This study extends the previous work of Burkey and Obeng (2004) that examined the impact of red light
cameras on the type and severity of crashes at signalized intersections in Greensboro, NC. The extension takes
the following form. First, we extend the data to cover 57 months, and to include demographics, technology
variables, the condition of a driver at the time of the crash, vehicle characteristics, land use and visual
obstruction. Second, instead of examining the impact of red light cameras, we focus on identifying the
determinants of crash severity, two-vehicle crashes, and property damage costs. The major findings are that the
safety impacts of seatbelt use outweigh the impacts of airbags deploying because the latter tends to increase
evident injuries and property damage costs, while the former reduces these injuries. We also find that head-on
collisions and under rides increase evident injuries. For two-vehicle crashes, we find that the risk of severe
injuries increases in pickup-pickup crashes and SUV-pickup crashes, while the risk of possible injuries
increases in car-truck crashes. For property damage costs, we found the condition of the driver at the time of
the crash (i.e., illness, impaired, medical condition, driver falling asleep, driver apparently normal) to be
important determinants in increasing these costs. The types of accidents that we found to increase property
damage costs are running into a fixed object and under rides. Finally, we found that property damage costs of
crashes are low where the land uses are commercial and institutional suggesting that the accidents that occur in
these areas are minor
