Interactive Mapping Portal for Analysis and Crash Tracking (IMPACT) Homepage Engage with crash related data through easy-to-understand pre-built reports, interactive dashboards, or conduct your own self-driven analysis. IMPACT provides several means of engaging with the crash data including: Interactive Data Dashboards: Pre-built dashboards use maps, charts, and tables to describe data. Allows for interactive analysis and data exploration specific to a given data theme in a range of categories. Data Query and Visualization: Conduct data queries to generate subsets of the crash data. This may be done at the crash level, the vehicle level, or the person level. You can then visualize the data in three core ways: on charts, on tables, or spatially on a map. Data Extraction: Extract publicly available data by municipality and date range. Also, a link is provided to MassDOT’s Open Data Portal for more large-scale data download capabilities. Reports: IMPACT provides a suite of pre-built reports for access to cleanly organized information across a spectrum of categories. Crash Tabulation & Charting: Tool to aggregate selected data in a matrix to display two or more variables. The crosstab provides summary data and can be used to summarize the full crash database as well as subsets of the data, based on the user selected variables. https://apps.impact.dot.state.ma.us/cdp/home

This grouping of dashboards provides information on general crash statistics at the crash level.
