Optimal speed advisory: a vehicular networks application focused on decreasing CO2 emissions
(IEEE Latin America Transactions, 2016-08-29) Orozco, Oscar Arley
Whilst the number of vehicles moving through the streets growths exponentially, the high density vehicular flow is now a mobility and a public health problem for governmental institutions and people, since the time of travel, gasoline consumption, and greenhouse gas (GHG) emissions have suffered an important increase. Hereby, several research projects aim to reduce the impact of this increase using new technological platforms like the so-called Vehicular Networks (VN), which are focused on the establishment of wireless connections between automobiles and/or fixed infrastructure. In this context, and aiming to reduce the potential carbon footprint of the vehicles, we have developed an application for the simulation of a VN using two software applications: SUMO and OMNeT++. The application we developed sends information packets directly to the cars about the adequate speed in a given area, optimizing the fuel usage and reducing the GHG emissions. Results show that when vehicles follow the speed (previously studied), the gasoline consumption and the GHG emissions present a considerable decrease compared to the vehicles not running at that speed.
OSA : a vanet application focused on fuel saving and reduction of CO2 emissions
(Universidad Icesi, 2014-04-01) Orozco, Oscar Arley; Llano Ramírez, Gonzalo
Con el aumento en el número de vehículos en las carreteras, el elevado flujo vehicular se ha convertido en un problema de movilidad y de salud pública para las instituciones gubernamentales y para las personas; ya que el tiempo de viaje, la gasolina consumida y las emisiones de Gases de Efecto Invernadero [GEI] han aumentado considerablemente. Por esto se requieren políticas, medidas y acciones para disminuir el impacto que está teniendo dicho incremento. Bajo este contexto, se ha desarrollado una aplicación para redes vehiculares en los simuladores SUMO y OMNeT++ que optimiza el consumo de gasolina y disminuye las emisiones de GEI, demostrando que si los vehículos respetan una velocidad preestablecida y estudiada anteriormente, el consumo de gasolina y las emisiones de GEI disminuyen considerablemente en comparación a los vehículos que no siguen dicha velocidad.
OSA: A VANET application focused in energy efficiency

With the growth in the number of vehicles moving through the streets, high vehicular flow has become a mobility and public health problem for governmental institutions and people since time of travel, gasoline consumption, and greenhouse gas [GHG] emissions have suffered an important increase. Hereby, policies and actions are required to reduce the impact of this increase. In this context, we have developed an application for the simulation of Vehicular Ad hoc Networks [VANET] using two software applications: SUMO and OMNeT++. The application we developed optimizes fuel usage and reduces GHG emissions; showing that vehicles following a preset speed (previously studied), gasoline consumption and GHG emissions present a considerable decrease compared to vehicles not running at that speed. © 2014 IEEE.
