Methods and systems for vehicle alerting based on the functional classification of roads
A method for vehicle alerting includes receiving, at a cloud computing system, digital data that includes a location of a vehicle and a hazard lights on status of the vehicle, determining a functional classification of a road that corresponds to the location of the vehicle, wherein the digital data is received from the vehicle via a wireless connection, and determining whether to initiate an alert messaging operation in response to the functional classification of the road and the hazard lights on status, wherein determining whether to initiate the alert messaging operation involves selecting from available options of 1) initiating the alert messaging operation when the functional classification of the road is determined to be within a first set of functional classifications, and 2) not initiating the alert messaging operation when the functional classification of the road is determined to be within a second set of functional classifications.
1. A method for alerting vehicles, the method comprising:
receiving, at a cloud computing system, digital data that includes a location of a vehicle and a hazard lights on status of the vehicle;
determining, by the cloud computing system, a functional classification of a road that corresponds to the location of the vehicle, wherein the digital data is received from the vehicle via a wireless connection; and
determining, by the cloud computing system, whether to initiate an alert messaging operation in response to the functional classification of the road and the hazard lights on status;
wherein determining whether to initiate the alert messaging operation involves selecting from available options of:
initiating the alert messaging operation when the functional classification of the road is determined to be within a first set of functional classifications; and
not initiating the alert messaging operation when the functional classification of the road is determined to be within a second set of functional classifications.
2. The method of claim 1 , wherein the first set of functional classifications includes FC1-FC3, and wherein the second set of functional classifications includes FC4-FC7.
3. The method of claim 1 , wherein the first set of functional classifications includes interstate, other freeways or expressways, and other principal arterial roadways, and wherein the second set of functional classifications includes minor arterial, major collector, minor collector, and local roadways.
4. The method of claim 1 , wherein functional classifications of roads are functional classifications as defined by a government transportation agency.
5. The method of claim 1 , wherein the digital data received at the cloud computing system includes a hazard lights status field.
6. The method of claim 1 , wherein the digital data received at the cloud computing system includes a hazards lights on code.
7. The method of claim 1 , wherein the hazard lights on status corresponds to hazard lights being activated on the vehicle.
8. The method of claim 1 , wherein the alert messaging operation involves indicating that an alert message should be wirelessly transmitted in an alerting zone around the location of the vehicle.
9. The method of claim 8 , further comprising determining vehicles that are within the alerting zone, and transmitting the alert message to those vehicles within the alerting zone.
10. The method of claim 1 , wherein the digital data is included in a vehicle data message that includes:
a vehicle identifier (ID) that corresponds to the vehicle;
location information that corresponds to the location of the vehicle; and
a hazard lights on code that indicates the vehicle has hazard lights on.
11. A non-transitory computer readable medium comprising instructions to be executed in a computer system, wherein the instructions when executed in the computer system perform a method comprising:
receiving, at a cloud computing system, digital data that includes a location of a vehicle and a hazard lights on status of the vehicle;
determining, by the cloud computing system, a functional classification of a road that corresponds to the location of the vehicle, wherein the digital data is received from the vehicle via a wireless connection; and
determining, by the cloud computing system, whether to initiate an alert messaging operation in response to the functional classification of the road and the hazard lights on status;
wherein determining whether to initiate the alert messaging operation involves selecting from available options of:
initiating the alert messaging operation when the functional classification of the road is determined to be within a first set of functional classifications; and
not initiating the alert messaging operation when the functional classification of the road is determined to be within a second set of functional classifications.
