About this dataset

Mile markers for select Boulder County roads and CDOT roads. The Boulder County roads were initially selected based on historic precedent, referencing printed maps in the Public Works (formerly Transportation) Department. Markers for more roads may be added after further review. Historic roads included some within municipalities, and mile markers were retained for those roads, regardless of annexations. Mile marker points along County roads were measured using GIS. Each road length was calculated using GIS, depending on accuracy from the Colorado StatePlane coordinate system and then accounting for slope from a 2.5 foot DEM. Markers, every quarter mile, were located along routes using a linear referencing method. Markers on CDOT roads were selected from a feature service owned by them. The selected roads were based on the Road_Map_Roads feature class. Note: Road Maintenance mile posts will be move based on markers in this dataset.

Crashes Historic

Boulder County crashes mapped from CDOT data. The crash records have a variety of location information, so multiple methods were used to geolocate them, from using lat/long on CDOT roads to geocoding based on the 'loc_x" fields. The CDOT data is intact, except where street names were cleaned up for geocoding matches and city names were fixed. Then, summary information, intersection identification and corridor identification were added. The records include all crashes potentially going back to 1986 that were received from CDOT, and were mappable. This does not account for all crashes during that time period. Due to structural data changes (schema changes), this dataset contains historic crash information from 1999 thru the end of 2020. Crash data going forward will be in a new feature class named “Crashes”.

Crashes

Boulder County crashes mapped from CDOT data. The crash records have a variety of location information, so multiple methods were used to geolocate them, from using lat/long on CDOT roads to geocoding based on the 'Location_x" fields. The records include all mappable crashes starting from January 1, 2021 and ongoing. Hence, this dataset does not include all crash data received from CDOT. Further, historic crash data can be found in the dataset named “Crashes_Historic”.
