Description:
The New York State Department of Transportation developed highway performance measures for crash analyses at the Hudson Valley Transportation Management Center (HVTMC). This tool includes performance measures and methodologies for reporting crash totals and severities along corridors, comparing historical average crash rates to recent crash rates, and identifying secondary crashes to determine areas of improvement for HVTMC operations and incident management strategies. Criteria were also developed for performing network screening, which has driven the development of weekly and monthly real-time crash reports using crash record, physical roadway characteristic, weather, incident, and traffic volume databases.
Various performance measures can be incorporated in the tool for network screening, including advanced methods that account for regression-to-the-mean and the non-linear effect of traffic volume. This requires the user to input, compute, or link to the desired performance measures.
QlikView® was used to develop analysis and reporting web interfaces that allow for on-demand reports. QlikView® is a commercially available business intelligence program that facilitates data mining and pattern/trend identification utilizing a web browser. Analysis can also be automated to investigate crash data for trends in crash history, types of crashes, crash costs, network screening, and other statistics.
