Abstract

ALVARENGA-RODRIGUEZ, José Mauricio. A comparative study on speed and density in macroscopic models of vehicular traffic adding the spatial variable on speed. Rev. Mat [online]. 2021, vol.28, n.1, pp.125-142. ISSN 1409-2433.  http://dx.doi.org/10.15517/rmta.v28i1.41890.

The present work aims to compare the classic relations between density and speed in the context of continuous models of vehicular traffic, integrating a linear dependence of the spatial variable. Database from NGSIM was used in order to accomplish such task, specifically that belonging to I-80 highway. Furthermore, to make a balanced comparison, the parameters of the classical relations were also estimated without the linear modification of the spatial variable.
