- Geospatial analysis of high-crash intersections and rural roads using naturalistic driving data : final reportCannon, Brad R.; Sudweeks, Jeremy D. (National Surface Transportation Safety Center for Excellence, 2011-09-26)Despite the fact that overall road safety continues to improve, intersections and rural roads persist as trouble areas or hotspots. Using a previously developed method, naturalistic driving data were identified through intersection and rural road hotspots and compared to naturalistic driving data through similar intersections and rural road locations, but with low crash counts. Few significant differences were found between driver behaviors in the low-crash and high-crash areas of study. For the few significant differences, there was not an apparent consistent pattern. -- Report website.
- Method for identifying rural, urban, and interstate driving in naturalistic driving data : final reportCannon, Brad R.; McLaughlin, Shane B.; Hankey, Jonathan M. (National Surface Transportation Safety Center for Excellence, 2009-03-12)By employing the functionality of GIS, code was written which allows for an automated process to compare the GPS data recorded in the naturalistic driving data with geographic map data from the U.S. Census Bureau and road data from various sources, such as state departments of transportation or other providers. Points recorded in the naturalistic driving data which fall outside the boundaries of the Census Bureau's urbanized Areas or urban Clusters are determined to be rural. The points are further evaluated to determine whether or not the vehicle was being driven on an interstate highway. Points that are determined to be rural and not on interstate highways are segments of interest in addressing the rural road crash problem.
- Pilot Study of Instrumentation to Collect Behavioral Data to Identify On-Road Rider BehaviorsMcLaughlin, Shane B.; Doerzaph, Zachary R.; Cannon, Brad R. (United States. National Highway Traffic Safety Administration, 2011-04)Motorcycle-related research questions of interest to the National Highway Traffic Safety Administration (NHTSA) were reviewed. Instrumentation techniques and study procedures that have been used for light- and heavy-vehicle studies were adapted for use in answering the motorcycle-related questions. Three motorcyclists rode with instrumentation for a total of over 3,100 miles. The final data acquisition system and instrumentation recorded acceleration in three axes, yaw, pitch, roll, geographic location, rear-wheel speed, position in lane, turn-signal use, braking, range and closing speed to forward objects, and five video views. The sensor and video data were collected continuously while the bike was running. Development of helmet-mounted eye tracking and three dimensional head tracking instrumentation for use in naturalistic studies was attempted. Study components including recruiting, screening, questionnaires, and garage procedures were also tested. Analyses were conducted to illustrate possible uses of the data and to confirm the effectiveness of the adapted instrumentation. An independent evaluator reviewed the project, including the technical approach, instrumentation, data and questionnaires. Demonstration of motorcycle instrumentation that will support the majority of NHTS's motorcycle research questions was successful. Instrumentation for fine measurement of gaze location in naturalistic situations was not successful. Identification of coarse scan behavior and general areas where riders are looking (e.g., forward, left, right, down, rearward) was possible.
