Abstract

A method of evaluating traffic information transmitted by a traffic information service, in which data on the traffic situation on a route to be traveled in the present direction of travel is received and, from the data on the traffic situation, an anticipated delay in journey time on the route to be travelled is calculated. In order to avoid unnecessary waiting in traffic hold-ups it is provided that the size of the calculated anticipated delay in journey time together with a recommendation to interrupt the journey is displayed if the anticipated delay in journey time in the present direction is greater than a given value.

Claims

1. Method of evaluating traffic information transmitted by a traffic information service, in which:

data on the traffic situation on a route to be travelled in the present direction of travel is received and

from the data on the traffic situation an anticipated delay in journey time on the route to be travelled is calculated,

characterised in that

the size of the calculated anticipated delay in journey time together with a recommendation to interrupt the journey is displayed if the anticipated delay in journey time in the present direction is greater than a given value.

2. Method according to claim 1, characterised in that

before the recommendation to interrupt the journey is displayed an alternative route is worked out and an alternate route delay in journey time using the alternative route is calculated; and

the display of the recommendation to interrupt the journey is output if a shortest of the anticipated delay and the alternate route delay in journey time is greater than the given value.

3. Method according to claim 1, characterised in that the given value can be pre-determined by a user.

4. Method according to claim 1, characterised in that routing to a specific interesting point on route is offered, if a visit time needed for a visit to the interesting point on route as a given value is less than the anticipated delay in journey time.

5. Method according to claim 4, characterised in that the visit time needed for the visit to the interesting point on route is calculated from the length of the journey there and back and from a pre-determinable or pre-determined length of stay at the interesting point on route.

6. Method according to claim 4, characterised in that in calculating the visit time needed for the visit to the interesting point on route, the types of roads to be used on the way to the interesting point on route are taken into account.

7. Method according to claim 4, characterised in that in calculating the visit time needed for the visit to the interesting point on route, the previous driving behaviour of the user is taken into account.

8. Method according to claim 4, characterised in that the interesting points on route are pre-determinable by the user.

9. Method according to claim 4, characterised in that categories of interesting points on route are pre-determinable by the user.
