Ascertainment of On-Road Safety Errors Based on Video Review

Lateral Control in a Driving Simulator: Correlations with Neuropsychological Tests and On-Road Safety Errors

“…After the drive was completed, the videos were reviewed by a professional driving instructor; not present during the drive (Dawson et al, 2009; Uc et al, 2009; Dawson et al, 2010b). The frequency, type and location of driving safety errors were recorded, with errors observed in 13 different categories: starting and pulling away from the curb, traffic signals, stop signs, turns, lane observance, lane changes & merging, speed control, parallel parking, railroad crossings, curves, overtaking, backing up, and miscellaneous.…”

Effects of Familiarity and Age on Driver Safety Errors During Wayfinding

“…This approximate 45-minute drive was conducted in Iowa City and the surrounding areas. Videos taken by on-board cameras (Rizzo, McGehee, Peterson, & Dingus, 1997) were reviewed by a professional driving instructor, who counted the number type, and location of safety errors made by each driver, as detailed in (Dawson, Rizzo, Anderson, Dastrup, & Uc, 2009b). For this report, we focused on the total number of safety errors made during the navigation task.…”

Road safety in drivers with Parkinson disease

“…18,19 As shown in our previous work, 11 the driving instructor reviewed tapes with a multiplex view using 4 channels of video (including forward roadway the driver should see and position of the car relative to the lane) with superimposed digital driving data, which included speed, enabling comparison of the actual speed to the speed limit at any moment of the drive and detection of lane deviation errors. This approach allowed a standard review of all drives, including multiple views of the driver, car, road, and traffic.…”

“…The reviewer assessed the number and type of safety errors committed by the subjects, using a list of 76 error types (e.g., "unsafe passing") organized into 15 categories (e.g., "stop signs," "lane observance"). 18,19 This list was based on the Iowa Department of Transportation's Drive Test Scoring Standards ( September 7, 2005, version). The subjects were told to drive as they would in their usual life and there was no overall pass/fail judgment.…”

“…Of the 76 error types, 30 were classified as "serious," which were seen across different error categories. 18,19 The "serious" errors were those that were classified as "failure" errors by the Iowa Department of Transportation. However, as the subjects did not take this road test as an official licensing test and we did not use a pass/fail system, we classified these errors as "serious" errors.…”
