shí)時(shí)調(diào)度算法；并與優(yōu)化隊(duì)列長度的實(shí)時(shí)調(diào)度、固定周期調(diào)度算法進(jìn)行仿真對(duì)比。實(shí)驗(yàn)結(jié)果表明，優(yōu)化隊(duì)列長度的實(shí)時(shí)調(diào)度和固定周期調(diào)度會(huì)使得部分車輛等待時(shí)間過長而表現(xiàn)出不公平；最小最大公平調(diào)度表現(xiàn)出最好的

2、公平性，但在網(wǎng)絡(luò)高密度下平均時(shí)延表現(xiàn)較差；比例公平調(diào)度則在各種交通密度下同時(shí)表現(xiàn)出較低的平均時(shí)延和較好的公平性。研究結(jié)果為實(shí)時(shí)交通信號(hào)的公平調(diào)度提供了解決方案，具有較好的應(yīng)用價(jià)值。關(guān)鍵詞:比例公平調(diào)度；交通信號(hào)；實(shí)時(shí)調(diào)度；智能交通；公平性equityreal.timetrafficsignalschedulingalgithmlihuiguoai.huangschoolofelectronicinfmationengineeringto
