Volvo Cars providing 1,000 test vehicles for Scandinavian cloud-based project for sharing road surface information
February 13, 2015
Volvo Cars, the Swedish Transport Administration and the Norwegian Public Roads Administration are collaborating on a development and demonstration project to enable cars to share information through a cloud-based network about conditions that relate to road friction (such as icy patches). (Earlier post.) The Road Surface Information (RSI) system combines the latest generation of climate models, advanced analysis of vehicle data and a detailed statistical analysis of road sections.
With the technology development in place, the testing and validation phase is now about to begin. In this phase, Volvo Cars will both expand the test fleet 20-fold (from about 50 cars to 1,000) and broaden the test area to include two big Scandinavian cities: Gothenburg and Oslo. Together, these measures will provide a more complete picture of how the system will work in real winter traffic conditions.
NHTSA releases two new studies on impaired driving on US roads; drunk driving down, drug use up
February 07, 2015
The nation’s decades-long campaign to combat drunk driving continues to make roads safer, but use of marijuana and prescription drugs is increasingly prominent on the highways, creating new safety questions, according to a pair of new studies released by the Department of Transportation’s National Highway Traffic Safety Administration.
One study, the latest version of NHTSA’s Roadside Survey of Alcohol and Drug Use by Drivers, found that the number of drivers with alcohol in their system has declined by nearly one-third since 2007, and by more than three-quarters since the first Roadside Survey in 1973. But that same survey found a large increase in the number of drivers using marijuana or other illegal drugs. In the 2014 survey, nearly one in four drivers tested positive for at least one drug that could affect safety.
Battelle/Concurrent Technologies Corporation technology positioning paper: Improving Li-ion battery safety without decreasing energy density
February 05, 2015
Ed. introduction: The following technology positioning paper is a joint effort by a team from Battelle and Concurrent Technologies Corporation (CTC). The paper outlines the technology landscape and the opportunities that exist in the area of improved Li-ion battery safety.
Energy is a common technology area on which both research organizations focus in different ways, noted Dr. Vicki Barbur, CTC Senior Vice President and CTO. The two have decided that Li-ion battery safety is an area of opportunity for each. Supported by an ARPA-E award, Battelle recently developed an optical sensor to monitor the internal environment of a lithium-ion battery in real-time. (Earlier post.) The organizations intend to pursue further efforts directed toward safety in relation to Li-ion battery technology. Interest and involvement from external clients would be welcomed.
NHTSA announces follow-up recall of 2.12 million cars and SUVs over TRW airbag defects
January 31, 2015
US Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles from model years 2002 to 2004 for a defect that may cause airbags to deploy inadvertently.
The vehicles were subject to earlier recalls to address a problem with an electronic component manufactured by TRW that caused some airbags to deploy in the absence of a crash. The recalls will provide vehicle owners with a new remedy after the manufacturers’ original attempts to fix the defects proved ineffective in some vehicles.
NHTSA to include 2 automatic emergency braking systems in NCAP recommendations
January 25, 2015
The National Highway Traffic Safety Administration (NHTSA) plans to add two advanced automatic emergency braking (AEB) systems—crash imminent braking (CIB) and dynamic brake support (DBS)—to the recommended advanced safety features included under its New Car Assessment Program (NCAP).
The addition is the latest in a long history of safety innovations covered in a new NHTSA's new report, which uses data from the agency’s Fatal Accident Reporting System to create a statistical model that estimated safety technologies have saved 613,501 lives since 1960.
Jaguar Land Rover “Bike Sense” uses color, sound and vibration to help prevent accidents involving bicycles and motorbikes
January 21, 2015
|Jaguar Land Rover is developing a range of new technologies that would use colors, sounds and touch inside the car to alert drivers to potential hazards and prevent accidents involving bicycles and motorbikes. Click to enlarge.|
At its Advanced Research Center in the UK, Jaguar Land Rover is developing a range of new technologies it calls “Bike Sense” that uses colors, sounds and touch (vibration) inside the car to alert drivers to potential hazards and prevent accidents involving bicycles and motorbikes. Nearly 19,000 cyclists are killed or injured on UK roads every year.
Sensors on the car will detect when another road user is approaching and identify it as bicycle or motorbike. Bike Sense will then make the driver aware of the potential hazard before the driver sees it. Rather than using a generic warning icon or sound, which takes time for the driver’s brain to process, Bike Sense uses lights and sounds that the driver will instinctively associate with the potential danger.
UMTRI researchers suggests safety expectations for self-driving vehicles may be overblown
January 16, 2015
In a new white paper, a team from the University of Michigan Transportation Research Institute (UMTRI) discussed issues related to road safety with self-driving vehicles and concludes that expectations for improved road safety may be, in some cases, overblown.
In their paper, Michael Sivak and Brandon Schoettle assessed safety from four perspectives: 1) Can self-driving vehicles compensate for contributions to crash causation by other traffic participants, as well as vehicular, roadway, and environmental factors? (2) Can all relevant inputs for computational decisions be supplied to a self-driving vehicle? (3) Can computational speed, constant vigilance, and lack of distractibility of self-driving vehicles make predictive knowledge of an experienced driver irrelevant? (4) How would road safety be influenced during the expected long transition period during which conventional and self-driving vehicles would need to interact on the road?
Honda introducing first predictive cruise control system in CR-V in Europe
January 09, 2015
Honda will introduce in Europe the first predictive cruise control system, which Honda calls Intelligent Adaptive Cruise Control (i-ACC), capable of foreseeing and automatically reacting to other vehicles cutting-in to the equipped vehicle’s lane.
Based on extensive real-world research of typical European driving styles, Honda’s Intelligent Adaptive Cruise Control (i-ACC) uses a camera and radar to sense the position of other vehicles on the road. It then applies an algorithm to predict the likelihood of vehicles in neighboring lanes cutting-in by evaluating relations between multiple vehicles, enabling the i-ACC-equipped vehicle to react quickly, safely and comfortably.

Jaguar Land Rover developing transparent pillar and ‘follow-me’ ghost car navigation
December 15, 2014
Jaguar Land Rover has launched a research project to develop technologies that will offer drivers a 360˚ view out of their vehicle (“360 Virtual Urban Windscreen”), uninterrupted by the pillars that support the roof. The company is also exploring “Follow-Me Ghost Car Navigation”, which uses a “ghost car” projected in front of the car for a driver to follow, aiding navigation on busy urban roads.
With “360 Virtual Urban Windscreen”, a screen would be embedded in the surface of each pillar inside the car and would take a live video feed from cameras covering the angles outside the car usually obscured in the blind spots created by the A, B and C-pillars. Pedestrians, cyclists and other vehicles would be visible all around the car—and by combining the transparent pillars with an advanced high quality Heads-Up display, the movement of other road users could be highlighted to the driver with an on-screen halo moving across the car’s virtual windshield.
DOT and Battelle release findings and lessons learned from V2X Transit Safety Retrofit Package project
December 13, 2014
The US Department of Transportation (DOT) and Battelle have released the latest findings and lessons learned from the Transit Safety Retrofit Package (TRP). The TRP project aimed to design and develop safety applications for transit buses that can communicate using vehicle-to-vehicle as well as vehicle-to-infrastructure connected vehicle technologies for enhanced transit bus and pedestrian safety.

Toyota bringing vehicle-infrastructure cooperative systems to some new models in Japan in 2015
November 26, 2014
Starting next year, some of Toyota Motor Corporation’s new models will be compatible with advanced vehicle-infrastructure cooperative systems that use a wireless frequency reserved for Intelligent Transport Systems (ITS). This compatibility will be offered as an option for the “Toyota Safety Sense P” active safety package that will be made available in 2015 on select new models sold in Japan.
The systems will use the dedicated ITS frequency of 760 MHz for road-to-vehicle and vehicle-to-vehicle communication to gather information that cannot be obtained by onboard sensors. At intersections with poor visibility, information about oncoming vehicles and pedestrians detected by sensors above the road will be conveyed via road-to-vehicle communication, and information about approaching vehicles will be conveyed via vehicle-to-vehicle communication, with audio and visual alerts warning drivers when necessary.

Ford will roll out new Pre-Collision Assist with Pedestrian Detection system in Ford and Lincoln vehicles globally
October 23, 2014
Ford Motor Company is introducing a new driver-assist system that can reduce the severity of or even eliminate some frontal collisions involving vehicles and pedestrians. Pre-Collision Assist with Pedestrian Detection will debut as available technology on the 2015 Ford Mondeo on sale in Europe this year. (Earlier post.) It will then roll out to other Ford and Lincoln products around the world.
Pre-Collision Assist with Pedestrian Detection uses radar and camera technology to scan the roadway ahead and, if a collision risk with a vehicle or pedestrian is detected, provides a warning to the driver. If the driver does not respond in time, the system can automatically apply up to full braking force to help reduce the severity of or even eliminate some frontal collisions. Pre-Collision Assist may help drivers avoid rear end collisions with other vehicles at all speeds, while Pedestrian Detection can help the driver avoid pedestrians at lower speeds—both may reduce the severity of forward collisions or even prevent certain forward collisions.

|An LED warning light on the A-pillar on the co-driver’s side and an acoustic warning alert the driver to an impending collision. Click to enlarge.|
Collisions when turning corners are among the most common and most serious types of accidents associated with trucks and unprotected road users. To address this, Mercedes-Benz is developing a Blind Spot Assist system for its heavy-duty trucks. The system, which utilizes a radar sensor monitoring the area next to the co-driver’s side of the truck, reliably warns the driver about dangers when turning corners in critical situations with restricted vision.
The system also takes into account the tractix curve of the semitrailer and therefore also warns if there is a danger of a collision with stationary obstacles such as traffic lights or street lamps. It also supports the driver when changing lanes.

August 04, 2014
|VTTI test display for adaptive road signs. Click to enlarge.|
Researchers at the Virginia Tech Transportation Institute (VTTI) are in the early stages of investigating the development of adaptive stop and yield traffic signs. The concept is to replace conventional roadside stop and yield signs with an in-vehicle display that would automatically alert the driver of what actions to take, if any. If no other car is present at the intersection, the driver would be allowed to pass through and go on—i.e., without halting before proceeding.
Alexandria Noble is spearheading the proof of concept adaptive stop-yield study with funding from the US Department of Transportation and under direction of her adviser and project manager, Thomas A. Dingus, the institute’s director and an endowed professor of civil and environmental engineering at Virginia Tech. Noble is the first student in the newly launched Human Factors Transportation Safety Graduate Certificate Program, led by the transportation institute.

DRIVE C2X presents results of large-scale connected vehicle field testing in Europe
July 16, 2014
In Berlin, the DRIVE C2X consortium is presenting the results of the field operational tests (FOTs) on vehicle-to-vehicle (V2X or C2X) and vehicle-to-infrastructure (V2I or C2I) technologies (collectively V2X or C2X) in Europe. (Earlier post.) With 34 partners, 13 support partners and a €18.5-million (US$25 million) budget, the three and one-half year DRIVE 2CX project, coordinated by Daimler, was intended to lay the foundation for the roll-out of vehicle-to-X cooperative systems in Europe.
Previous projects such as PReVENT, CVIS, SAFESPOT, COOPERS, and PRE-DRIVE C2X showed the feasibility of safety and traffic efficiency applications based on C2X communication. DRIVE C2X went beyond the proof-of-concept and addressed large-scale field trials under real-world conditions at multiple national test sites across Europe. During the project, more than 750 drivers tested eight safety-related functions of cooperative functions.

Ford and Intel demonstrate in-car personalization with perceptual computing; Project Mobii
June 26, 2014
Ford and Intel are researching new opportunities for the connected car, including giving drivers the ability to remotely peer into their car using a smartphone, or a vehicle that could identify its owner using facial recognition software. The joint research project, called Mobile Interior Imaging, or Project Mobii, explores how interior-facing cameras could be integrated with sensor technology and data already generated within and around the vehicle to create a more personalized and seamless interaction between driver and vehicle that transforms the driving experience.
The Mobii research, which was showcased during the Go Further with Ford 2014 Trend Conference as part of the “Big Data” track this week in Dearborn, was a collaboration between Intel ethnographers, anthropologists and engineers alongside Ford research engineers. Mobii incorporates perceptual computing technology (now named RealSense by Intel) to offer a more enjoyable and intuitive vehicle experience.
Google focusing autonomous driving development on mastering city street driving; patents piling up
April 29, 2014
Over the past year, Google has shifted the focus of its autonomous vehicle project onto mastering city street driving, according to Chris Urmson, Director, Google Self-Driving Car Project. (Urmson was the technical team leader of the CMU team that won the DARPA 2007 Urban Challenge, an autonomous vehicle race.)
Google’s autonomous cars use video cameras; 4 radar sensors (front, back, left, right); a laser range finder (Velodyne HDL-64E LiDAR) to “see” other traffic; and a GPS as well as a wheel encoder and very detailed road maps to determine the precise location of the vehicle. Google says that its autonomous vehicles have logged nearly 700,000 autonomous miles (1.13 million km) over the four years they have been on the road. Since its last pubic update in 2012, Google said that it has logged thousands of miles on the streets of Mountain View, California, Google’s home.
LMU study finds 20% of gases from combustion of R1234yf MAC refrigerant consist of highly toxic carbonyl fluoride (correction and update)
April 11, 2014
Chemists at Ludwig Maximilians Universität München report that 20% of the gases produced by the combustion of R1234yf—the approved low global warming potential refrigerant for mobile air conditioning (MAC) systems, the adoption of which has met with resistance from German automakers (earlier post)—consist of the highly toxic chemical carbonyl fluoride.
Carbonyl fluoride is structurally related to phosgene (which contains chlorine in place of fluorine), which was used as a chemical weapon during the First World War. Kornath and his co-workers have just published the results of their investigation in the journal Zeitschrift für Naturforschung B.
Tesla adding underbody triple shield system to Model S to reduce risk of battery fires caused by impacts
March 28, 2014
In an effort to reduce further the already low risk of a Model S battery fire resulting from impact with road debris, Tesla Motors is outfitting new Model S cars (as of 6 March) with an underbody triple shield system consisting first of an aluminum bar; then a titanium shield; and finally a shallow angle solid aluminum extrusion.
Tesla will also retrofit the system, free of charge, to existing Model S cars upon request or as part of a normally scheduled service, wrote Tesla Motors CEO Elon Musk in a post on the Internet publishing site Medium. The action comes as an additional Tesla response in the wake of the two widely-reported Model S collisions in 2013 that resulted in underbody damage that led to car fires. Tesla had earlier provided an over-the-air software update to increase the default ground clearance of the Model S at highway speeds, thereby also reducing the odds of a severe underbody impact.

|When the test car detects an icy or slippery road patch, the information is relayed to other vehicles that are approaching the slippery area. The information is also sent to the road administrator. Click to enlarge.|
Volvo Car Group, the Swedish Transport Administration (Trafikverket) and the Norwegian Public Roads Administration (Statens Vegvesen) are joining forces in a pilot project in which road friction information from individual cars is shared within a cloud-based system. The real-time data about slippery patches on the road are used to warn vehicles nearby, at the same time as it contributes to making winter road maintenance more efficient.
When the Volvo test car detects an icy or slippery road patch, the information is transmitted to Volvo Cars’ database via the mobile phone network. An instant warning is transmitted to other vehicles that are approaching the slippery area, making it possible for the drivers to take immediate action to avoid a critical situation.
CEN and ETSI deliver first set of standards for Cooperative Intelligent Transport Systems (C-ITS) in Europe
February 18, 2014
Standards organizations CEN and ETSI recently confirmed, at the 6th ETSI workshop on ITS in Berlin, that the basic set of standards for Cooperative Intelligence Transport Systems (C-ITS), as requested by the European Commission in 2009, have now been adopted and issued. The Release 1 specifications developed by CEN and ETSI will enable vehicles made by different manufacturers to communicate with each other and with the road infrastructure systems.
When they have been applied by vehicle manufacturers, the new specifications should contribute to preventing road accidents by providing warning messages, for example about driving the wrong way or possible collisions at intersections, as well as advance warnings of roadworks, traffic jams and other potential risks to road safety. This vision of safe and intelligent mobility can be achieved by utilizing wireless communication technologies to link vehicles and infrastructure and identify potential risks in real time.
NHTSA awards Virginia Tech Transportation Institute $1M for V2V framework project
February 14, 2014
Following a US Department of Transportation decision to move ahead with require vehicle-to-vehicle (V2V) communication technology for all cars and light trucks on the nation’s highways (earlier post), the National Highway Traffic Safety Administration (NHTSA) has awarded the Virginia Tech Transportation Institute (VTTI) a $1-million follow-on to a $3 million project managed by the transportation institute.
The goal of the project is to design, to test, and to disseminate the initial recommended framework that controls how motorists receive communications—traffic warnings, the too-close approach of another vehicle, weather warnings, or text messages—while driving. Focus will be placed on the communication’s format, visual or audible, and the order and timing of such messages.
