GONZALEZ-PEREZ, Mario Guadalupe. Entropy and negentropy of private electric vehicles in urban systems: homeostasis of mobility in Mexico. Dyna rev.fac.nac.minas [online]. 2018, vol.85, n.206, pp.171-177. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v85n206.72509.

Since many years ago, private electric vehicles threaten to interact massively and substitute a large proportion of internal combustion vehicles; nevertheless, the homeostasis of the speed and the elapsed time in domestic journeys fluctuate between the phases critical and sub-critical due to the entropy of the production and consumption processes that pressure urban mobility subsystems and vice versa. This work considers from the Systems Theory the interaction of the entropic components of Mexican urban mobility through the model entropy-homeostasis-negentropy, which is an adaptation of the model pressure-status-response, issued by the Organization for Economic Cooperation and Development with the intention of showing qualitatively which is the most probable scenario of the private electric vehicle for urban mobility. The results show that a larger number of vehicles produce a higher intra-systemic entropy. Thus, it is essential to implement definitive negentropies to favour electric mobility.
