Road conditions and driving patterns on fuel usage: Lessons from an emerging economy

Abstract

Given its usage in freight and urban transportation, diesel supply is a major global issue. Diesel dependence and the urgency of the energy transition are normally addressed on the supply side by either expanding oil refineries or evaluating alternative fuels. Here we focus on the demand-side by examining how road pavement conditions and eco-driving practices affect diesel fuel consumption on highways. This can be particularly important in emerging countries, where road pavement is normally not well-managed and conserved. This analysis encompasses six scenarios for Brazil that vary in road conditions, driving cycles, and tire inflation states. Findings show a significant potential for annual diesel savings, reaching 4.52 billion liters, or 16% of fuel efficiency. A financial analysis indicates a positive return by the year 2037. Hence, this study emphasizes the need for a multidimensional approach to reduce fuel consumption and enhance environmental sustainability within the transportation sector of an emerging economy. While infrastructural improvements are crucial, their effectiveness is greatly amplified when paired with efforts in driver education.
