Urban transport: Comparative study of energy efficiency between taxi drivers in Salvador city, Bahia - Brazil

Abstract

The objective of this work is to evaluate and quantify the potential of CO2 mitigation in the transportation of passengers, in the use of sub modal urban taxis in the city of Salvador. The complexity and behavior of society influence the behavior of taxi services that are concessions, population increase and consumption. Measures and technologies: (a) the reduction of fuel consumption, as well as (b) the gradual replacement of low-CO2 fuels can contribute to improving the relations of society and the environment. Continued use of fossil fuels is proven to increase the planet’s temperature. The methodology used follows the theoretical reference Lee Schipper. The main parameters used to measure emissions relate to the distance traveled, the number of passengers and fuel consumption. Data collection was through a secondary source and primary source, using semi-structured questionnaires at four taxi points through accidental sampling. The hypothesis is that the increase of 0.5 km/l in the energy efficiency of taxis using ethanol instead of CNG could reduce CO2 emissions by about 20%.
