| Abstract: | A nonlinear approach is proposed for designing a feedback ramp controller in freeway.The nonlinear feedback controller is composed of a freeway traffic flow model and a proportional-plus-integral regulator.The control principle of a ramp is formulated.The freeway traffic flow model for the ramp control was developed,the model's flow-density relationship is nonlinear,and the model of nonlinear feedback controller is built.Simulation results show that the nonlinear feedback controller is of high performance.It can achieve a desired traffic density along the mainline of a freeway while maintaining an acceptable ramp service level. |
| Keywords: | freeway on-ramp traffic flow model nonlinear feedback simulation |
