Epidemiology Course Projects

Project Description The objectives of this study were to evaluate risk factors associated with traffic safety. The risk factors included driver characteristics, driver behavior, vehicle, and driving environmental conditions. The study used epidemiological methods to evaluate driving risk factors using SHRP2 NDS data. Data Request Scope The data included crash, near-crash, time series data and balanced baseline reduction data. The study also used driver demographic information. Data Specification The SHRP2 variables included: 1.) Event table - Please see attached data dictionary. 2.) Driver-level information for all SHRP2 participants - Please see attached data dictionary. 3.) Vehicle-level information. * Vehicle ID * Driver-ID * Cruise Control status 4.) Trip-level information (for all trips where cruise control was available): * Trip ID * Driver ID * Start timestamp * End timestamp * Cruise Control Active (Y/N) 5.) Trip summary information: * Driver ID * Trip ID * Trip Duration * Mean Speed * Standard Deviation of Speed * Min. Speed * Max Speed * Trip Start Local Time of Day * Trip End Local Time of Day 6.) Speed and Roadway Information (for all trips where cruise control was available): * Trip ID * Start Timestamp * End Timestamp * Speed * Speed Limit * Roadway Functional Class
