The speed profile describes the speed along the highways. To develop it, models that correlate the speed with the road geometry are needed. Those models consider that operating speed is constant along the horizontal curves. Also, the models do not consider the effect of the entrance tangent on speed, neither the speed variability into the curve. This paper proposes new speed profile models based on speed measurements obtained with a GPS device. The models show that the speed negotiation occurs at the entrance tangent and not in the middle point of the curves as shows the traditional models. The curve length do not permits to drivers adjust speed.Los perfiles de velocidad permiten describir la velocidad de una carretera a lo largo de su traz...
