Data Fusion for Nonmotorized Safety Analysis (03-049)

Project Description: This project explored an emerging research territory, fusion of nonmotorized traffic data for estimating reliable and robust exposure measures. The researchers developed fusion mechanisms to combine five bike demand data sources in Austin and demonstrated the applicability of the fused estimate in two crash analyses. The data used in this study were gathered from five primary data sources: (a) actual bicycle volume counts, (b) bicycle-sharing data, (c) NHTS add-on data, (d) Strava data, and (e) StreetLight data. In addition, the sociodemographic and land-use data for building models were obtained from the American Community Survey, Austin Transportation Department, and other public data domains. Data Scope: Please see document below for additional information (filename: 03-049_Metadata ). Data Specification: Some of the datasets used in this project were obtained through public domains, and thus are available for sharing. Some other datasets were requested from corresponding data providers or government agencies and obtained under specific data use agreements, and thus are not available directly from the authors.
