Abstract
Climate change has emerged as a very important threat to economic development, atmosphere, and public health. One of the driving factors for global climate change was road transportation. therefore, this sector needs a responsibility of reducing its effect on the environment. this study finds ways to mitigate climate change impacts on environment especially greenhouse gas emissions and other selected air pollutants by anew navigation concept called eco route by applying a 3D Eco -Routing Model to reduce the environmental footprints of road transports in Addis Ababa city for distribution vehicles. The applied model in this study considered the road gradient, varying velocity or speed of vehicles, and weight of vehicles to evaluate gradient effects on consumption of fuel, CO 2 and also other air pollutants emission, the model is applied in three scenarios within different vehicle weight range and three different cases in the city of Addis Ababa, political capital of Africa, The attained results imply eco-routes emission Reduction potentials up to 39.81% from fuel and CO 2 and 25.65% from other air pollutant in the tested scenarios. The results showed that Eco Routes have the ability of reducing Fuel consumption, CO 2 and other air pollutant emission rate. Such potentials of eco routes make them an ecological solution for a future sustainable transportation in Addis Ababa City. This study recommends the use of Eco Routes, rather than Fastest and Shortest Routes, where significant road gradients exist.
