DEVELOPMENT OF THE NEW TOYOTA NAVIGATION SYSTEM WITH VOICE ROUTE GUIDANCE

Toyota Motor Corporation developed a new navigation system featuring voice announcements. This system, mass-produced as O.E.M. equipment for the first time in the world, was installed on the Celsior, with marketing beginning in Japan in August 1992. Designed on the basis of detailed analysis of Japanese drivers' driving habits and the driving environment, this voice navigation system enabled accurate point-to-point navigation anywhere within Japan. Most notably, the system enhances driving safety by providing well-timed voice guidance, decreasing the frequency of display glance. This paper reportes the features of the system, the hardware configuration, involving details of navigation functions and guiding logic. It examines the driver's glance behavior at navigation display while driving and evaluates its effectiveness.
