This report describes existing and emerging exposure data sources for highway safety analysis. Existing exposure data sources reviewed include: Highway Performance Monitoring System (HPMS), Highway Safety Information System (HSIS), Long-Term Pavement Performance (LTPP) Monitoring System, Nationwide Personal Transportation Survey (NPTS), National Truck Trip Information Survey (NTTIS), Operational Exposure Data Sources, Residential Transportation Energy Consumption Survey, Truck Inventory and Use Survey (TIUS), and Weight-in-Motion (WIM) devices. Emerging data sources are new sources or existing sources that have not been traditionally used to derive exposure estimates. Three areas were reviewed for possible emerging exposure data: Intelligent Transportation Systems (ITS), transportation planning surveys, and traffic volume data collected by the States. One-page summaries are provided for each exposure data source. A longer description covers the purpose of the collection, contents, period covered, sample design, data collection methods, sample sixe, data quality, data format, possible cautions in using the exposure data, and availability of the data.
