Abstract

A method is provided for ascertaining at least one road-related information item, including the following steps:

• • ascertaining a position of a location on a road, starting from which a mobile user device of a communication network crossed the road, based on the position data of the user device,
  • ascertaining a waiting time during which the user device had to wait at the location before the user device crossed the road,
  • ascertaining a position of a light signal system as a road-related information item, based on the ascertained waiting time and the ascertained position.

A corresponding system is also provided, as well as a corresponding computer program.

Claims

1. A method for ascertaining at least one road-related information item, comprising:

ascertaining a position of a location on a road, starting from which a mobile user device of a communication network crossed the road, based on position data of the user device;

ascertaining a waiting time during which the user device had to wait at the location before the user device crossed the road; and

ascertaining a position of a light signal system as the road-related information item, based on the ascertained waiting time and the ascertained position.

2. The method as recited in claim 1, further comprising:

ascertaining a speed of the user device at least one of before the crossing, during the crossing, and after the crossing;

based on the ascertained user device speed; and

ascertaining a type of light signal system as another road-related information item.

3. The method as recited in claim 1, further comprising:

ascertaining a crossing direction of the user device; and

based on the ascertained crossing direction, ascertaining an orientation of the light signal system as another road-related information item.

4. The method as recited in claim 1, further comprising, based on the ascertained waiting time, ascertaining a duration of a red phase of the light signal system as another road-related information item.

5. The method as recited in claim 1, further comprising ascertaining a crossing time that a user requires for crossing the road.

6. The method as recited in claim 1, further comprising ascertaining a date for the ascertained waiting time.

7. The method as recited in claim 1, further comprising:

in the case of a plurality of user devices, ascertaining a time that has passed between a first user device and a last user device being still able to cross the road before an additional user device had to wait again before crossing; and

based on the ascertained waiting time, ascertaining a duration of a green phase of the light signal system as another road-related information item.

8. A system for ascertaining at least one road-related information item, comprising:

a processing device that;

ascertains, based on position data of a mobile user device of a communication network, a position of a location on a road, starting from which the user device crossed the road,

ascertains a waiting time during which the mobile user device had to wait at the location before the user device crossed the road, and

ascertains a position of a light signal system as the road-related information item, based on the ascertained waiting time and the ascertained position.

9. A system as recited in claim 8, further comprising a communication interface for receiving the position data of the user device over the communication network.

10. A computer program that is run on a computer, comprising program code for implementing a method for ascertaining at least one road-related information item, comprising:

ascertaining a position of a location on a road, starting from which a mobile user device of a communication network crossed the road, based on position data of the user device;

ascertaining a waiting time during which the user device had to wait at the location before the user device crossed the road; and

ascertaining a position of a light signal system as the road-related information item, based on the ascertained waiting time and the ascertained position.
