Intermodal passenger transport, also called mixed-mode commuting, involves using two or more modes of transportation in a journey. Mixed-mode commuting is often used to combine the strengths of various transportation options. A major goal of modern intermodal passenger transport is to reduce dependence on the automobile as the major mode of ground transportation and increase use of public transport. To assist the traveller, various intermodal journey planners such as Rome2rio and Google Transit have been devised to help travellers plan and schedule their journey.

Hercules station is a proposed intermodal infill train station and ferry terminal in Hercules, California in Contra Costa County. It is to be the first direct Amtrak-to-ferry transit hub in the San Francisco Bay Area and will be constructed in between the existing Richmond and Martinez stations. By July 2018, three of the station's six construction phases had been complete, including street at Bay Trail approaches. However, no proposed opening date has yet been announced by the City of Hercules.
