Table 4 Driver behavior indices
From: Study protocol for “In-vehicle sensors to detect changes in cognition of older drivers”
Categories | DBIs | Data Analytics |
|---|---|---|
Travel Patterns | number of trips, miles driven, miles on the highway, miles during the night, daytime, and severe weather, highway miles, etc. | map-matching, data queries, map data, weather data |
Abnormal Driving | wayfinding, getting lost, ignoring traffic signals and signs, near-collision events, distraction, drowsiness, etc. | machine vision, shortest path, outlier detection, trajectory clustering, frequent graph mining |
Reaction time | reaction time to traffic light change, front-vehicle taillight, pothole, etc. | vision sensing, data fusion, vibration analysis, machine learning |
Braking Patterns | eye movements and IMU data at stop signs, traffic signals, tail lights, losing focus, potholes, etc. | signal processing, gaze estimation, data mining, machine vision |
