Definition of Key Performance Indicators for energy efficient assessment in the transport sector

The transport sector is constantly growing as well as its complexity and energy consumption. One way to reduce the involvement and the volume of data to evaluate and monitor the energy efficiency of the sector for cities authorities is by using Key Performance Indicators (KPIs). This paper describes a set of KPIs to measure and track energy efficiency in the transport sector. The KPIs that are summarized in this paper were identified based on a literature review of mobility projects/strategies/policies that had been implemented in cities around the world. Future applications, which are presented at the end of this article, will give a better understanding of the systems and its components.
