The type of navigation-systems available nowadays varies a lot. Although a lot of these systems
provide the user with a choice between several means of transportations and calculation types,
the transportation type, for example bus or train, remains static during route guidance. This induces
the inability to dynamically react to bus delays or deviations from the travel time. Enav enables wheelchairs
users to profit from real time information on bus delays.
In this work a concept for calculating and notifying about better routes during route guidance is introduced,
resulting in faster as well as more energy efficient routes for wheelchair users. This is indicated
by an evaluation at the end of this work. In the evaluation several route types are analyzed and
discussed.
