The effects of an acceleration advisory tool in vehicles for reduced fuel consumption and emissions

This study evaluates whether the use of an acceleration advisor leads to fuel savings, to determine the change in traffic-related emissions and to analyse changes in driving patterns on various routes. The acceleration advisor provides advice to drivers through resistance in the accelerator pedal when they try to accelerate rapidly. In a test carried out in Southern Sweden, the acceleration advisor was installed in four postal delivery vehicles. The driving pattern parameters show that strong acceleration was significantly reduced, which indicated that the drivers had complied with the advisor. On two of the three routes, the acceleration advisor had a positive effect on emissions. In general, no significant reduction in fuel consumption was observed when driving with the acceleration advisor activated.
