Experimental Development and Testing of a Smartphone Eco-driving App

Aggressive driving is responsible for a significant share of vehicle emissions. This paper attempted to develop and test an experimental warning device, called the eco-driving APP, which provided warnings to drivers to mitigate aggressive driving behaviors, thus reducing vehicle emissions. To this end, the eco-driving APP was developed in a smartphone with the Android platform, which provided real time warnings to drivers on their driving behaviors that were out of the threshold range, which was defined based on the concept of Vehicle Specific Power (VSP) distributions. It was then evaluated by collecting the instantaneous driving activity and the associated emissions data of a test vehicle equipped with a portable emission measurement system (PEMS) embedded with an on-board Global Positioning System (GPS) logging device, which recorded the vehicle’s instantaneous position and speed, and the associate emissions. Data gathered during the test by PEMS were used to analyze the VSP distributions and emissions. The driver of the test vehicle was provided warnings by the eco-driving APP while driving. It was shown from the study that with the warnings provided by the eco-driving APP, most of emissions, except for HC in one circumstance, were reduced substantially. In most circumstances, driving behaviors shifted to the driving patterns, which led to reductions in vehicle emissions.
