Silicon Valley technology could be key to connect cars for safer driving
Nov 02, 2012 (San Jose Mercury News - McClatchy-Tribune Information Services via COMTEX) -- While Google's (GOOG) self-driving car is getting heaps of attention, a lesser-known effort that would employ Silicon Valley technologies to make regular automobiles safer is fast gaining traction.
Under the "connected vehicle" program being developed by federal and state officials, cars, trucks and buses bristling with gadgets would wirelessly communicate with each other as well as with traffic signals, pavement-embedded sensors and other road equipment.
Drivers then would get automatic warnings about everything from icy bridges and accidents in their paths to cars racing at them through red lights and lane changes they should avoid because another vehicle is next to them.
The National Highway Traffic Safety Administration is due to make key decisions next year about how to proceed and authorities expect connected-vehicle devices to start showing up in cars by 2019.
"This is going to be a very big deal," said Greg Larson, chief of the office of traffic operations research at the California Department of Transportation, which has been studying the concept. Calling the government's timetable "very realistic," he added, "I don't see any technical challenges in getting this done." Some carmakers already have equipped vehicles with gadgets to alert drivers to potential collisions.
But those devices only spot nearby hazards, among other limitations. And while California has approved testing of so-called autonomous vehicles -- like those Google is working on -- getting cars to safely drive themselves is complicated.
Google declined to discuss the subject. But Steven Shladover of California Partners for Advanced Transportation TecHnology, a research group at UC Berkeley, said a big challenge in designing self-driving cars is to make software that can nimbly respond to unexpected events.
"This will require a very large research and development effort," he said. But if those vehicles could be relegated to their own special-purpose lanes, he added, "the technical problems become much less daunting." No matter how autonomous cars are designed, however, "we think they could work better when they are connected" with other vehicles and roadway devices, Larson added.
By being electronically alerted about hazards, transportation officials believe, drivers could slow down or otherwise maneuver to avoid them. And if an accident did happen, they say, it might be possible to instantly relay key information about the mishap to emergency personnel. That could include where it occurred, how fast the vehicles were traveling, if air bags were triggered and the passengers' medical histories in case they were injured.
Another option being considered is to enable the system to warn blind pedestrians when it's unsafe to cross streets.
Although details on how this would work have yet to be decided, connecting cars, stop lights, highway cameras, pavement sensors and other traffic-related gear would likely require an array of Silicon Valley products, including microchips, routers, servers and software.
It's unclear how much of that would need to be installed along streets and highways. Some experts believe it would have to be extensive, while others contend cars could be made smart enough to spot dangers and warn other vehicles in their vicinity -- possibly via cellphones -- without needing much information from roadway equipment.
Potentially troublesome issues to be resolved include how to warn drivers without dangerously distracting them, how to prevent hackers from disrupting the system and how to standardize the different gear that automakers and government agencies might use so it all functions seamlessly.
Another concern is what such a system might cost. Experts have been vague about that. But the tab for just upgrading the microcontroller chips in traffic signals nationwide could total more than $400 million, according to a study by the American Association of State Highway and Transportation Officials.
A Clemson University group has proposed partly covering the cost by charging businesses a fee to send advertisements to connected cars. But if the system works as intended, many experts believe, it could save money by averting most of the 6 million crashes that happen annually at a cost federal authorities estimate at $230 billion.
The project also could be a boon to some Silicon Valley companies.
Santa Clara-based Intel (INTC) "is actively working with the auto industry to make the connected car vision a reality today," said the chipmaker's spokeswoman Krystal Temple. Intel recently created a $100 million fund to study connected-car technologies, opened an automotive engineering site in Germany and one of its vice presidents sits on a federal advisory committee for the proposed system.
Another local company helping car companies and others plan for the effort is Cisco Systems (CSCO), which makes routers and other information networking gear. The concept could represent a $2 billion to $6 billion revenue opportunity for the San Jose company, according to Helder Antunes, Cisco's managing director of smart connected vehicles.
Because of the social benefits that would result from linking motorists, "this will accelerate faster than most people think," he said. "It's coming."
