******************************************

Over-roadway sensors include video image processors, which use cameras mounted on tall poles adjacent to the roadway or on traffic signal mast arms over the road; microwave radar, laser radar, ultrasonic, and passive infrared sensors installed either alongside or above the road; and acoustic sensors ...The over-roadway laser radar sensor transmits energy in the near infrared spectrum, which is just above the visible wavelength spectrum. An advantage of laser radar is that it transmits multiple beams for accurate measurement of vehicle position, speed, and class.
