Abstract

A method, an evaluation system and a cooperative vehicle for predicting at least one congestion parameter are proposed. The method involves a detecting of a traffic density 71 - 74 , a detecting of a current position x which is present during the detecting of the traffic density 71 - 74 and a relaying of the traffic density 71 - 74 and the current position x to an evaluation unit 60 . Moreover, the method includes an evaluation of the traffic density 71 - 74 and a providing of at least one congestion parameter.

First claim

The invention claimed is:

1. A method for predicting at least one congestion parameter, involving
detecting a traffic density with a detection unit of a cooperative vehicle;
detecting a current position (x) of the cooperative vehicle which is present during the detecting of the traffic density;
relaying of the traffic density and the current position (x) to an evaluation unit ( 60 );
evaluating the traffic density with the evaluation unit considering a vehicle-specific quality factor; and
providing of at least one congestion parameter with the evaluation unit,
wherein historical data is considered in the evaluation of the traffic density, wherein a current time variation is compared with historical time variations, and if there is a uniform deviation between the current and the historical data, a time variation of a current situation is extrapolated by adding a constant value to the historical data.

2. The method according to claim 1 , wherein the congestion parameter is a position of a congestion start and/or congestion end.

3. The method according to claim 1 , wherein the detecting of the traffic density is done in an approach zone of a traffic jam.

4. The method according to claim 1 , moreover involving considering of at least one approach parameter in the evaluation of the traffic density.

5. The method according to claim 1 , moreover involving weighting of a possible congestion avoidance route with a probability in the evaluation of the traffic density.

6. An evaluation system for predicting of at least one congestion parameter, having
a cooperative vehicle for providing a traffic density;
an evaluation unit for evaluating the traffic density; and
a transmission link from the cooperative vehicle to the evaluation unit and a transmission link from the evaluation unit to the cooperative vehicle; wherein
the cooperative vehicle has a detection unit for detecting of the traffic density and a current position of the cooperative vehicle which is present during the detection of the traffic density, and a transmission unit for relaying the traffic density and the current position (x) via the transmission link to the evaluation unit, wherein
the evaluation unit has a reception unit which is designed for receiving the traffic density and the current position (x) of the cooperative vehicle, wherein
with the evaluation unit the traffic density is evaluated considering a vehicle-specific quality factor; and
with the evaluation unit at least one congestion parameter is provided, wherein the evaluation unit is designed to evaluate the traffic density with the help of historical data, wherein the evaluation unit is further designed to compare a current time variation with historical time variations, wherein if there is a uniform deviation between the current and the historical data the evaluation unit is further designed to extrapolate a time variation of a current situation by adding a constant value to the historical data.

7. The evaluation system according to claim 6 , wherein the congestion parameter is a position of a congestion start and/or congestion end.

8. The evaluation system according to claim 6 , wherein detecting of the traffic density is done in an approach zone of a traffic jam.

9. The evaluation system according to claim 6 , wherein the evaluation unit considers at least one approach parameter in the evaluation of the traffic density.

10. The evaluation system according to claim 6 , wherein the evaluation unit is further configured to weigh a possible congestion avoidance route ( 80 ) with a probability in the evaluation of the traffic density.
