Road Trains Could Allow Driverless Green Travel

The idea of self-driving vehicles has been getting increasing attention on several fronts. Google's self-driving car is perhaps the most widely publicized example, but other options are under development at various stages. Volvo is working on a different approach, with cars that are not completely autonomous, but that can safely follow others in a close formation known as a road train.

In a road train, vehicles equipped with wireless connectivity and viagra online sales control equipment will be able to where to order cheap viagra follow other vehicles in close formation, with a lead vehicle being driven by a human driver. Computers and sensors will monitor the convoy, and automatically follow the lead vehicle with safe clearances. Once a vehicle is part of a road train, the driver can can switch their attention to other things.

Road trains would offer a number of benefits that are beneficial to the environment as well as to drivers.

Fuel mileage will improve, as vehicles stay at the same speed (acceleration reduces efficiency). Cars can safely drive more closely to one another, and will benefit from lowered wind resistance. With groups of cars moving at predictable speeds, congestion will improve. And the stress of order generic cialis the viagra soft tablets daily commute will be alleviated, with time in the car to read or relax.

The Volvo system has been undergoing testing for the past several years. A video presentation from Volvo shows vehicles operating on a test track to demonstrate the workings of this system.

I'm pretty sure google's system is this (self-driving cars communicating with each other for more reliable results) plus programs for other interactions involving city streets and with other user-controlled cars. This Volvo bit is the easy part.

This is incredible and interesting. I can see how it would reduce emissions by having all the cars together and not varying their speeds. Yet what happens if someone has to go to the bathroom or stop for lunch? Could you get off the road train easily? Lol.
What about the only here buy discount levitra online other drivers

It seems like if one reckless driver moved into their space it would cause a multiple car pile-up.

Why would anyone on the freeway want to sit behind a slow moving heavy vehicle. What happens if the train gets stuck behind an even slower vehicle, the train length would mean that it would have almost no chance of moving to another lane to overtake.
I wouldn't trust a Google car as far as I could throw one

Being a Google car, it would only be using 35% of its CPU resources to managing the car, the remaining resources would be used serving up advertisements and stealing the identities of your passengers.

Volvo on the other hand, are a respectable company with a long history and culture of road safety innovation.

Google? Just say no.
Seems strange but probably the future

I know this car train seems strange but sooner than we think all freeways might be like this. You'd program your car to go to a certain destination from the onramp and cheapest viagra prices without a prescription then join a "train" of cars that would be on automatic and spaced equally and going the purchasing viagra with next day delivery same speed. And then you could request to buy cialis overnight delivery get off. It'd probably reduce traffic deaths by alot actually because the unsafe drivers and speeders would have no control.

Instead of making it as convenient as a train to ride, maybe we should just build more trains and infrastructures for car renting.
Public transportation is the future, not individual.

The US might be better served to re-establish a functioning rail system using the same intent that build the national highway system across the US starting in the 1950's. I love the freedom of my car as much as the next American but Europe and Asia have managed very well with a serious rail system for cargo and personal transport. The greatest obstacle will be right-of-way's that reverted to the public and have been filled with urban development. I am sickened to observe that the good choice buy real levitra online love of purchasing levitra with next day delivery the personal transport is leading to the paving of America.

1) This seems incredibly flawed. One deer in the road and you have a massive pile up.

2) Volvo being a trusted company, yeah they only gave them selves awesome safety ratings for about 2 decades. Not saying they are not safe but why not submit to outside testing for your advertised safety ratings before it became mandatory.

3) While I like trains in Europe, studies prove that most mid size sedans are more fuel efficient than most trains per passenger; meaning it takes more fuel/energy per person for a train than a mid sized car. Imagine if you had a smart diesel or hybrid and carpooled you would kick a trains but.
I love the idea of having a car automatically draft a bus or truck for fuel savings and automation but I think a lot more studying needs to link for you buy viagra online be done and a slight revamp of our highway infrastructure.
Agrred with Bob

I share the same set of thought as mentioned by Bob in the series of comments that why would even just say back and concentrate on other work in a slow moving car.
Instead, the driver would definitely want to reach his destination ASAP and would not be interested in formating some road train.

I would really love to have this feature in a car to be able to at least multi task while driving.

Benefits are undoubtly great, I mean, it could bring some incredible order to the roads

Negatives are that this can be seen as a form of oppresion, and just imagine the criminal possiblities. Aside from satellite tracking, anything can be hacked. Imagine sitting there in your car, when suddenlly you take an unexpected course into a steep ditch. Just sayin'. I say, the benefits are too great and too easy to manipulate. There will always be somebody good enough to manipulate whatever technology is out there. Hence, crime.
Though I disagree with the problem of the pileups. Say the front vehicle was infact subjected to some kind of accident, like a crash, assuming the following cars are travelling at a safe distance, wouldn't the lead vehicle stopping cause following vehicles to discount us propecia stop behind it? Or else travelling through traffic lights and turning corners could be an issue. I'm not exactly the physics 'spert here(and I only scanned the buy cialis cannada above article and comments), but that would be my guess.
Also, things like these are unnessesary, and support two extremes of common human behaviour: 1. laziness and 2. whatever you call being too busy.
Both can lead to serious physical and mental health issues.

I do not believe this kind of technology to be suitable for the roads, but I'm certain it can be useful in other areas.

Way to go..

Sounds very very interesting to me smilies/smiley.gif. Thing of the future.
written by bluetoes591, January 25, 2013
This seems flawed to me. Now you have a string of people all at the mercy of the driving abilities of the driver of the lead vehicle. Experience on the road tells me that I can't trust anybody else driving a vehicle to do the expected or safe thing ever, so why would I trust them under these circumstances?

Forget trying to cheapest generic cialis professional make cars eco-friendly, and forget only talking about fuel efficiency while ignoring all the other environmental and social problems caused by cars i.e. habitat destruction, sprawl, etc. This is so 1950's?jetsons. Trains, public transit, and bicycles are the future.

Various automobile industries are trying to develop their techniques and approaching on inventing advanced automobile techniques. As a result self driving concept was born and it delivers positive driving experience to avoid accidents. Therefore instead of wasting our time to find a personal injury lawyer whom are liable to pay back a positive compensation for our losses why not we take advanced precautions through these self driving concept.

It is a lesson for us nothing is impossible in this world. Basically automobile sector is a changing sector by adopting new and lowest priced viagra advanced technology regularly. It is an up to dated article which is based upon electric vehicle, not only about the vehicle but also contain its services stations and a small data which is essential. It is true that all consumers’ wants are always changes according to their needs. Keeping this point in front of view all automobile sectors are continuing changes and new inventions. The automobile market is variable due to such changes and customer needs.

The evidence is overwhelming that CAFE standards result in more highway deaths. A 1999 USA TODAY analysis of crash data and estimates from the National Highway Traffic Safety Administration and the Insurance Institute for Highway Safety found that, in the years since CAFE standards were mandated under the Energy Policy and Conservation Act of 1975, about 46,000 people have died in crashes that they would have survived if they had been traveling in bigger, heavier cars. This translates into 7,700 deaths for every mile per gallon gained by the standards.
Driverless Car
written by Mike Atherton, July 20, 2013
Driverless cars or self-driving cars are really good than that of the general cars. Driverless cars are quite safe than a human operated car. In human operated car, there is chance of distract driving, but in case of self-driving car, there is no chance of distract driving. No chance of distract driving means no chance of accident. So the traveling in a Driverless car is quite safe and secure even if in crowded areas. So, I think this is a nice step to purchasing viagra with next day delivery allow the Driverless cars on the road by making it legal.

Its a very good concept for the users but how can it possible is the most important thing. Now accident got increase from the past due to the rash driving, so how can we avoid the rash driving is the most important thing, driver less car is a better thing for the people, if got some problems in the driving then it will create problem for the people.
