Abstract

A computer-implemented method for assessing traffic status with sensors is provided. The method includes receiving sensor readings from a plurality of mobile sensors for detecting a traffic parameter and obtaining traffic information associated with the received sensor readings. The method also includes identifying a change in traffic based on the obtained traffic information and the received sensor reading, and determining whether a traffic incident has occurred based on the identified change. Systems and machine-readable media are also provided.

Claims

1. A computer-implemented method for assessing traffic incidents with sensors, the method comprising:

receiving sensor readings from a plurality of mobile sensors for detecting a traffic parameter;

obtaining traffic information associated with the received sensor readings;

identifying a change in traffic based on the obtained traffic information and the received sensor readings;

determining, for each received sensor reading, that the received sensor reading is a false alarm if the received sensor reading does not match general traffic information around the location where the sensor reading is taken; and

determining, if at least one received sensor reading is not a false alarm, whether a traffic incident has occurred based on the identified change.

2. The method of claim 1, wherein the sensor readings are generated based on a change in the traffic parameter, wherein the change exceeds a predetermined threshold.

3. The method of claim 1, wherein the determining comprises determining that the traffic incident has occurred if the identified change exceeds a predetermined threshold.

4. The method of claim 1, wherein the sensor readings received from the plurality of mobile sensors are associated with locations within predetermined distances from each other, and wherein the identifying the change in the traffic comprises identifying the change in traffic based on the obtained traffic information and the sensor readings.

5. The method of claim 1, wherein the traffic parameter comprises at least one of speed, acceleration, location, or sound.

6. The method of claim 1, wherein the plurality of mobile sensors comprise at least one of speed sensor, an accelerometer, a GPS receiver, or a gyroscope.

7. The method of claim 1, wherein the traffic information is generated by crowd-sourcing.

8. The method of claim 1, wherein the traffic information is received from at least one of the Internet, cellular networks, television signals, radio signals or satellite signals.

9. The method of claim 1, further comprising receiving location information and temporal information associated with the sensor readings.

10. The method of claim 9, wherein the identifying the change further comprises identifying the change in the traffic based on the received location information and the temporal information.

11. The method of claim 1, wherein the traffic information comprises current traffic information and historical traffic information.

12. The method of claim 1, wherein at least one of the plurality of mobile sensors is associated with a vehicle participating in traffic.

13. The method of claim 1, wherein the change in the traffic comprises a change in general speed of the traffic.

14. The method of claim 1, wherein the traffic information associated with the received sensor readings comprises traffic information of traffic that is proximate to a location of one the received sensor readings.

15. The method of claim 1, further comprising, if determination is made that a traffic incident has occurred, providing for communicating the traffic incident to a user.

16. A system for assessing traffic status with sensors, the system comprising:

a memory storing executable instructions; and

a processor coupled to the memory configured to execute the stored executable instructions to;

receive, from a plurality of mobile sensors for detecting a traffic parameter, sensor readings generated based on a change in the traffic parameter;

obtain traffic information associated with the received sensor readings;

identify a change in traffic based on the obtained traffic information and the received sensor readings;

determine, for each received sensor reading, that the received sensor reading is a false alarm if the received sensor reading does not match general traffic information around the location where the sensor reading is taken;

determine, if at least one received sensor reading is not a false alarm, whether a traffic incident has occurred based on the identified change; and

if determination is made that a traffic incident has occurred, provide for communicating the traffic incident to a user.

17. The system of claim 16, wherein the change exceeds a predetermined threshold.

18. The system of claim 16, wherein the determining comprises determining that the traffic incident has occurred if the identified change exceeds a predetermined threshold.

19. The system of claim 16, wherein sensor readings received from the plurality of mobile sensors are associated with locations within predetermined distances from each other, and wherein the identifying the change in the traffic comprises identifying the change in traffic based on the obtained traffic information and the received sensor readings.

20. A machine-readable storage medium comprising instructions stored therein, which when executed by processors, cause the processors to perform operations comprising:

receiving, from a plurality of mobile sensors for detecting traffic parameters, a plurality of sensor readings generated based on changes in the traffic parameters, wherein the plurality of sensor readings are associated with locations within predetermined distances from each other;

obtaining traffic information associated with the received sensor readings;

if more than a predetermined number of the plurality of sensor readings is received, identifying a change in traffic based on the obtained traffic information and the received sensor readings;

determining, for each received sensor reading, that the received sensor reading is a false alarm if the received sensor reading does not match general traffic information around the location where the sensor reading is taken;

determining, if at least one received sensor reading is not a false alarm, whether a traffic incident has occurred based on the identified change; and

if determination is made that a traffic incident has occurred, providing for communicating the traffic incident to a user.
