Abstract

The present disclosure relates to methods and devices for processing traffic data. A method may include acquiring a current location of a traveling vehicle. A method may further include, when the current location is not an identified traffic impediment location, monitoring an amount of variation of an impediment parameter when the vehicle is in the current location. A method may further include, when the amount of variation of the impediment parameter exceeds a predetermined range, sending the current location and the amount of variation of the impediment parameter to a traffic data server. Through a method, drivers may in real time learn accurate information about traffic impediments ahead, and may preemptively respond by lowering traveling speeds or bypassing the location.

6. The method of claim 5, wherein the method further comprises:

receiving from a user an inquiry request inquiring about an identified traffic impediment location on the traveling route;

sending the inquiry request to the traffic data server;

receiving traffic impediment data of the identified traffic impediment location, the received traffic impediment data of the identified traffic impediment location being a result of a search by the traffic data server based on the inquiry request; and

presenting the received traffic impediment data of the identified traffic impediment location.

7. A method for processing traffic data, applied in a server, the method comprising:

receiving, from a first vehicle, a current location of the first vehicle and an amount of variation of an impediment parameter of the first vehicle;

determining whether the current location corresponds to a location previously stored in a traffic-impediment-location list in the server; and

when the current location does not correspond to a location previously stored in the traffic-impediment-location list;

identifying the current location as a traffic impediment location,

storing the amount of variation of the impediment parameter locally in the server, and

storing the current location in the traffic-impediment-location list.

8. The method of claim 7, wherein the method further comprises:

receiving, from a second vehicle, a traveling route of the second vehicle;

determining whether an identified traffic impediment location exists on the traveling route; and

when an identified traffic impediment location exists on the traveling route, sending to the second vehicle;

each identified traffic impediment location on the traveling route, and

a respective predetermined range of an impediment parameter corresponding to each identified traffic impediment location.

9. The method of claim 7, wherein the method further comprises:
