- Retrieving (S220) information regarding available electronic sensor devices (100: 1 , 100:2, 100:3, 100:4) at the location of the traffic accident and its surrounding area;

- Activating (S230) at least one of said available electronic sensor devices to send any traffic accident data recorded at a time interval comprising the time for the traffic accident to the traffic information service;

- Receiving (S240), organizing and storing any traffic accident data recorded at the time interval comprising the time for the traffic accident.

13. The method according to claim 12, wherein the information regarding available electronic sensor devices at the location of the traffic accident and its surrounding area is retrieved from an electronic storage connected to or accessible from the electronic sensor device.

14. The method according to claim 12 or 13, wherein the retrieving step (S220) further comprises:

- Connecting (S220: 1 ) to a Resource Directory, RD, (40) storing information regarding the location of available electronic sensor devices;

- Sending (S220:2) to the RD a request for information regarding available electronic sensor device at the location of the traffic accident and in it surrounding area;

- Receiving (S220:3) the requested information from the RD.

15. The method according to any of claim 12 - 14, wherein the activating step (S230) further comprises:

- Notifying (S230: 1 ) available electronic sensor devices at the location of the traffic accident and its surrounding area by broadcasting or multicasting a notification message.

16. The method according to claim 15, wherein the notification message comprises a unique identifier which identifies the sender (100, 100:2, 100:3, 100:4) and the time when the accident was detected.
