Caspar G. Chorus and Harry J.P. Timmermans INTRODUCTION Recently, rapid technological developments in mobile communications and satellite technology have provided a vision among telecommunication companies, transport agencies, governments and academia of a technological revolution in Advanced Traveler Information Systems towards what can be called a Personal Intelligent Travel Assistant (PITA). Where the term ATIS has been used since the late 1980s to describe a range of travel information systems and services of varying degrees of sophistication, PITA distinguishes itself from the current generation of ATIS in terms of one or more of the following features (Chorus, 2007): ● ● ● ● PITA provides dynamic information. That is, based on real-time monitoring of the transportation system and fed into cutting edge models of travel demand and network capacity to predict the state of the network in the near future. As such, PITA is able to provide information that is more reliable than information provided by information systems that use static or historic network data, or use realtime monitoring but fail to translate this data into meaningful predictions of the future state of the transport network. PITA provides personalized, mobile information. That is, PITA bases the information it provides on an accurate assessment of the traveler’s preferences, his or her location in the transport network and the constraints he or she faces (in terms of his or her schedule for the day, but also in terms of, for example, transit season ticket ownership and/or car availability). When deemed necessary, based on an assessment of the state...
