FIELD: physics, navigation.SUBSTANCE: invention relates to navigation systems. The device includes means of determining a first route based on a traffic situation and for determining a second route taking into account change in the road situation, means for determining a measure of the effect of change in the road situation on the route, decision means for deciding on whether said measure (TDV) exceeds the effect of a first threshold value given by a user, and output means for offering the user two routes for selection for further navigational guidance if the measure of the effect of the first threshold value is exceeded.EFFECT: high accuracy of estimating measures of effect of the road situation on a route.9 cl, 6 dwg |
