I disagree. What advantage would video provide over magnetic strips? Magnetic strips are (likely): - Cheaper than setting up and powering video cameras - Resistent to harsh conditions (eg. good luck hiring someone to go around town and wiping all the foggy camera lenses during a rainstorm) - Likely to last longer than a video sensor - Probably more accurate than video, too - Doesn't need a huge computing infrastructure to monitor and interpret - Respects pedestrians' privacy more
