Fuzzy Control Strategy of Tunnel Lighting Based on Input Parameter Optimization

Abstract The mismatch between illumination and traffic safety brightness in tunnels leads to much-wasted lighting energy problems. Effective control of tunnel can be achieved by on demand reducing consumption. This paper uses the curve fitting linear interpolation methods optimize luminance reduction factor K proposed Highway Tunnel Lighting Rules. It constructs a multi-zone division speed, flow, outside obtain value under actual road conditions establish fuzzy controller for dimming control. simulation demonstrates that strategy save about 37.38% compared graded strategy.
