Abstract: The invention relates to a method and a device for determining the speed s/.delta.t) of vehicles, in which with the aid of at least two sensors (1, 2, 27, 28) spaced apart from one another (distance s), the time .delta.t=t.sub.1 -t.sub.2 required to drive over both sensors (1, 2, 27, 28) is ascertained. The object of the invention is to disclose a speed measuring method that is simple to accomplish, with which accurate measurement values are ascertainable, and in which external factors of the pavement can largely be ignored. This is attained essentially by using induction loops, instead of the usual piezoresistive pressure sensors, as the measurement sensors (1, 2, 27, 28).
