The National Renewable Energy Laboratory's Open Platform for Agile Trip Heuristics (NREL OpenPATH, accessible at https://nrel.gov/openpath) revolutionizes the way individuals and communities track and analyze their travel behaviors. This innovative app allows users to monitor their travel modes, including car, bus, bike, and walking, and measure the corresponding energy consumption and carbon emissions.
NREL OpenPATH empowers users and communities to gain a deep understanding of their travel choices and patterns. It facilitates experimentation with different modes to enhance sustainability and provides valuable data for evaluating outcomes. Such insights are crucial for shaping effective transportation policies and planning, ultimately contributing to the development of more sustainable and accessible urban environments.
The application offers personalized feedback to users on the environmental impact of their travel decisions. Additionally, it aggregates community-level data on mode shares, trip frequencies, and carbon footprints, which is made available through a public dashboard. This feature enhances transparency and fosters community engagement in sustainable transport initiatives.
NREL OpenPATH is designed with an open architecture, ensuring transparent data collection and analysis. It supports continuous data gathering and processing through a smartphone app, backed by a robust server and automated data processing system. This flexibility allows the platform to be tailored for specific programs or research studies.
Upon installation, the app does not immediately start collecting or transmitting data. Users must actively join a study or program by clicking a link or scanning a QR code, at which point they are prompted to consent to data collection and storage. For those not affiliated with a partner community or program but interested in tracking their personal carbon footprint, there is an option to participate in NREL's open-access study. Data from such participants may serve as a control group for experiments conducted by NREL's partners.
At its core, NREL OpenPATH functions as an automatically sensed travel diary, utilizing background location and accelerometer data to construct a detailed record of travel activities. Users have the ability to add semantic labels to this diary, as required by program administrators or researchers, enhancing the data's utility.
It's important to note that continuous GPS use in the background can significantly reduce battery life. To mitigate this, the app automatically deactivates GPS when the user is stationary, resulting in minimal battery drain of approximately 5% for up to three hours of daily travel.
