Report DateReportDateMPD Crash DatabaseDate crash was reported.
Route IDRouteIDLRS Core Segmentation

RouteID of the route the accident occurred on.

If "Route Not Found", this likely means that the crash point was too far away from the DDOT GIS centerline.  If a given crash point is 50 meters or more from a centerline, the crash cannot conclusively be linked to a particular roadway/centerline.

Check "Location Errors" for more detail about any other issues

Error routing crash to centerlineLocationErrorMaster Address Repository (MAR)

Error messages describing why the crash point was not linked to one or more centerline network assets.

Crash point too far from centerline (>50m):  The crashpoint cannot be linked to a nearby DDOT LRS centerline (greater than 50 meters).

BlockKey ERROR:  The Roadway Blockkey did not match DDOT's current inventory of LRS Blockkey. 

SubBlockKey ERROR:  The Roadway SubBlockkey did not match DDOT's current inventory of LRS Subblock. 

ERROR on getOnBlockPointInfo:  There has been an issue with querying DDOT's network matching tool

ERRORS on getNearestBlockIntersection:  There has been an issue with querying DDOT's nearest intersection match tool

Intersecting Route ERROR.  The intersecting route name/id provided does not match up to a DDOT LRS Route.

Blockkey ERROR. {} Not Found on Corridor:  The Roadway Blockkey provided does not match up to a DDOT's inventory LRS Corridors.  Could be an issue with corridor data, block data, or DDOT's network matching tool.
