As part of a Federal Highway Administration's Exploratory Advanced Research (EAR) Program, the Office of Highway Policy Information led a research initiative focusing on the feasibility of estimating high-quality passenger and truck travel origin-destination (OD) data from mobile device data. The undertaking has significant implications for State DOT, MPO, and Federal programs as OD data drives decision makings. The objective of the effort is to provide transparency to big data application and data methods, improve results interpretability, and enable the community to continue to explore the subject and improve the overall technology development and deployment.
A detailed technical document covering all key issues and methods and approaches used to resolve various issues is provided. The main objective of this methodology document is to provide transparency on various technical issues. The goal is to enable users of the data and methods to understand how products are produced. Also, it will offer an efficient starting point for these who would like to continue such research to make the process more efficient and more appropriate
The software codes developed to analyze the input data and generate output data are provided here. The goal of releasing the software code is to enable researchers and practitioners to adopt, modify, and improve the codes as they see fit for their application vs. starting from scratch.

As part of the ERA research effort, a set of irreversibly modified passive data is developed to offer researchers in the community access to input data. It is common knowledge that the lack of access to passive data limits research activities. This sandbox approach is a compromise between protecting privacy and data access needs. The goal of providing the sandbox is to enable more researches are being carried out.
As this project is a completed R&D effort, the Office of Highway Policy Information will not be able to provide all the technical support you may need while you are exploring the topic. However, the office appreciates your notification and the sharing of any further progress you may have made.
