Because NMVCCS investigators were at the scene with emergency responders, the database contains crash contributing factors and driver behavior data not in any other database.
Figure 9 shows the critical reason coded by the NMVCCS investigator in intersection crashes (SCP, LTAP/OD, and LTAP/LD) compared to all other crashes in NMVCCS.
Also unique to NMVCCS is a determination of which vehicle had the right of way.
Age Goup of Drivers that Had Right of Way and did not have Right of Way in SCP, LTAP/OD, and LTAP/LD Intersection Crashes from the NMVCCS Database.
Police Reported Alcohol Involvement for Drivers that Had Right of Way and did not have Right of Way in SCP, LTAP/OD, and LTAP/LD Intersection Crashes from the NMVCCS Database.
Although time consuming, some of these road geometry values could be extracted from the scene diagrams prepared by the crash investigators in the NASS/CDS and NMVCCS databases.
Another limitation of the NMVCCS database was that the data were collected prior to the proliferation of cellphone use in the U.
In NMVCCS value 2 or 3 for the variable "reljnct" were identified as intersection crashes.
The NMVCCS investigators also code Collision Deformation Classification (CDC) for vehicles involved in collisions.
