An apparatus and method for monitoring mixed pedestrian and motor vehicle traffic. The apparatus include an optical camera, an infrared camera, and a wireless-device counter, each obtaining complementary information regarding the crowd density and flow of the traffic. Performing heat signature analysis and blob detection of the infrared image data to discriminate pedestrians from motor vehicles. Performing optical flow computations with Gaussian pyramids, Histogram of Oriented Gradients calculations, support vector machine (SVM) classifications, and correlation-based clustering using the optical images to determine the crowd density and flow of pedestrians. Incorporating the (SVM) classifications with the blob detection to differentiate pedestrians from motor vehicles. Obtaining an estimate of the number of wireless devices using the wireless-device counter as an additional indicator of the number of pedestrians and motor-vehicles. Finally, combining the above-identified regarding the crowd density and flow to create an improved traffic estimate. |

1. A traffic-monitoring controller, comprising:
an interface configured to receive optical-image data and device-count data; and processing circuitry configured to
obtain, using the interface, the optical-image data representing an optical image of the first area,obtain, using the interface, the device-count data representing device-identification information corresponding to wireless devices detected by a receiver, wherein the detected wireless devices are within a second area corresponding to an area within a wireless communication range of the receiver, and the device-count data further represents time information corresponding to when the wireless devices were respectively detected,determine, using the optical-image data, a first pedestrian estimate indicating a number of pedestrians in the first area,determine, using the device-count data, a pedestrian-and-motor-vehicle estimate indicating a number of pedestrians and motor vehicles in the second area, anddetermine, using the first pedestrian estimate and the pedestrian-and-motor-vehicle estimate, a first motor-vehicle estimate of a number of motor vehicles in the first area, whereinthe second area overlaps the first area. |
