PopSci looks at eight technologies that will make future automotive adventures free of traffic jams, fender benders and fruitless hunts for parking spaces.
A. Traffic Probes
Taking a cue from crowd-sourced navigation on GPS-equipped smartphones, networked cars will act as probes, delivering real-time traffic, weather and accident data.
B. Cars that Never Tailgate
By roughly 2015, General Motors says, its adaptive cruise control systems will not simply adjust to slower cars ahead but will check for a lane opening and steer around cars without having to slow down. The next wireless step: "platooned" autos, linked in manageable groups to travel highways like coupled freight cars, which would save fuel, reduce pileups, do wonders for traffic jams—and free drivers from commuting drudgery. As early proof, this March GM's new EN-V concept cars—electric two-passenger urban transportation pods—will drive around a GM exhibit in Shanghai in a choreographed display of wireless automation.
C. Beacons for Pedestrians and Cyclists
Nonmotorists can join the network by carrying a simple transponder that alerts cars to their presence, fixes their location, and ensures that cars don't hit them.
D. Crash Mitigation
If a collision is unavoidable, networked cars could automatically reposition before a crash to protect occupants, such as pivoting a car to turn a deadly T-bone accident into a survivable rear-ender instead. (Mercedes's latest safety concept car already inflates metallic structures inside the doors to create a beefier barrier.)
E. Take-Charge Emergency Vehicles and Motorcycles
Ambulances will digitally broadcast their out-of-my-way signal into cars ahead or even require them to automatically slow down and pull over. Motorcycles will get a digital assist, too. People often miss them in their rearview mirrors, but to automated cars they will be as visible as an 18-wheeler.
F. Sticky Lanes
New satellites will allow cars to pinpoint their position within an inch. That "lane-specific" level of accuracy can help cars "snap to" a digitally mapped lane like a slot car on a track when a driver daydreams or falls asleep, even on the snow-covered or poorly marked roads that confuse today's lane-departure cameras.
G. Smart Intersections
You'll never see the drunk driver that's about to run the red light. But a smart intersection could save your life. Twenty percent of all crash fatalities and 40 percent of accidents occur at intersections. Smart intersections will communicate with cars, beaming them visual and audio collision warnings, and even taking direct action to slow or stop vehicles and prevent offenders from running red lights entirely.
H. Parking Lots that Talk
Many cars can already parallel-park with little or no human input. Tomorrow's networked cars and parking lots will tell each other when and where a spot opens up, saving drivers from wasting precious time and gas while circling the block. Drivers can beeline to open slots, or head to work and let the car park itself—and then call the car to come fetch them at day's end.
i like letter H. thats my ideal car to pick me up at the air port.
Oh that's cool, I just like the letter H in general. It's my favorite letter from the alphabet.
H. Opening scene to next planes/trains and automobiles.
Guy is late to get plane and chooses the auto park feature.
He gets out of the car, presses the button and realizes he left his cell phone charger in the car. He leaves his bags and runs after the car.
When he reaches the car, he tries to get into the car and gets caught up in the seatbelt and is then dragged to the parking spot.
He gets untangled, gets car charger and now spends 15 minutes walking back to the entrance looking for his bags which were left unattended.
Meanwhile the unattended bag bomb disposal unit is taking his bags to be destroyed.
The complexity of these technologies is staggering. Add to that the requirement for nearly 100% participation by vehicles( and pedestrians for "C"), and it begins to approach the impossible. Reliability and economics both work against success.
Weather, RF dead spots, and basic product failure will all impact reliability,
Economics relates to the fact a large portion of the population drives older vehicles that they struggle to maintain. The cost of these new schemes will force them into mass transit/human power(with no RF device attached).
Some of this technology may ne readily available soon. I would suggest that any implementation to a significant degree will take decades longer.
The pedestrian beacon (C) is a potential disaster. What if someone looking to cause trouble throws a few of these out on the freeway.
I have driven cars with the new technology for parallel parking and can see this types of technologies working. Using these technologies to make our roads safer will save many lives.
I am very much pleased with the contents you have mentioned.I wanted to thank you for this great article. I enjoyed every little bit part of it and I will be waiting for the new updates.
