Systems offer alternative solutions to traffic congestion.
The system can identify vehicles using a small radio frequency transponder that is mounted underneath the front bumper of the vehicle, and each user has a unique account that is automatically debited during every transaction. Polarimetry observations via radio telescope antennae are superimposed onto the contour intensity maps using directional lines that indicate the angle of polarization as well as the percent of the emission that is polarized by the length of the lines.
