Within the last years, the availability of mobile Internet connections has been increased significantly. Nevertheless, the impact of this ubiquitous Web access has not arrived at road user information systems with a few exceptions for navigation systems or traffic monitoring. Even those services that are available today are very limited, as they mainly use GPS or TMC information combined with Web-based maps. Making full use of the Internet availability can enable a whole range of new services and apps for road users, helping them to make their journey safer, more comfortable, and more environmental friendly.In this talk, we will identify current research gaps in road user information systems, namely the need to overcome heterogeneous and missing interoperability of relevant data sources, a missing end-to-end integration of data and functionality, and the demand for a homogeneous, unified user interface to road user information systems. Eventually, we will present some results from the ongoing EU FP7 project SIMPLICITY - The Road User Information System of the Future, which contributes to solve these issues.
