Phase 1 Accomplishments PSAPs VTA 7, SB 4 Analyzed 232 sectors for 5 WSPs Built online system Post cutover analysis
Phase 1 Sector Analysis Considered sectors where >50% of calls originated off -highway In Ventura County of the 232 sectors considered for reassignment / cut-over 223 (96%) were approved by PSAPs & County Coordinator CHP approved 92 (39%) for reassignment / cut-over Of 120 sectors previously deployed to local agencies none met CHPs criteria to cut to CHP
CHP Cut-over Criteria If 85% or > of the calls plot in the local PSAPs jurisdiction then the sector can route to the local PSAP If 51-84.9% of the calls plot in the local PSAPs jurisdiction and CHP transferred > 90% of the calls then the sector can route to the local PSAP If 51-84.9% of the calls plot in the local PSAPs jurisdiction but CHP transferred < 90% of the calls then the sector will require further analysis before a decision will be made by CHP If 50.9% or < of the calls plot in the local PSAP jurisdiction & the remainder of the calls plot in CHPs jurisdiction then the sector will remain with CHP If <50 calls sector remains with CHP 27
RED Schedule Phase 1 - Commenced July 14, 2008 Phase 2 - Commenced January 9, 2009-70% complete by June 30, 2009
How to measure results? The goal is to have shorter wait times and improve service to the W 9-1-1 calling public. How do we quantify it? Challenges: inconsistency of data from different PSAPs non-standardization of equipment / controllers different switch settings determine CDR output & format
Post Cut-over Analysis
Post Cut-over Analysis Pre Cut-over 45% of calls were transferred Post Cut-over only 15% of calls transferred
