This study develops a compact elasticity-based framework for assessing how autonomous truck adoption influences corridor-level performance, freight demand, modal competition, and CO2<\/sub>\u00a0emissions in multimodal freight Intelligent Transportation Systems. The model specifies the constant elastic (log-linear) responses of traffic performance and generalized costs to adoption, enabling the closed-form characterization of system-level rebound and road\u2013rail reallocation effects. The analytical results show that an internal adoption threshold\u00a0\ud835\udc43<\/span>\u2217<\/span><\/span><\/span><\/span><\/span><\/span>\u00a0emerges, defined by\u00a0\ud835\udc51<\/span>\ud835\udc38<\/span>\u0302\u00a0<\/span><\/span>\/<\/span>\ud835\udc51<\/span>\ud835\udc43<\/span>=<\/span>0<\/span><\/span><\/span><\/span><\/span><\/span>, which separates a beneficial regime (efficiency gains dominate) from an adverse regime (rebound and modal shift dominate). Comparative statics indicate that\u00a0\ud835\udc43<\/span>\u2217<\/span><\/span><\/span><\/span><\/span><\/span>\u00a0decreases with stronger ITS capability\u00a0A<\/span>\u00a0and increases with rebound intensity\u00a0R<\/span>\u00a0and the road\u2013rail carbon intensity contrast\u00a0K<\/span>. Numerical experiments across representative corridor contexts illustrate induced demand effects exceeding 25% under high-rebound conditions and threshold ranges around\u00a0\ud835\udc43<\/span>\u2217<\/span><\/span>\u2248<\/span>0.3<\/span><\/span><\/span><\/span><\/span><\/span>\u20130.4 for plausible parameters. The results provide interpretable guidance for coordinating autonomous truck deployment with intermodal logistics design and decarbonization strategies.<\/dt>\n
