In a somewhat surprising announcement guaranteed to stir up the V2V community, Anastasios Zografos, speaking in his capacity as program manager at SAIC for the U.S. Dept. of Transportation's V2V/V2I Test Bed program said that the first production vehicles with connected vehicle technology could arrive in 2014 - essentially proposing a goal of 2013 for connected vehicle technology.  Separately, an ITS representative speaking privately after giving his presentation suggested that mobile phones could serve as an alternative platform for V2X technology.

Zografos was speaking at the Connected Vehicle Proving Center event held March 16th at the Institute for Advanced Vehicle Systems at the College of Engineering and Computer Science at the University of Michigan-Dearborn.  He was speaking as a representative of the Research and Innovative Technology Adminstration (RITA) Intelligent Transportation Systems Joint Program Office which runs the Vehicle-to-Vehicle and Vehicle-to-Infrastructure Technology Test Bed.  His main mission in attending the event was announcing the availability of Test Bed 2.0 for device and application development, but the 2013 mandate announcement came at the beginning of his presentation.  Contacted after his presentation he acknowledged the likelihood of delays emerging for one reason or another, but he insisted that 2013 was the official stake in the ground for the automotive industry.

Further fleshing out his vision he described the wide range of initiatives currently being pursued simultaneously by the USDOT including additional research and deployment plans as well as safety pilots.  But the announcement made clear that auto makers will be asked to deploy V2V/V2I modules based on Dedicated Short-Range Communications (DSRC) standards and also called Wireless Access in Vehicular Environment (WAVE) ahead of any supported infrastructure deployments, which will come later in a piecemeal manner over an extended period of time.

Applications highlighted by Zografos include:

Probe Data Services - for gathering vehicle positioning and sensor data to be communicated to back office servers via roadside equipment (RSEs);

Signal PHase and Timing (SPaT) Services - for integration with traffic signal controllers to better synchronize traffic with traffic light phases;

V2I and V2V Communication Services - for Internet access and safety message broadcasting.

But maybe the focus on DSRC and the rush to implement is ill-considered. An ITS representative said that standards-setting bodies in the V2X community are increasingly recognizing the power of mobile phone technology generally and Bluetooth in particular as ad hoc alternatives to what is perceived in the automotive industry as expensive embedded solutions.  The USDOT may be starting to throw its weight around on the V2X DSRC front, but the ITS world is finally opening its eyes to an answer to the connected vehicle proposition that resides in most driver's pockets and purses.

Implications:

Much work remains to bring V2X technology to the marketplace in the U.S. and elsewhere around the world.  But the statements from SAIC as a representative of the USDOT, clearly suggest that V2X technology may be closer to coming to market than previously perceived.  An important note is the growing recognition in the V2X community of the critical role of mobile phones as a connectivity technology available as an ad hoc solution for vehicle connectivity.  James Barbaresso, vice president, national ITS practice leader for HNTB, speaking on behalf of ITS World Congress 2014, noted that mobile phone data connectivity is being tested to provide many of the same benefits of V2X technology.  In fact, the industry may see fit to provide for the integration of mobile phone and DSRC signaling solutions to achieve the greatest possible benefit to drivers and the local and federal authorities seeking to make driving safer and more efficient.

In a side conversation after his presentation one ITS representative suggested mobile phones might even serve as an alternative to the DSRC technology long-preferred by the industry. The bottom line for car makers is that V2X developments are moving swiftly toward an on-board mandate.  The pressure of that mandate will help focus the attention of all constituents.  Let the lobbying begin.

IntelliDrive, the USDOT program intended to create intelligent highways, stands at the crossroads of major funding and deployment decisions but may be overlooking a solution capable of realizing the smart roadways dream in the twinkling of an eye – relative to current timelines. To do so, though, may mean setting aside, for now 5.9GHz DSRC technology in favor of a technology most recently associated with bad driving behavior. Smartphones and the cellular network hold the key to the deployment of wireless systems and services capable of revolutionizing automotive safety and achieving the dream of safe connected highway systems. This goal can be achieved through opt-in solutions that provide for the sharing of device data and could serve as a transitional technology between existing systems and the DSRC technologies not likely to be deployed for another 5-10 years. Alternatively, the government could step in with its regulatory and legislative powers and mandate the provisioning of cellular data transmissions for connected vehicle communications. (Such a scheme was described to me by an ITS America member at the recent Distracted Driving event in Washington, DC. The executive asked to remain anonymous because his proposal may actually be at odds with the short-term interests of his employer.) So cellular technology, which is already part of the IntelliDrive vision along with DSRC and Wi-Fi, can be used as a transitional alternative to DSRC on a voluntary or involuntary basis. (DSRC is universally preferred for safety applications because of its low lacency.) On the involuntary side, concept is to require smartphones to share their location data and to be used for the reception of targeted emergency or road sign messages. The proposition involves a monthly charge to the subscriber of approximately 10 cents – not unlike the current eight-cent charge for mandated 911 calling on mobile phones – to cover the cost of the first 500Kb of monthly data use on the phone for ITS purposes. (It is worth noting as an aside that Wi-Fi technology has already been pioneered – notably by Dash Navigation – as a V2V technology for communicating highway and traffic conditions. With Wi-Fi technology proliferating on smartphones it will not be long before this same capability emerges in the handset space.) Confronted with this opportunity opponents are quick to note the privacy and liability concerns associated with cellular (and Wi-Fi) technology and the need for, at the very least, an opt in mechanism. The bottom line is that these concerns are not insurmountable and a mandated system is feasible. Opening up a data channel on all phones for location data and automatic crash notifications (transmit) and in-vehicle messaging (receive) will open the door to wide adoption of telematics technology and achieve the goal of connecting vehicles to the infrastructure, in-vehicle messaging and to emergency services. The business models to support the service rationale are not unlike those for RDS-TMC, 911 and 511 services, which means this solution is designed to be low cost but still requires some third party support from private companies. The barriers to be overcome are numerous and include – inter-carrier cooperation, the creation of a data clearinghouse for processing and filtering data, and the creation of a broadcast mechanism most likely via multiple private entities. Achieving comprehensive deployment on mobile phones will also require federal legislative and regulatory action. Because the mobile phone-based system will pay for itself while also taking advantage of ubiquitous handset technology and the cellular network it has massive advantages over the proposed DSRC-based system. The 5.9GHz DSRC technology will require BOTH auto maker support for an added module and antenna AND a huge deployment of transmitters and receivers along roadsides and the corresponding data processing infrastructure. DSRC is inevitable, but why must the driving public wait for a solution that will save lives. If the mandated approach is too onerous, then it is more or less left to private enterprise to implement their own prove networks along the lines of Waze and the CloudMade communities which are multiplying around the world. These emerging networks have the capability to bring these services to market almost immediately. More importantly the proliferation of OBDII connections (admittedly using wireless communication protocols claimed by Hughes Telematics) means smartphones are also capable of communicating vehicle sensor and camera data, further enhancing the value of the proposed systems. The proliferation of low-cost sensor and camera systems means there is a wealth of available inputs such a system can put to work to enhance safety, reduce congestion and hazardous driving conditions, and improve the overall driving experience. In fact, the proliferation of smartphones and inexpensive cameras and sensors are rapidly combining to mitigate the demand for the IntelliDrive DSRC vision. Consumers and industry representatives may discover after the implementation of a smartphone based network sharing vehicle and sensor data and communicating traffic conditions, the incremental enhancement of DSRC deployment is unnecessary. The concept also suggests that those car makers with embedded systems should be able to gain an advantage from having more direct and complete control of the user experience. And those car makers with existing probe networks will gain the first-mover advantage of having a larger volume of inputs to process for the benefit of their subscribers. Facilitating the implementation of this vision will be the rapid development and deployment of handset connectivity technology. From terminal mode to Delphi’s D-Connect and Apple’s iPod out, the technology is rapidly falling into place – alongside OBDII communications and sensor proliferation to facilitate the communication of traffic and other urgent messages to primary and secondary displays in the car. In fact, the mobile phone industry is facing the prospect of a handset FM receiver mandate that will create yet another pathway for communicating information into the vehicle either via the on-board radio or via the mobile phone. The handset FM mandate is intended mainly for the transmission of emergency alerts, but will also enable regular FM transmissions. Conclusion: The concept of using mobile phones and cellular technology to supplant or serve as a transitional solution to the proposed DSRC network for V2X communications is radical and lacks an advocate as a mandate but is already emerging as a voluntary solution in the form of discreet smartphone applications and related user communities. The mandate path is likely to die since the very companies that most recognize its value – those with currently deployed embedded telematics systems  - have the most to lose from its implementation. Other market participants such as content and applications providers and even telecommunications carriers may also be opposed to a mandated proposition as it threatens existing business models and relationships. But all parties are beginning to recognize the mobile phone as the key to solving multiple safety challenges in the vehicle. Whether anticipating hazardous intersections (Global Mobile Alert) or sharing probe data (Waze, TrafficTalk) the smartphone has established its credentials as a safety device. The phone also benefits from the support of a rich developer community rapidly moving smartphone technology into realms not previously foreseen.

Driving has never been safer, with vehicle crash-related fatalities at an all time low in most areas of the developed world. But public authorities are pushing for zero fatalities and these efforts are helping to bring enhanced safety technologies to the market through a combination of embedded and off-board solutions. Still, not everyone agrees on how to make cars safer. The latest high-profile debate revolves around distracted driving and mobile phone use. Some argue that hands-free interfaces help drivers by allowing them to keep their hands on the steering wheel and their eyes on the road while interacting with their mobile phone. Others believe that no mobile devices should be in the car at all since they represent a driver distraction. Acknowledging the role of distraction (a suddenly loaded noun with many potent and potential meanings) in accidents, a purist might argue for an in-vehicle experience bereft of distracting displays. In this context, a shift to head-up display technology might make more sense than in-dash displays, MMI/i-Drive-type interfaces and touch screens. Even voice interfaces might take a backseat in this scenario. Companies such as General Motors and Microvision are among those leading the way down the head-up path. In an environment where regulators want drivers’ eyes on the road it is the only logical way to go. But the industry and consumers may not be ready for this leap. And with so much industry focus on in-car mobile phone use as part of the U.S. Dept. of Transportation’s Distracted Driving Initiative, the head-up display conversation is likely to be deferred, ignored, or simply drowned out. (It is important to note that head-up displays are no longer available from Buick or Cadillac, as recent dealer visits have confirmed. BMW is now the leader in head-up display technology in North America. The technology remains expensive and, generally, a special order item.) The USDOT’s Distracted Driving Initiative will see its second summit conference this year in Washington, DC, September 21st. The goal of the event is to raise awareness of distracted driving resulting from in-car mobile phone use generally and texting in particular and to seek solutions to the problem in a public forum. Ford Motor Company stands in the eye of this storm with its high profile Sync hands-free system and the MyFord Touch upgrade arriving later this year. Ford is carrying the flag for hands-on-the-wheel/eyes-on-the-road driving in a struggle with Dept. of Transportation director Ray LaHood, the National Safety Council, the American Automobile Association and Oprah Winfrey, all of whom oppose the use of mobile devices in cars under any circumstances. (Ophrah may have changed her tune recently to allow for hands-free interfaces.) The debate raises fundamental questions regarding safety systems and automotive interfaces. Distracted Driving campaigners implicate the two-second glance to an iPod, iPhone or other mobile device as the culprit in more than a million roadway accidents (http://bit.ly/6uP3wu). All parties agree that there is a problem, but disagree on its nature and magnitude. There is also definite disagreement on the solution. And if a two-second glance is the culprit, what about all of those OTHER two-second glances in the car? Ford’s eyes-on-road-hands-on-wheel message could not be clearer and the company has backed up its position with its own research along with the results of both independent and industry-sponsored studies. Ford’s Sync and the unfortunately named MyFord Touch (which is intended mainly for voice, not touch, interfacing – in spite of the touch screen) represent the solution to a long-standing problem. Driver Distraction has been an issue confronting automobile designers from the very earliest days of the industry. The emergence of car radios in the 1930’s, for example, led to the introduction of push button channel selection to ease the distraction of locating stations with a dial. Multiple international standards-setting bodies and industry associations have long ago specified the appropriate viewing angle (30 degrees) of dashboard displays to minimize eyes-off-the-road time.  Designers regularly do battle over the question of touch screen or no touch screen, debating the finer points of changing focal lengths and distraction. Audi delved deeply into this issue before launching its touchpad interface. Yet all of the i-Drive and MMI-type interfaces still require a glance at a display in the car. Strangely, no one in the industry seems to be taking this distraction debate to its logical conclusion. If a two-second glance to an in-vehicle display is a source of potentially fatal crashes, the industry needs to be taking an entirely different direction. If displays of all kinds are the problem, then let’s do away with on-board displays completely. At the very least the industry should commence an initiative to explore a shift to head-up displays. But, wait, before we undo more than a century of HMI refinement let’s go back to the beginning. Highway fatalities are at an all-time low throughout the developed world and are especially low when indexed against the extraordinary increase in miles driven. During this time of declining road fatalities smartphone penetration has grown at an equally extraordinary pace. Smartphones, therefore, are not an obvious source of highway fatalities, but anecdotal evidence suggests these devices are not blameless. Ford is an interesting organization to find at the nexus of the debate. Not only has the company led the way in bringing voice interfaces into the car for safe operation of mobile devices, it has also pioneered the safe implementation of those interfaces. Examples of safe voice implementation by Ford: #1 Software development kit (SDK) enforces Sync constraints such as no keyboard entry or video while moving and list length limitations. This “policy management” layer is also being implemented within Apple’s iPod out, Delphi’s D-Connect, and Nokia’s Terminal Mode (http://bit.ly/b22buN), among other solutions. #2 When a vehicle is in motion, Ford locks out features and functions such as pairing a Bluetooth phone, editing or adding contact info, POI reviews, detailed sports scores or movie times, manual destination entry, all demo modes, keying in or editing messages, Internet access, external keyboard, editing settings, setting up short-cut buttons. #3 Ford limits list lengths (contacts/recent calls/POIs), the number of canned text responses and Sirius Travel Link information when the vehicle is moving. Ford’s recommendations for mitigating distracted driving include: #1 Passage of Jay Rockefellers’ anti-texting Senate Bill (http://bit.ly/aLMKL4) providing incentives for states to pass anti-texting legislation; #2 Primary enforcement of existing mobile phone bans; #3 Limiting mobile phone use for holders of graduated driver’s licenses – ie. teens; Ford also offers its MyKey technology for parents to limit vehicle speed, stereo volume etc. for teen drivers. #4 Education/public awareness campaigns – ie. Ford’s Driving Skills for Life (http://bit.ly/8TcMpn); #5 Elevate Alliance of Automobile Manufacturers’ “Driver Focused Telematics Guidelines” to regulatory status (http://bit.ly/ddCpRd); #6 Increase funding for research – handheld vs. voice; relative risks of distractions including cognitive; and review real-world driver compensation behaviors. The embedded, policy management side of Ford’s smartphone-based effort has been Volvo’s IDIS workload management solution. Not surprisingly, Ford is working on similar on-board solutions that take into account driving conditions and vehicle status based on messages on the vehicle CAN network including stability control and windshield wiper engagement, speed, and traffic. There is a small irony in Ford’s sale of Volvo given Volvo’s leadership in vehicle safety. The timing was rendered especially poignant given the National Highway Traffic Safety Administration’s shift in the middle of last year toward a focus on preventing rather than simply surviving accidents (http://bit.ly/9L6MFi). Volvo has been a leader in bringing technologies to market that anticipate and attempt to avoid accidents. IDIS (for Intelligent Driver Information System) is intended to shut down distracting in-vehicle functions – such as mobile phone access or even warning lights - in the presence of hazardous driving conditions – intersections, overtaking etc. IDIS takes into account such driving circumstances as acceleration, speed reduction, turn signal indicators, steering wheel angle, reverse gear engagement and infotainment controls. Its primary output is to delay/manage incoming calls and vehicle alerts. The next step for IDIS will be the integration of map data along the lines of map-based advanced driver assist system designs from Navteq (with partners Magneti Marelli and STMicroelectronics) and Intermap (Visteon). The integration of map data with vehicle safety systems will allow for curve over-speed warnings or pro-active braking when approaching sharp turns. One can expect more solutions to block mobile phone access – as in the case of Global Mobile Alert – in the proximity of hazardous intersections, school zones or rail crossings. Strategy Analytics research shows that consumers want safer cars. Recent Strategy Analytics surveys reveal high consumer interest in night vision, pre-crash safety, adaptive front lights, blindspot detection, adaptive cruise control, driver attention monitors, lane departure warning, parking assistance, V2V communication and automatic speed limiters. The challenge of course, is getting consumers to pay for these technologies. This reluctance to pay creates the conditions for Federal mandates. And Federal mandates are likely to change the public’s perception of safety from an exploding airbag to a pre-emptive braking experience. Auto makers are already responding to this shift. Infiniti, Toyota, Mercedes-Benz, Opel and Volvo are all actively touting active vehicle safety systems with the best and most advanced of these taking driving context into account. These systems are also increasingly taking distraction, inattention and even driver fatigue into account. Conclusion: In an ideal world, there would be no distracting displays inside the car to divert the driver’s attention from the eyes forward concentration on the driving task. In this ideal world, head-up displays would be widely deployed and traffic fatalities would be continuing their downward trajectory. We do not live in an ideal world. Therefore, everything else in the world of automotive HMI is a compromise. In the context of that compromise, vehicle systems that take into account driving circumstances and device connectivity are preferred to those that do not. This means that systems and devices – Apple’s iPod out, Nokia’s Terminal Mode, Delphi’s D-Connect – that provide a contextual policy management layer will be in demand. More importantly, with NHTSA shifting its focus to crash avoidance, perhaps the entire automotive industry will begin to rethink what safety is and what safety means. And when it comes to distracted driving, there will hopefully be a federal and industry embrace rather than a rejection of technological solutions such as hands-free interfaces.
