High-resolution global geopositioning system for last-mile delivery

Abstract

High-resolution monitoring systems are commonly used to calculate mechanical and energy performance, as well as environmental impact resulting from the operation of a fleet of vehicles in a region. These systems require recording operational or vehicle position data, energy consumption in the case of electric or electric-assisted vehicles, and buttons for specific signals in the operation, such as the start of operation, end of operation, or package delivery. Some vehicle tracking devices available on the market do not allow speed and energy consumption data to be recorded and accessed at the required sampling frequency. This study presents the development and validation of a remote sensing device to record energy consumption and operational variables of a vehicle under real operating conditions with a frequency of 1 Hz. The functioning of the device, the integrated elements in its development, and the data analysis process are detailed. Finally, using the monitoring equipment data, a comparison was made between the operation of electric vehicles and internal combustion vehicles, achieving savings of up to 83% in operating costs and a 79% reduction in CO2 emissions.
