Abstract: A system for managing vehicular traffic on a roadway includes a sensing unit positioned within a vehicle traveling on the roadway. The sensing unit is configured to determine occupancy data based on the number of passengers within the vehicle. An ambient light sensor is operatively associated with the sensing unit such that upon sensing an intensity of ambient light, an adjustment is made to the system to aid in the determination of occupancy data. The occupancy data is configured to be communicated to one or more receiving units positioned above or proximate the roadway.
