Northern Virginia CAD2CAD Exchange

Four jurisdictions in Virginia (Alexandria, Arlington County, Fairfax, and Fairfax County) sharing emergency equipment since the 1970s previously determined "closest unit" availability by a series of phone calls between dispatch centers. Using the Northern Virginia CAD2CAD Exchange to connect disparate computer-aided dispatch (CAD) systems using NIEM, Safecom, and an RMS message set has cut response time in half.
