基于模糊逻辑工具箱的高速公路匝道控制，匝道控制有关的许多概念都具有模糊性，如交通状况(畅通、饱和、拥挤、堵塞等)、匝道排队长度、流量大小、车流稳定性等。本文用MATLAB模糊逻辑工具箱设计高速公路入口匝道控制器，并进行了仿真研究。
English Description：
Ramp control of Expressway Based on fuzzy logic toolbox, many concepts related to ramp control are fuzzy, such as traffic condition (smooth, saturated, congested, blocked, etc.), queue length of ramp, flow size, traffic stability, etc. In this paper, the fuzzy logic toolbox of MATLAB is used to design the controller of freeway on ramp, and the simulation is carried out.
