Applying Automotive EDR Data to Motorcycle Accident Reconstruction

Applying Automotive EDR Data to Motorcycle Accident Reconstruction

I just made a proposal to SAE for a new course titled “Applying Automotive EDR Data to Motorcycle Accident Reconstruction.” Here are some of the specifics, which I would love your thoughts on. What would improve this concept? What would make this course more useful. I’ll be offering this course for the first time on November 6, 2019 in Denver, along with Alan Moore’s class “Accident Reconstruction, the Automomous Vehicle and ADAS” (November 5) and Neal Carter’s new class on using drones for mapping accident sites (November 7). Hold these dates if you are interested…more info to come.

Braking and Swerving Capabilities of Three-Wheeled Motorcycles

With the three-wheeled motorcycles in this study, the average decelerations for the tests that utilized both the front and rear brakes varied between 0.74 and 0.91 g. This range is situated in the upper half of the corresponding range for two-wheeled motorcycles (0.54 to 0.96 g). This is consistent with the fact that two-wheeled motorcycles require more skill for braking since there is more of a risk of capsizing if the rider locks up a wheel, particularly the front. For the three-wheeled motorcycles, less skill is required since the risk of capsizing is minimal, and the rider can lock up the wheels.

Motorcycle Accident Reconstruction: Lane-Splitting, Lane-Sharing, and Filtering in California

Motorcycle Accident Reconstruction: Lane-Splitting, Lane-Sharing, and Filtering in California

Lane-sharing is the practice by a motorcyclist of sharing a lane with another vehicle. Lane-splitting is the practice by a motorcyclist of riding between streams of traffic by riding on or near the striping between lanes. Filtering, which seems to be a term frequently used outside of the United States, is the practice by a motorcyclist of riding between lines of stopped or nearly stopped traffic at a traffic signal. The terms lane-splitting and lane-sharing are often used interchangeably and often the term lane-sharing is used as a catch-all term for all of these practices. These practices, which are allowed in California, allow a motorcyclist to drive faster than the surrounding traffic in congested or stop-and-go traffic [1, 2]. They also give motorcyclists more options for how they position themselves on the roadway, allowing them to “strategically place themselves in pockets of lower congestion during commute traffic” and to “distance themselves from safety hazards from larger vehicles beside or behind them, or from hazards presented by highly congested clusters of traffic” [2].

Motorcycle Accident Reconstruction: Applicable Error Rates for Struck Vehicle EDR-Reported Delta-V

Motorcycle Accident Reconstruction: Applicable Error Rates for Struck Vehicle EDR-Reported Delta-V

I’m in the midst of preparing 2 articles and a presentation for the upcoming EDR Summit in Houston (March 4-6, 2019). My topic is the use of struck vehicle EDR-data when reconstruction motorcycle-versus-passenger vehcile collisions. I thought I would put a teaser on the topic out into the world and also, hopefully, pass along some useful information. I’d love your thoughts on this topic. Read this post and then reach out to me at nrose@kineticorp.com or leave comments on the post. Thanks and I’ll see you in Houston!

Forensic Acquisition of Vehicle Infotainment Systems Data

Forensic Acquisition of Vehicle Infotainment Systems Data

Hey, everybody. In this article I’m passing along a conversation I recently had with Will Bortles of Kineticorp about the research he just published at the 2017 Society of Automotive Engineers World Congress. This research relates to methods for acquiring data from passenger vehicle infotainment systems.

PC-Crash is a vehicular accident simulation software that is widely used in the accident reconstruction community. Later parts of this article will review the prior literature that has addressed the capabilities of PC-Crash along with its accuracy and reliability for various applications (planar collisions, rollovers, and human motion). I actively use PC-Crash software in my accident reconstruction practice.
