USDOT proposes speed limiters for large commercial vehicles; potential savings up to ~$1B in fuel each year depending on limit
August 26, 2016
The US Department of Transportation’s (DOT’s) National Highway Traffic Safety Administration (NHTSA) and Federal Motor Carrier Safety Administration (FMCSA) are proposing equipping heavy-duty vehicles with devices that limit their speeds on US roadways, and requiring those devices be set to a maximum speed, a safety measure that could save lives and more than $1 billion in fuel costs each year.
Specifically, NHTSA is proposing to establish a new Federal motor vehicle safety standard (FMVSS) requiring that each new multipurpose passenger vehicle, truck, bus and school bus with a gross vehicle weight rating (GVWR) of more than 11,793.4 kilograms (26,000 pounds) be equipped with a speed limiting device.

July 27, 2016
The US National Transportation Safety Board issued its preliminary report for the investigation of the fatal 7 May 2016, highway crash in Florida involving the Tesla Model S and Autopilot. The preliminary report does not contain any analysis of data and does not state probable cause for the crash.
The preliminary report details the collision involving a 53-foot semitrailer in combination with a 2014 Freightliner Cascadia truck tractor and the 2015 Tesla Model S. According to system performance data downloaded from the car, the indicated vehicle speed was 74 mph (119 km/h) just prior to impact; the posted speed limit was 65 mph (105 km/h).
CMU study: even partially-automated crash avoidance delivers financial and safety benefits
July 19, 2016
A new cost-benefit analysis by researchers at Carnegie Mellon College of Engineering shows that the public could derive economic and social benefits today if partially-automated collision avoidance features were deployed in all cars.
In a paper published in the journal Accident Analysis & Prevention, they evaluated the benefits and costs of fleet-wide deployment of three such technologies: blind spot monitoring; lane departure warning; and forward collision warning crash avoidance systems within the US light-duty vehicle fleet.
Consumer Reports calls on Tesla to disable and update auto steering function, remove “Autopilot” name
July 14, 2016
Consumer Reports is calling on Tesla to disable the automatic steering function in the Autopilot driving-assist system available in its Model S vehicles until the company updates the function to confirm that the driver’s hands remain on the steering wheel at all times.
The consumer organization, which has owned and tested three Teslas (2013 Model S 85, 2014 Model S P85D, and 2016 Model X 90D), said that Tesla should also change the name of the Autopilot feature because it promotes a potentially dangerous assumption that the Model S is capable of driving on its own.
CDC: US has highest motor vehicle crash death rate among high-income countries; could be cut in half with proven strategies
July 07, 2016
About 90 people die each day from motor vehicle crashes in the United States, resulting in the highest death rate among 19 high-income comparison countries, according to the latest Vital Signs report by the Centers for Disease Control and Prevention (CDC). There were more than 32,000 crash deaths in the US in 2013, with more than $380 million in direct medical costs.
Athough the US has made progress in road safety—reducing crash deaths by 31% from 2000 to 2013—other high-income countries reduced crash deaths by an average of 56% during the same period. Lower death rates in comparison countries, as well as the high prevalence of risk factors in the US, suggest that more progress can be made in saving lives, according to the CDC. Compared with other high-income countries, the US had the:
NHTSA projects 7.7% increase in US traffic fatalities for 2015 year-on-year; significant increase in motorcyclist and non-occupant deaths
July 02, 2016
A just-released National Highway Traffic Safety Administration (NHTSA) statistical projection of traffic fatalities for 2015 estimates that 35,200 people died in motor vehicle traffic crashes—an increase of about 7.7% as compared to the 32,675 fatalities reported in 2014. If the 35,200 figure turns out to be accurate, this will mark the highest level of fatalities since 2008, which saw 37,423 fatalities.
Federal Highway Administration (FHWA) preliminary data shows that vehicle miles traveled (VMT) in 2015 increased by about 107.2 billion miles—about a 3.5% increase. The fatality rate for 2015 increased to 1.12 fatalities per 100 million VMT, up from 1.08 fatalities per 100 million VMT in 2014—about a 3.7% increase. Fourth quarter of 2015 represents the fifth consecutive quarter with year-to-year increases in fatalities as well as the fatality rate.

IIHS: Speed limit increases in US caused 33,000 deaths over 20 years
April 14, 2016
A new Insurance Institute for Highway Safety (IIHS) study shows that increases in speed limits over two decades have cost 33,000 lives in the US. In 2013 alone, the increases resulted in 1,900 additional deaths, essentially canceling out the number of lives saved by frontal airbags that year.
Charles Farmer, IIHS vice president for research and statistical services and the author of the study, looked at deaths per billion miles traveled by state and roadway type. Taking into account other factors that affected the fatality rate—including changes in unemployment, the number of potential young drivers (ages 16-24) and per capita alcohol consumption—he found that each 5 mph increase in the maximum speed limit resulted in a 4% increase in fatalities. The increase on interstates and freeways, the roads most affected by state maximums, was 8%.
RAND: Autonomous vehicles cannot be test-driven enough miles to demonstrate their safety; alternative testing methods needed
April 13, 2016
Autonomous vehicles would have to be driven hundreds of millions of miles and, under some scenarios, hundreds of billions of miles to create enough data to clearly demonstrate their safety, according to a new report from RAND, a non-profit research organization.
Under even the most-aggressive test driving assumptions, it would take existing fleets of autonomous vehicles tens and even hundreds of years to log sufficient miles to adequately assess the safety of the vehicles when compared to human-driven vehicles, according to the analysis.

NHTSA proposes updating electrical safety requirements for fuel cell and mild hybrid vehicles; alignment with int’l standards
March 04, 2016
The US Department of Transportation's National Highway Traffic Safety Administration (NHTSA) issued a notice of proposed rulemaking (NPRM) to update electrical safety requirements for hydrogen fuel cell vehicles and mild hybrid vehicles.
The NPRM proposes adding an optional method for post-crash electrical safety into the standard, FMVSS No. 305, that involves physical barriers to prevent electric shock due to direct or indirect contact of high voltage sources. This proposed optional method affords the same level of electric shock protection as the other methods for electrical safety currently in FMVSS No. 305 and would enable innovative powertrain technologies. The proposed updates to FMVSS No. 305 align the standard with international regulations and the latest version of the voluntary industry standard, SAE J1766, “Recommended Practice for Electric and Hybrid Electric Vehicle Battery Systems Crash Integrity Testing”.

Bosch says its haptic gas pedal can reduce fuel consumption up to 7%; safety warnings via nav and V2X systems
January 25, 2016
The automotive industry has been exploring the use of haptic gas pedal technologies as a way to reduce fuel consumption and increase safety by signaling the driver using a mechanism such as a vibration or a counterforce in the accelerator pedal. Continental announced its Accelerator Force Feedback Pedal in 2010, Frost & Sullivan anticipates wide premium-segment deployment of the active gas pedal technology post-2018 (earlier post); and Mercedes-Benz offers the technology in the C 350 PLUG-IN HYBRID (earlier post).
Bosch now says that its active gas pedal allows drivers to reduce fuel consumption by as much as 7%. This is possible because the gas pedal can be networked with other automotive functions, such as the transmission. Up to now, the only indication drivers have had of the best time to shift gear has been in the form of small arrows on the instrument display. The active gas pedal comes with the option of a palpable indication of the best time to shift gear.

IAV and Microsoft demonstrate connected highly automated driving vehicle for enhanced safety; cloud-based analytics and big data
January 11, 2016
At CES 2016 last week, IAV and Microsoft demonstrated a connected highly automated driving (CHAD) vehicle capable of connecting with the Microsoft Azure cloud and Windows 10 to enable communication that helps prevent vehicle and pedestrian accidents and increases driving comfort and convenience. This vehicle-2-x communication (V2X) connectivity approach uses data from the vehicle’s surroundings to improve smart service for convenience and enhance safety by anticipating and mitigating potential hazards.
The two demonstrated a use case pf the approach: a pedestrian with a wearable device is walking toward the road, concealed by a parked vehicle. The device is located by nearby intelligent roadside infrastructure that is connected to the Azure cloud. The CHAD vehicle then receives a V2X warning that permits the safe, convenient adjustment of its driving dynamics in order to detect and avoid the hazard.

UCLA researchers develop exceptionally strong and lightweight new metal nanocomposite
December 24, 2015
A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal nanocomposite with extremely high specific strength and modulus, or stiffness-to-weight ratio. The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.
To create the super-strong but lightweight metal, the team developed a new way to disperse and stabilize nanoparticles in molten metals. They also developed a scalable manufacturing method that could pave the way for more high-performance lightweight metals. A paper on their work is published today in Nature.
Continental to demonstrate dynamic eHorizon technology during CES; Connected Energy Management and Blind Curve Warning
December 16, 2015
Continental will demonstrate its latest generation of eHorizon technology during CES next month in Las Vegas. Continental will show with two use cases based on dynamic eHorizon technology—Connected Energy Management and Blind Curve Warning—how data from the cloud can predict the road ahead, ultimately reducing fuel consumption and making vehicles safer. Both demonstrations will be conducted on public roads in Las Vegas.
Continental has already shown that the static eHorizon—introduced commercially in 2012—which uses certain data from a static map stored in the vehicle, enables a significant reduction of fuel consumption (around 3% on average). As a result of this success, Continental has taken the development of eHorizon even further by using the cloud and crowd intelligence to enhance the digital map in the dynamic eHorizon Backend with fresh and accurate information.
