Concept
Platoon (automobile)
Summary
In transportation, platooning or flocking is a method for driving a group of vehicles together. It is meant to increase the capacity of roads via an automated highway system.
Platoons decrease the distances between cars or trucks using electronic, and possibly mechanical, coupling. This capability would allow many cars or trucks to accelerate or brake simultaneously. This system also allows for a closer headway between vehicles by eliminating reacting distance needed for human reaction.
Platoon capability might require buying new vehicles, or it may be something that can be retrofitted. Drivers would probably need a special license endorsement on account of the new skills required and the added responsibility when driving in the lead.
Smart cars with artificial intelligence could automatically join and leave platoons. The automated highway system is a proposal for one such system, where cars organise themselves into platoons of 8 to 25.
Greater fuel economy due to reduced air resistance and by reducing the need for acceleration, deceleration, and stopping to maintain traffic flow.
Reduced congestion.
Substantially shorter commutes during peak periods.
On longer highway trips, vehicles could be mostly unattended whilst in following mode.
Fewer traffic collisions.
Vehicle to vehicle charging
Some systems have failed in traffic, as they have been hacked by remote computers, creating a hazardous situation.
Drivers would feel less in control of their own driving, being at the hands of computer software or the lead driver.
Drivers may be less attentive than usual, and they may not be able to react as quickly to adverse situations if the software or hardware were to fail.
In the event of a traffic collision with the lead vehicle, the entire platoon may be caught in a multiple-vehicle collision due to the reduced vehicle spacing.
Smart highway
An automated highway system (AHS), or smart road, is a proposed intelligent transportation system technology designed to provide for driverless cars on specific right-of ways.
