Abstract
A traffic flow measuring apparatus includes a processor configured to judge a size of a vehicle, depending on a detection frequency or a non-detection frequency of a reflected wave from the vehicle with respect to a transmission wave transmitted from a radar apparatus, within a detection time of the reflected wave from the vehicle, set according to the detection of the reflected wave.
