In-Time (Intelligent and Efficient Travel management for European Cities) focuses on Multimodal Real Time Traffic and Travel Information (RTTI) services with the goal to reduce drastically energy consumption in urban areas across the different modes of transport by changing the mobility behavior (modal shift) of the single traveler. In-Time provides mainly 2 end-user services: (1) Business-to-business services will enable European-wide Traffic Information Service Providers (TISPs) to get access to regional traffic and travel data and services of the single pilot cities via a harmonized standardized open interface. This will enable the TISP to provide interoperable and multimodal RTTI services (e-services) to their end-users. Eservices will influence the on-trip travel behavior by optimizing journeys taking the energy consumption into account. The community will be the users of mobile devices or navigational devices. (2) Web based interoperable and intermodal pre-trip information will be provided by the pilot operators and has the potential to influence the travel behavior in the trip planning stage by taking environmental aspects into account. The typical users are persons that are planning an urban trip on short term. Central part of the In-Time concept is an interoperable and multimodal Regional Data/Service Server (RDSS).
