    Applying 3D-Eco Routing Model to Reduce Environmental Footprint of Road Transports in Addis Ababa city.
    (2019-10) Seifu, Woldemichael; Daniel, Alemayehu (PhD)
    Road Transportation is the fastest growing major contributor to global climate change, accounting for a significant share of worldwide energy-related carbon dioxide CO2 emissions. It is therefore, this sector needs to undertake responsibilities for its environmental impact. This paper introduces a 3D Eco -Routing Model to reduce environmental footprints of road transports in Addis Ababa city for distribution vehicles, which adds one more degree of freedom to the system and allows driving routes to be optimized for minimum fuel consumption. The applied model in this study takes into account the effects of road inclination, varying velocity, and vehicle weight to evaluate the effects of road inclination on a vehicles fuel consumption and its proportional CO2 - Emissions, the 3D -Routing-Model is applied in three different scenarios within different vehicle weight range in the city of Addis Ababa, political capital of Africa, The obtained results indicate that eco-routes can yield significant fuel and CO2 Reduction potentials of up to 39.818% in the tested scenarios in addition from other pollutants eco routes saves emissions up to 25.650% in the tested scenarios. These numbers designate the importance of considering the topographic characteristics and fuel consumption in routing applications to reduce vehicles emission impacts on the environment. These findings have implications for future investment and policy decisions to concern eco routing strategies.
