Natural disasters and people using mobile phones to report traffic accidents are two reasons the nation's 911 centers are occasionally overwhelmed.

According to the 9-1-1 Industry Alliance, calls are up 37% since 1999 to 260 million annually. Five million accidents occur every year, and an average of 392 natural disasters has occurred each year from 2000 to 2008.

If you have any ideas for alleviating the overload, the organization would like to know. Contact Vice Chairman Reid French at or 404-217-8542 to submit a speaker proposal for a national workshop to be held Oct. 4 — 5, 2011, at the Georgetown University Hotel and Conference Center in Washington, D.C.
