Because　of　the　special　traffic　environment,　the　tunnel　is　called　a　bottleneck　on　the　highway　sections;　there　is　a　huge　risk　of　safe　operation.　Tunnel　interior　zone　lighting　plays　an　important　role　in　the　tunnel;　good　lighting　can　eliminate　depression　and　driving　fatigue　of　the　driver　in　the　tunnel.　In　this　paper,　freeway　tunnel　interior　zone　lighting　is　as　the　research　object.　We　analyzed　the　driver＇s　demand　for　freeway　tunnel　interior　zone　lighting　and　transformed　illumination　to　luminance　in　the　model　of　driver　workload,　operating　speed　and　the　illumination.　And　this　model　is　established　by　our　group.　According　to　comfortable　and　relatively　comfortable　driving　workload　intense　threshold,　we　can　get　the　safe　and　comfortable　luminance　threshold　of　tunnel　interior　zone.　This　paper　proposed　a　detection　and　evaluation　method　in　freeway　tunnel　interior　zone　luminance,　and　the　method　have　been　applied　and　verified　on　one　freeway　in　south　China.
