Traffic probe device selection
Traffic probe devices, for validating traffic flow information, are selected by determining if a traffic probe device has a driver associated therewith traveling on an entire roadway segment of interest and whether the traffic probe device travelled continuously on the entire roadway segment of interest. The method continues by adding the traffic probe device to a list of traffic probe devices. The method continues by receiving measurements, during a particular time, from one or more of the traffic probe devices on the list of traffic probe devices, validating traffic-flow information for the roadway segment of interest, the traffic-flow information associated with the one or more of the traffic probe devices on the list of traffic probe devices and the particular time, and disseminating traffic messages including at least the validated traffic-flow prediction to users.
1. A method of selecting a traffic probe device for traffic-flow validation, the method comprises:
determining if a traffic probe device has a driver associated therewith traveling on a roadway segment of interest;
determining if the traffic probe device travel path includes an entire roadway segment of interest;
determining, whether the traffic probe device travelled continuously on the entire roadway segment of interest;
adding, for determinations of travelled continuously on the entire roadway segment of interest, the traffic probe device to a list of traffic probe devices while ignoring the traffic probe device if it encountered a status including any of: stopped, detoured, or entered after a beginning of the entire roadway segment of interest;
receiving input from one or more of the traffic probe devices on the list of traffic probe devices, the input including traffic-related measurements during a particular time;
validating, based on the traffic-related measurements, traffic-flow information for the roadway segment of interest, the traffic-flow information associated with the one or more of the traffic probe devices on the list of traffic probe devices and the particular time; and
outputting traffic messages including at least the validated traffic-flow information to at least one users device.
2. The method of claim 1 , wherein the traffic probe device having no driver associated therewith traveling on a roadway segment of interest is determined to be irrelevant.
3. The method of claim 1 further comprises selecting a next traffic probe device for processing until there are no more of the traffic probe devices to process.
4. The method of claim 1 further comprises ignoring a traffic probe device if the traffic probe device did not travel on a continuous artery.
5. The method of claim 1 , wherein the list of traffic probe devices is generated by adding traffic probed devices to define a set of traffic probe devices that will be used to validate the traffic-flow information.
6. A system comprising: a traffic validation module implemented using a processor and associated memory, the traffic validation module configured to:
select traffic-related measurements obtained from particular traffic probe devices, the particular traffic probe devices selected by:
determine if a traffic probe device has a driver associated therewith traveling on a roadway segment of interest;
determine if the traffic probe device travel path includes an entire roadway segment of interest;
determine, whether the traffic probe device travelled continuously on the entire roadway segment of interest;
add, for determinations of travelled continuously on the entire roadway segment of interest, the traffic probe device to a list of traffic probe devices while ignoring the traffic probe device if it encountered a status including any of: stopped, detoured, or entered after a beginning of the entire roadway segment of interest;
receive input from one or more of the traffic probe devices on the list of traffic probe devices, the input including traffic-related measurements during a particular time;
validate, based on the traffic-related measurements, traffic-flow information for the roadway segment of interest, the traffic-flow information associated with the one or more of the traffic probe devices on the list of traffic probe devices and the particular time; and
output traffic messages including at least the validated traffic-flow information to at least one users device.
7. The system of claim 6 , wherein the traffic probe device having no driver associated therewith traveling on a roadway segment of interest is determined to be irrelevant.
8. The system of claim 6 , wherein the traffic validation module is further configured to select a next traffic probe device for processing until there are no more traffic probe devices to process.
9. The system of claim 1 , wherein the traffic validation module is further configured to ignore a traffic probe device if the traffic probe device did not travel on a continuous artery.
10. The system of claim 6 , wherein the list of traffic probe devices is generated by adding traffic probes to define a set of traffic probe devices that will be used to generate the traffic-flow measurement information.
11. The system of claim 10 , wherein the list of traffic probe devices is used in validating traffic data for the traffic-flow information associated with the road segment of interest.
12. A non-transitory computer readable medium tangibly embodying a program of instructions to be stored in a memory and executed by a processor, the program of instructions configured to select a traffic probe device for inclusion in traffic-flow validation, the program of instructions configured to:
determine if a traffic probe device has a driver associated therewith traveling on a roadway segment of interest;
determine if the traffic probe device travel path includes an entire roadway segment of interest; determine, whether the traffic probe device travelled continuously on the entire roadway segment of interest;
add, for determinations of travelled continuously on the entire roadway segment of interest, the traffic probe device to a list of traffic probe devices while ignoring the traffic probe device if it encountered a status including any of: stopped, detoured, or entered after a beginning of the entire roadway segment of interest;
receive input from one or more of the traffic probe devices on the list of traffic probe devices, the input including traffic-related measurements during a particular time;
validate, based on the traffic-related measurements, traffic-flow information for the roadway segment of interest, the traffic-flow information associated with the one or more of the traffic probe devices on the list of traffic probe devices and the particular time; and
output traffic messages including at least the validated traffic-flow information to at least one users device.
13. The non-transitory computer readable medium of claim 12 , wherein the list of traffic probe devices is generated by adding traffic probes to define a set of traffic probe devices that will be used to generate the traffic-flow measurement information.
