I know these are for gathering traffic flow facts but in selective: Many times you see 1 cord, other times you see 2. Is 1 for only counting the cars? Is the 2 cords for speed information and count? Doesn't seem close to speed data could be derived from one severely acturately. Anything else I haven't mentioned?
Answers: The chords are rubberised switches that connect to a data-logger, one chord measures traffic numbers for flow data , two chords measures speed (maybe to determine if they will put up a speed camera). if they singular want it in one direction after it will only stir half means of access across the road.
actually if you be to have two cords near a given distance you could calculate the speed of the cars but that information would really not do much honourable. mu guess is that they are for two separate peoples or for redundancy.
