The city and its behavior in the transfer of heat, generates lines of research that study phenomena such as the Island of Urban Heat (ICU); Within its formation factors, the heat expelled by the vehicle is the least analyzed in the literature. Thanks to the Computational Fluid Dynamics (CFD) software and its validation with measurements in the field, data is acquired to examine the thermal behavior in an urban canyon based on the number of cars passing through it and the heat expelled by its engines, the speed of the wind and orientation. The results show that the temperature increases between 26% to 10% more, and the highest values are in the simulated cases with a north-south orientation, affecting the passer-by as to the energy efficiency of the buildings.
