System and method for measuring the real traffic flow of an area

摘要

A system and method for measuring a real traffic flow of an area use images of vehicles and pedestrians taken from the sky in time intervals of an area. The system and method also use continuous tracking data for vehicles and pedestrians, provided by navigator manufacturers, map providers, route applications or by phone carriers. Both images and continuous tracking data are combined and processed by a processor that applies image pattern recognition software to the images so that each vehicle and pedestrian in the images is recognized and labeled for which tracking data is available. The system identifies vehicles and pedestrians contained in both databases and applies a weight to thereto. Accordingly, the system and method are able to estimate the traffic flow and the total number of vehicles and pedestrians for a particular time and area.

主权项

1. A system for measuring a real traffic flow of an area, the system comprising:
images taken from a sky in time intervals of an area; continuous tracking data for a probe that is collected and provided by navigator manufacturers, map providers, route applications or by phone carriers that record cell towers, traffic counts, router connections, near-field-communication devices, and beacons that are able to geolocate the probe; the continuous tracking data comprising at least a longitude, latitude for each time unit for which the probe is tracked; a database of universe of elements that comprises the images; a continuous database that comprises the continuous tracking data; and a computer processor configured to:
apply image pattern recognition software to the images taken from the sky so that each element comprised in the images is recognized, labeled and at least a latitude, longitude, time, speed and type of vehicle or number of pedestrians is calculated;allocate to each probe the continuous tracking data for which the longitude, latitude and time match;calculate a ratio between a number of elements recognized in the images and a number of probes for which the longitude, latitude and time match; andestimate the flow and the total number of elements within an area by applying the calculated ratio to the continuous tracking data for a particular time for which an image from the sky is not available.
