1. An apparatus for generating traffic information, comprising:

  • a first information collection unit for collecting first sensed data, including first reference sampled data related to detection of information about a vehicle and a plurality of pieces of first surrounding sampled data obtained before and after the first reference sampled data, from a first sensor unit that samples variations in geomagnetism at a first point of a traffic lane at predetermined intervals;

    a second information collection unit for collecting second sensed data, including second reference sampled data related to detection of information about the vehicle and a plurality of pieces of second surrounding sampled data obtained before and after the second reference sampled data, from a second sensor unit that samples variations in geomagnetism at a second point of the traffic lane at predetermined intervals;

    a comparison and analysis unit for determining similarity between the first sensed data and the second sensed data by comparing them with each other, extracting a first time at which the vehicle passed the first sensor unit from the first sensed data, and extracting a second time at which the vehicle passed the second sensor unit, corresponding to the first time, from the second sensed data; and

    a computation unit for calculating the vehicle'"'"'s average speed using information about the first time and the second time.
