The Safe Road Trains for the Environment (SARTRE) Project is a current innovation aiming on making trips on the road . While legislation is not fully on board with the concept as regulations are still being put in the works, I would say that the practicality of the road train is just something that would be extremely beneficial towards changing the way people do roadtrips. Speeding is constantly regarded as a factor in motor vehicle accidents, and the SARTRE Project works to elimitate the driver speeding as the lead vehicle would be following regulations, and thus leading the following cars to the destination in a more safe manner.
A breakdown of some of the benefits of this vehicle integration includes:
-Safety- With the lead vehicle taking the motions into account, those following would be able to relax and add productivity to the trip as well.
-Environment- With the cars following a uniform pace, the emissions would be at around twenty percent less than if separate.
-Traffic- With smoother traffic flowing in and out, congestion on major roadways would be reduced.
With more benefits on the horizon as the project becomes more tuned towards an ever growing technogical foundation, the possibilities for potential application is countless for this. Currently tested under Volvo Motors, one use that could be seen with this applied is for moreso of the commercial sense. With tractor trucks logging miles after miles on these roadways, with the safety and efficiency increased with this technology, business and drivers benefit from this inter-vehicle comminication.
Overall while current laws and regulations have to be adapted towards putting this project on the road, it should become a sight on roadways within a decade’s time.

That is honestly a really awesome idea. I was kinda confused at first because I wasn’t aware that the cars would be automatically driven and I thought it was pointless, but then I watched the video and it cleared some things up. I still have other questions that probably don’t have answers yet, but would there be an extra fee to be apart of this road train or would each person simply have to pay for the gas being used? And another thing, does each car simply mirror the same exact movements as the person driving the truck?
In the video they said that it was safe and that the technology was still going through tests but I feel like this would be really hard to use in real life. There are so many external factors going on that could mess up the road train such as normal cars colliding and messing up the train line and the fact that the head truck driver would have the responsibility of multiple cars trailing behind. It’s an awesome idea though and I hope they get the kinks worked out!
