Travel　mode　structure　optimisation　is　the　intervention　on　travel　behaviour.　The　existing　theory　and　method　of　travel　mode　structure　optimisation　ignore　the　research　about　traveller＇s　acceptance　level　and　behaviour　change,　which　makes　optimal　objective　difficult　to　be　achieved.　Starting　from　the　basic　theory　of　behaviour　change,　the　basic　model　of　travel　behaviour　change　is　constructed.　Acceptance　level　is　the　determinant　factor　of　travel　behaviour　change.　The　theoretical　mathematical　model　of　travel　mode　structure　optimisation　is　presented　and　the　model　of　travel　behaviour　change　is　used　for　travel　mode　structure　optimisation.　The　macro-model　of　travel　mode　structure　optimisation,　which　is　based　on　the　theory　of　travel　behaviour　change,　is　constructed.　Traveller　acceptance　model　for　intervention　measure　is　constructed　and　empirical　research　is　carried　out　in　Jiaozuo　city.　The　result　indicates　that　the　theory　of　travel　mode　structure　optimisation　considering　traveller＇s　acceptance　level　has　better　applicability.　©　2013　Inderscience　Enterprises　Ltd.
