TRAFFIC FLOW RATES
First Claim
1. A system for determining a flow rate of traffic for a road segment, comprising:
- a traffic modeling component, implemented via a processor, configured to;
determine probe flow rate information based upon locational information from one or more probe vehicles on a road segment;
obtain satellite imagery of the road segment;
analyze the satellite imagery to identify a count of vehicles on the road segment for a unit of time; and
determine a flow rate based upon the probe flow rate information and the count of vehicles for the unit of time.

Abstract
One or more techniques and/or systems are provided for determining a scaled flow rate of traffic for a road segment. For example, probe flow rate information is determined based upon locational information from one or more probe vehicles on a road segment (e.g., a flow rate of probe vehicles corresponding to a sum of probe vehicles identified from time stamped global positioning system coordinates provided by the probe vehicles). Satellite imagery of the road segment is analyzed to identify a count of vehicles on the road segment. Scale factor and offset information is estimated based upon the probe flow rate information and the count of vehicles. The scale factor and offset information is used to scale the probe flow rate information to determine a scaled flow rate that may be a relatively accurate flow rate of traffic, which may correspond to an inferred traffic volume along the road segment.
