Physical (or spatial) integration describes efforts to locate the various parts of a transport system in proximity to each other. Examples include placing parking for shared mobility vehicles in direct proximity to a public transit spot. Also visual features, like signs or visually indicated zones on the ground can increase physical integration.
Digital integration describes the effort of integrating information on one digital platform and making it possible for different information platforms to access information using a standard format. Through digital integration, users are able to easily access information provided by multiple providers in one place. Examples are travel planners that let users identify services provided by different providers or platforms that let users plan, book and pay for services of different providers in one application.
