The second session today is "Commercial Vehicle Original Equipment Manufacturer (OEM) (and Supplier) Perspectives," with speakers from Daimler Trucks, Volvo Trucks, Navistar, and Meritor Wabco.
The first speaker is Paul Menig from Daimler Trucks North America. Mr. Menig is discussing Safety from Start to Finish. He points out that a heavy vehicle has approximately 10 computers (engine, transmission, ABS, and so on). He points out that the general trend in the trucking industry has been for new technology to begin as an aftermarket option and then move toward greater integration (prep package, pre-delivery) until it becomes an OE factory option.
The next speaker is Timothy LaFon from Volvo Trucks North America. Mack and Volvo are headquartered in Greensboro, NC. The major control units on these vehicles are ABS, Airbags, Electronic Stability Control (ESC), EECU and VECU (Engine and Vehicle Electronic Control Units, respectively). There is also a light control module. He points out that ECUs were not developed for accident or crash investigations, and that physical data need to be considered as well as electronic data.
Beginning in 2002, Volvo does have "freeze frame" data associated with fault codes. Mr. LaFon announced that Volvo DOES HAVE INCIDENT LOGGING. The Volvo EDR, which begins in 2010, has two events: one associated with a Last Stop and one associated with a wheel speed trigger of 10mph/sec. There is one fault associated with VECU faults and one with EECU faults. These have 60 seconds of pre-event and 30 seconds of post-event data at 4Hz.
Airbag control units can be downloaded but need to be sent back to Europe. ABS and ESC systems should be downloaded by the supplier (e.g., Bendix or Wabco).
THIS IS THE FIRST OFFICIAL, PUBLIC ANNOUNCEMENT FROM VOLVO THAT THEIR TRUCKS HAVE AN EDR.
As of now, Mr. LaFon states that all Volvo VECU/EECU downloads must be handled by Tim Cheek (Delta-V Forensic Engineers) or John Steiner (KEVA Engineering). Mr. LaFon states that the reason for this is that they (Volvo) have concerns about data accuracy, evidence spoliation, and that Volvo has no method for selling the EDR Retrieval Tools to the public.
I think it's worth pointing out here that the engineering, research, and crash investigation community have successfully dealt with these very same issues with the other engine manufacturers' EDRs, including self-funding dozens and dozens of research papers over (literally) decades in light vehicle and heavy vehicle EDRs. Ironically, most of that research has been published though SAE.
The third speaker is Alan Korn from Meritor Wabco. Mr. Korn is describing the data monitoring system that Meritor Wabco offers called Safety Direct. This system can monitor and record driver behavior and alert a safety manager of aggressive driving. Safety Direct monitors and records events (10 seconds before and after), and can include video. It can be downloaded directly from the vehicle or it can be uploaded by a telematics system.
The final presentation in this group is from Eric Swenson of Navistar. Mr. Swenson is discussing the electrical, mechanical, space, and power requirements for a J2728-compliant HVEDR.

The second day of the SAE 2011 Highway Vehicle Event Data Recorder (EDR) Symposium kicks off with a morning session on international perspectives on EDRs. Speakers from Germany, Switzerland, Sweden, and Japan will be up this morning.
The session begins with Ralph-Roland Schmidt-Cotta from Continental GmbH in Germany. Herr Schmidt-Cotta is covering the historical background of EDRs. This history goes back to 1971, when mechanical tachographs were mandated in the European Economic Community. In 1973, the German Traffic Court Conference called for an Accident Data Recorder. Currently, the EU is attending to vulnerable road users (cyclists and motorcycle users) because fatalities among these road users are increasing relative to the number of overall fatalities. EDR technology may assist in these incidents. The European Parliament will be considering several bills that may require EDR technology in Europe for accident research, but the use of EDR data in civil and criminal proceedings will likely be left to the national level.
The second speaker, from the Japan Automotive Research Institute (JARI), is Nobuyki Uchida. His presentation is Human Error Analysis in Pedestrian Incidents. In Japan, pedestrian accidents account for approximately 35% of fatalities. In response to this, JARI conducted a naturalistic driving study using video recorders. Five video cameras were linked to vehicle onboard data, such as speed pulse and brake activations. Based on their research, attentional allocation and temporal obstructions were causal factors in drivers making the incorrect decision that it was safe to turn. JARI will be working to develop pedestrian sensors that can assist drivers in avoiding these crashes.
The third speaker is Tobias Aberle, from AXA Winterthur in Switzerland. AXA implemented a crash data recorder for its customers and offered a 15% discount on insurance premiums. These crash recorders are specifically designed for capturing data after an incident, and they provide overwrite protection, backup power, and record at higher resolution during the crash than during the seconds leading up to and after it. This is quite nice, since it was designed for accident investigations. I am a bit surprised that the crash recorder is a robust accelerometer and doesn't include driver inputs such as throttle position or brake pedal position.
The final speaker of the first session today is Dr. Anders Ydenius from Folksam Research in Sweden. Dr. Ydenius has analyzed crashes with EDR-equipped vehicles between 1992 and 2008, with a specific focus on road design and its interaction with driver and occupant injuries. Crashes were analyzed by speed limit, crash type, friction conditions, and fixed object (for single vehicle crashes). One of the (several) interesting conclusions was that wire guardrails and W guardrails offer significant potential for injury mitigation over concrete barriers.
This is one of the coolest aspects of this seminar: having renowned international speakers from Europe and Asia offers excellent perspective.

The last session of a great day in Danville, Virginia, is on standards development, beginning with SAE J1698, SAE J2728, and International Standards Organization (ISO) Activity.
The first speaker is Brian Everest, speaking on the objectives of the light vehicle Event Data Recorder (EDR) Standards Committee. The updated Standard will address the data, the tool, and the extraction. There are five task forces, focusing on: 1) updating the text and definitions to be current with new and future technology; 2) defining new future parameters and technologies (like brake pedal position!); 3) tamper resistance, physical integrity, and standard data retrieval communications; 4) recommended practices for any tool used for accessing the EDR; 5) ensuring data integrity.
That's a lot of beneficial work!
The next speaker is Carl Munch, speaking on test protocols for compliance with Part 563. This is the part of the committee's work that will ensure that data from EDRs are recorded and reported accurately, including synchronizing the parameters. The committee has looked at reporting of longitudinal delta v, max delta v, and time to max delta v.
The third speaker is Lee Lackey, from Noregon Systems, discussing the J2728 committee. This committee has developed the Standard for HVEDRs. There were four main groups in Tier 1, which is the first stage of the Standard: data definitions, data extraction, data file format, and event triggers. There were also groups for performance specs and survivability, which come into play more in Tier 2 than in Tier 1.
The J2728 Standard has 16 Header parameters, 1 Footer parameter, and 20 data elements. The data will be output into a CSV file that can be validated, and requires EDRs to have sufficient reserve power to write data in the event of a complete power failure. At this point, the Standard is in the final stages of meeting some requests from the NTSB.
The last speaker of the day is Joseph Marsh, from Ivy Consultancy, describing the International Standards Organization's activity with EDRs. These are under TC22 / SC 12 / WG7, the Traffic Accident Analysis Methodology group. This is mostly concerning the collection of aggregate EDR data.
This was an excellent day--very much worth the time and money. I'm looking forward to tomorrow!

Session Three of the SAE 2011 Highway Vehicle EDR Symposium has five speakers who are trucking safety professionals discussing their and their companies' experience with Electronic On-Board Recorders (EOBRs) and various Event Data Recorder (EDR) systems.
The first speaker after lunch was Jerry Waddell from Cargo Transporters. Mr. Waddell discussed their positive experience with Critical Event Reporting, especially in notifying management of hard brake events.
The second speaker is Brett Graves from Maverick Transportation. Maverick Transportation is using predictive modeling to enhance the safety of their fleet. Their predictive models have greatly reduced their reportable and preventable rates per million miles.
The third speaker is Michael Baker from Usher Transport. Usher Transport has had only five rollovers in the 27 years that Mr. Baker has been there in safety. WOW!!! Some statistics from his presentation: 1/5 rollovers have two contributing factors: inattention and drowsiness. 1/5 rollovers results from excessive cornering speed. Lowering a trailer three inches increases stability by 10%. More stats: freeway off-ramps account for 7% of rollovers; interstate highways account for about 31%. State highways account for the remaining 68%. Forty-seven percent of rollovers result from lane departures. Only 9% result from cornering too fast.
The fourth speaker is James Burg of James Burg Trucking Company (JBTC). JBTC uses Drivecam Video Event Recorders and hauls normal and oversized loads. JBTC uses Drivecam as a training tool and also in incident and crash investigations. It has helped with company policy compliance, driving safety, and driver training. JBTC really works to make their drivers better drivers.
The fifth speaker is Sam Faucette from Old Dominion Freight Line. Old Dominion is the largest LTL carrier using EOBRs. They use a list of several variables that are monitored in order to evaluate safe, efficient operations. Like the other companies, they are turning "data" into useful information.
All five companies represented have one thing in common. They view safety as a human issue and rely on the EDR systems as tools to help the safety manager make good decisions and improve driver performance. Although they each use different techniques and different tools, they are all focused on developing high quality, well-trained, professional drivers.

The second session is Passenger Car Original Equipment Manufacturer (OEM) Event Data Recorders (EDRs). The first speaker is James Engle from Ford. His presentation is an overview of the Ford EDR systems (powertrain control module, restraint control module). He is discussing how Ford EDRs are changing to become Part 563 compliant. The most notable change from a crash investigation standpoint is that data won't be recorded on the PCM anymore.
Next speakers are from Chrysler: Lisa Fodale & James Bielenda. Ms. Fodale is describing the three phases of Chrysler EDRs (Phase 1: 2005-2007MY, Phase 2: 2008-2009MY, Phase 3: 2010-2012). She's provided a really good, succinct summary of the increasing amount of data supported in these EDRs. Mr. Beilenda provided a great segment on numerous applications of Chrysler EDRs. Both sections were great summaries of where these two manufacturers are with EDRs and Part 563 compliance.

The Institute for Advanced Learning and Research is an awesome facility. One really nice aspect of the room is that seating is at tables with five (comfortable) chairs. There's plenty of space, room for briefcases and backpacks, and the wifi is great! Opening comments from the Hon. Ann Ferro were delivered by video--tough to pull off, but with the technology in this building and the organizers' preparation, it came off quite well.
First speaker is Dr. Gabler from Virginia Tech. Dr. Gabler is discussing the "Big Picture" on light vehicle Event Data Recorders (EDRs). In general, the topic is how he and NHTSA are using EDR data to improve vehicle safety. It's pretty amazing, sitting here today, to think that 10 years ago Dr. Gabler was asked IF EDR data could be used for safety research. Personally, the most fascinating thing in Dr. Gabler's presentation is the use of EDR data for improving triage decisions after serious crashes.
Next speaker is Sandeep Kar. This presentation is about trends in telematics and urbanization. The topic of population growth patterns (mega cities to mega regions and mega corridors) affecting the development of new vehicle types is not a topic I've specifically thought about, but wow! There is incredible potential here for using telematics in a number of ways (including safety and compliance, but also emissions & logistics).
Third speaker is Joseph Kanianthra. Dr. Kanianthra is discussing the future of EDRs in safety. Ninety percent of primary causal factors are related to the operator: recognition errors, decision errors, erratic actions, fatigue, impairment, etc. Only 10% are primarily vehicle or roadway defect-related. The major idea of this presentation is that future injury and fatality prevention will be driven by prevention, more so than enhanced protection.
I think the moderator, John Hinch of NHTSA summed it up well: the big picture is bigger than any one person imagines.

US DOT Conducts Over 3000 Surprise Passenger Carrier Safety Inspections
Benjamin SmithPrincipal Technical Analyst
Messerschmidt Safety Consultants of Mississippi
The US Department of Transportation (US DOT) announced on May 27 that the Federal Motor Carrier Safety Administration (FMCSA) and its local and state law enforcement agencies conducted over 3000 surprise passenger bus inspections during a two-week period in May. These inspections resulted in 442 out-of-service citations for 127 drivers and 315 passenger transport vehicles. Additionally, the FMCSA and state safety inspectors launched 38 full safety compliance reviews of commercial passenger bus companies.
US Transportation Secretary Ray LaHood said, “During this heavy summer travel season, we will remain alert and remove from our roads any passenger bus or driver that places motorists at risk.” According to the US DOT, over the last five years, the number of unannounced commercial passenger bus roadside safety inspections and carrier compliance reviews has doubled. To learn more about this, read the US DOT news release.
In an effort to reduce all commercial motor vehicle crashes, the FMCSA has developed a new safety program called Compliance Safety Accountability (CSA). CSA includes a Safety Measurement System (SMS), which uses crash data and inspection results to identify unsafe motor carrier companies, including passenger carriers. The SMS system evaluates seven different safety performance categories, or BASICs (Behavior Analysis Safety Improvement Categories). These are: Unsafe Driving, Fatigued Driving (Hours-of-Service), Driver Fitness, Controlled Substances/Alcohol, Vehicle Maintenance, Cargo-Related, and Crash Indicator.
The US DOT estimates that passenger carriers or buses transport 750 million people each year in the US. The most recent statistics from the National Highway Traffic Safety Administration (NHTSA) show that there were 221 bus-involved fatality crashes in 2009. The number of bus-involved fatality crashes has dropped steadily since 2006, when there were 305 fatality crashes.
