Modelos de velocidad en calles urbanas previo a intersecciones no semaforizadas

Abstract

In urban streets is preferable that low operating speeds exist to provide security to its users. However, generally these speeds may be greater than the speed of design. To know the operation speeds is necessary to measure them or get them through equations. These equations still have not been calibrated in the country. For this reason, this thesis had as purpose developed models of speed in urban straight streets previous intersections without semaphores. For that reason, it was collected speed data form 45 drivers, in 13 study section placed in the urban part of the city of Loja, Ecuador, with the use of the Garmin Dash Cam 20 equipment. It was analyzed the influence of independent variables corresponding to the geometrical characteristics of the street, street environment, driver and car over the speed. It was developed models of prediction of speed, acceleration and deceleration fort urban straights streets regulated with the sign stop. The length of the straight was the variable statistically more significance over the speed. The obtained models will serve to reduce the difference between the design and operation speed during the design of the urban street.
