Description: “HCL_N15 contains sections of Maine’s public roads (between intersections and/or town boundaries) determined to be High Crash Locations (HCLs). These HCLs are link locations where the critical rate factor (CRF) is at least 1.00 and at least 8 crashes occurred within the 3 year time period including the specified year and the two years prior. HCL_N15 created by Maine Department of Transportation using CAS (Crash Analysis System) and query in TIDE.Note regarding 2011 data: During the 2011 calendar year, the Maine Department of Public Safety in cooperation with the Maine Department of Transportation and other agencies instituted a new crash report format. Crash records for 2011 and 2012 werereviewed for missing reportsthis was resolved for the most part and the HCL listing was re-run. We continue to monitorongoing police department crash report submission activity.That effort has had a positive impact.Note regarding usage: These locations, together with the HCL link locations, are traditionally used in identifying and prioritizing capital safety projects on a statewide basis, but do not reflect all locations with opportunities for safety improvement. Likewise, not all HCLs reflect locations where infrastructure improvements would result in increased safety. Users are encouraged to use the most current data sources when conducting any localized or regional analysis. This data was created by Maine Department of Transportation using data from the Crash Analysis System (CAS) accessed through the MaineDOT data warehouse known as TIDE.
