Abstract:

The Drunk Driving Warning System (DDWS) is a vehicle-mounted device for testing driver impairment and activating alarms. The driver must pass a steering competency test in order to drive the car in a normal manner. The emergency flasher system operates when the test is failed; and if the car is driven faster than 10 mph, the horn honks periodically, once per second. The DDWS concept and hardware were developed under earlier contracts. The purpose of this work was to evaluate the feasibility of the concept, both in its sensitivity to alcohol impairment and in terms of various practical considerations in assigning the device to DWIs as a judicial sanction in a probationary setting. Volume I of the final report focuses on optimizing and validating the sensitivity of DDWS to alcohol impairment. Background on DDWS development and mechanization is given, followed by reanalysis of past performance data and optimization of test parameters. The final system configuration was tested in a laboratory experiment. The discriminability of the test strategy to BAC (blood alcohol concentration) is confirmed. The ability of DDWS to discriminate impaired performance in a driving simulation is also demonstrated. Based on the analysis, optimization, and experimental validation of DDWS performance, recommendations are given for test application and training procedures. These recommendations apply to the field test evaluation described in Volume II of this report. /Abstract from report summary page/
