Abstract: A method of vehicle detection is provided. The method comprises receiving an image from a traffic camera, wherein the image contains vehicle traffic flow. A number of regions in the image that exceed a predetermined number of candelas are identified and masked. Contrast edges are added around the masked regions in the image. One or more vehicles are detected in the image based on the contrast edges.

Abstract: A method of managing traffic flow. The method includes receiving, at a camera, an image containing vehicle traffic flow. The method also includes processing, using a processor, the image to mask areas in the image that exceed a predetermined number of candelas. The method also includes thereafter analyzing, using the processor, the image to determine a parameter related to the vehicles, whereby an analysis is performed. The method also includes managing the traffic flow based on the analysis.

Abstract: An apparatus for integrating sensors with a traffic signal. A camera is operably disposed within a housing. The housing is attached to an object such that the camera can observe traffic flowing past a traffic signal. A visor is attached to the housing such that an optical aperture of the camera is covered by the visor, wherein the visor comprises a roof having an angle that slopes, relative to the housing, towards the optical aperture, wherein the visor further comprises a floor connected to the roof, and wherein the floor extends outwardly from the housing.

Abstract: A traffic signal including a housing, a light source disposed within the housing, and a door operably attached to the housing. The door is configured such that photons generated by the light source may be sensed outside the housing. The traffic signal also includes a sensor attached to one of the door and the housing.

Abstract: A traffic signal with integrated sensors. The present invention provides an apparatus for integrating sensors with a traffic signal. A signal case has a housing and a light source placed within the housing. A door attached to the housing is configured such that photons generated by the light may be sensed outside the housing. A tab is attached to the door. A sensor is attached to the tab. The housing or the door is adapted to allow the sensor to sense a parameter originating from outside the housing.
