Data Source
The Bureau of Transportation Statistics (part of the U.S. Dept. of Transportation) gathers data on the estimated 6.4 million vehicle accidents reported each year. Data are accessible at http://www.transtat.bts.gov. The most recent sample of 55,000 records relates to 2001 vehicle accidents. From this data, we selected a random sample of 10,000 records for this project.
Objective
Objective
– Evaluate the role of physical environment in
vehicle accidents that result in injuries, specifically
Profile variables of physical environment that increase the probability of injuries in vehicular accidents Predict the probability of injuries in accidents based on the selected variables of physical environment
Hypothesis
– Variables of physical environment have major influence on the
probability of injury in vehicular accidents
Clients for this Study
Federal Agencies and Dept. of Transportation State and County Governments Automobile Industry Insurance Industry – Health, Auto Businesses in road safety Commuters
