Boyette Road Pedestrian Case Study
RECONSTRUCTION
PRE-CRASH:
On 12-29-2016 at approximately 0315 hours, a 2015 Nissan Altima was westbound on Boyette Road in the outside lane, approximately .37 miles east of and approaching the intersection of McMullen Road. The driver of Nissan did not see Pedestrian 1 enter the roadway from the north road edge. Pedestrian 1 was walking from a private driveway at 12012 Boyette Road, southbound across Boyette Road from the north side of Boyette Road, where there is not a marked crosswalk, or any type of pedestrian signals. There was a streetlight approximately 40 feet north of the north road edge of Boyette Road along the west side of the driveway near the entrance to 12012 Boyette Road. The streetlight did not illuminate Boyette Road. There was a concrete sidewalk approximately 4.5 feet north of the north road edge which ran parallel with Boyette Road. The sidewalk extends from the west side of the driveway to a marked crosswalk approximately .36 miles away. The sidewalk also continues from the east side of the driveway to a marked crosswalk …show more content…
This calculated speed of the pedestrian is a conservative estimate of the speed of the Nissan. Normally, a pedestrian does not obtain 100% of the vehicle’s striking speed. A pedestrian struck by a low profile vehicle, (leading edge is at or below 25” / IPTM: Vehicle-Pedestrian-Bicycle Collision Investigation Manual / Tony L. Becker)} will gain a lower percentage of the vehicle’s impact speed. (Pedestrian Accident Reconstruction and Litigation 2nd Edition / Jerry J. Eubanks & Paul F. Hill Esq.) The Searle equation recommends a friction coefficient of .66 on asphalt and knowing the throw distance and the center of gravity for the pedestrian. {Center mass of the pedestrian was calculated to be 3.87 feet or
