22 Significant correlajons were detected between SS ED and ED HDD The analysis of the SS ED data indicates a possible temporal trend in the incidence of MVC- related injuries in NE There is a possible associajon between weather and entertainment events and spikes in MVC- related injury

24 MVC- related injury in SS ED data is highly correlated with ED HDD SS ED data can be used for the Jmely idenjficajon of MVC- related injuries in Nebraska

25 QuanJfy the burden of weather related MVC by locajon of the incident and other relevant variables Improve methods to combine SS, EMS and public safety informajon to idenjfy MVC hot spots
