Obtaining road traffic condition data from mobile data sources
First Claim
1. A computer-implemented method for automatically providing data samples from vehicles traveling on roads for use in assessing traffic conditions on those roads, the method comprising:
- for each of multiple vehicles traveling on one or more roads, providing information regarding travel of the vehicle by, for each of multiple successive periods of time of pre-determined length, acquiring multiple data samples during the period of time from a geo-location device traveling with the vehicle, each data sample being acquired at a distinct acquisition time during the period of time and including a reported geographic location and speed of the vehicle at that acquisition time;
temporarily storing the multiple data samples during the period of time in a storage device; and
at the end of the period of time, sending the multiple stored data samples together in a single data transmission via a wireless data transmitter to a remote traffic information system that is configured to use at least some of the data samples for facilitating travel of other vehicles on the one or more roads; and
removing the multiple stored data samples from the storage device so that data samples acquired during a next period of time can be temporarily stored.

Abstract
Techniques are described for assessing road traffic conditions in various ways based on obtained traffic-related data, such as data samples from vehicles and other mobile data sources traveling on the roads, as well as in some situations data from one or more other sources (such as physical sensors near to or embedded in the roads). The assessment of road traffic conditions based on obtained data samples may include various filtering and/or conditioning of the data samples, and various inferences and probabilistic determinations of traffic-related characteristics of interest from the data samples. In some situations, at least some of the mobile data sources are configured to frequently acquire and store data samples, and to occasionally make multiple such data samples available together for use in the road traffic condition assessment (e.g., by acquiring a data sample every minute and by transmitting a group of stored data samples every 15 minutes).

11. A method for a device in a vehicle to automatically provide information regarding travel of the vehicle on one or more roads, the method comprising, under control of the device:
-
obtaining multiple data samples that are each acquired at a distinct acquisition time to report a geographic location and travel characteristics of the vehicle at that acquisition time;
storing the multiple data samples until one or more predefined conditions are satisfied; and
after the one or more predefined conditions are satisfied, automatically providing the multiple data samples in a single data transmission to a traffic information system configured to use data samples provided from multiple vehicles for facilitating travel on roads. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

59. A computing device configured to provide information regarding travel of a vehicle on one or more roads, comprising:
-
one or more storage components; and
a data source information provision component that is configured to provide information regarding travel of a vehicle on one or more roads by obtaining multiple data samples at multiple distinct acquisition times such that each data sample reflects one or more travel characteristics of the vehicle at the acquisition time for the data sample, by temporarily storing the multiple obtained data samples in the one or more storage components, and by sending the multiple stored data samples as a group for use by a remote traffic information system in facilitating travel on one or more roads. - View Dependent Claims (60, 61, 62, 63, 64)
