A data extraction program was developed to gain real-time access to the data being generated by DriveSafety research simulators. A socket is defined in the initialization script for a scenario. When the scenario is run, the socket is created and the connection with the data extraction program is established. These particular simulators all use the same HyperDrive Authoring Suite for developing scenarios and therefore the program is suitable for use by all. An initialization script was written to search for the activation of triggers to gain access to data about specific points in the scenario. Similarly, a script was written to search for active data collection zones. The scripts use a virtual trigger which looks for activation at a rate of 60 Hz per second. When the search conditions are met, the values of the specified data collection variables are sent to the data extraction program via the socket. The function of the data collection program was verified by comparing the extracted data to that collected by the simulator during a simulation. For the point data, the two datasets were identical when the data collection rate was set to 60 Hz. At lower rates, the percentage of matching records dropped. This result was expected as the recording of trigger activation is not guaranteed at lower rates. For the segment data, the two datasets were again identical when the data collection rate was 60 Hz. These results confirm that the data collection program is functioning as designed. The data extraction program and the simulator collect data at the same time but the simulator data collection file is only accessible after the simulation has ended. The data extraction program makes the data available in real-time and can therefore be used to monitor and evaluate performance as the participant drives the simulator vehicle. This functionality is valuable for evaluating whether participants are learning, have learned or are not learning to drive while driving a practice scenario. The data extraction program also provides the user more flexibility in data collection options. The simulator and the data extraction tool can collect data at different rates and collect a different set of data collection elements. This functionality is valuable when the user is interested in collecting data for two different purposes. Each can be used to filter the data in a different manner.
