In american freeways why are there carpool lanes? what is the function of that?

The major reason states build carpool lanes is to decrease congestion on the local lanes. Putting one or two passengers in a car decreases the volume of cars required to move those people by 50 67%. The dedicated lane lets drivers to avoid people cutting in and out of the lane, more decreasing speed.

Not all carpool lanes let easy on/off and that's by design. In Houston, once you get in an HOV lane, you are stuck in it till you get to an exit point, which does not match to highway exits.

Overall, HOV lanes let for quicker ingress/egress of greatly congested regions.

It's an incentive to get people to carpool and decrease the amount of traffic that's out on the roads throughout rush hours. usually Americans drive with just one person per car and the only time many people ride together is when it is a family.

I believe they don’t have real function other than to make people think it is a opportunity to drive in the "Carpool or HOV" lanes and help advertise carpooling.

The Government is trying to push people to drive with more than one person in the car. Too many people driving the same freeways and when you look, you notice that nearly every car has only one person in it. if you have two or more people in your car you may be able to use the Diamond lane. there's lots less traffic in this lane and when the freeway is backed up it still is usually moving. This makes people want to have someone else in the car just to bypass the traffic jam.
Lets face it. to many cars. to many people.

The Government is trying to save Gasoline that way, by to get people to use the carpool lane. Also they're trying to cut down
the amount of pollution in the Air. by to get less cars off the Road.

Carpool lanes were intended so the public can share car rides with one another, causing less cars and pollution for the area. The hypothesis is: if two or more work in the same locale, traffic congestion will lessen if they ride togethr.

i think the biggest reason is that those people are all going to work. the separate lane makes that drive quicker, and less probably to get a traffic jam. it is also the right lane, allowing them easier access to exits. carpools have many stops, so they can get on and off the freeway easier. as well, there can be some discount for carpoolers in states where there are toll roads.

all of these things are to support carpooling. doing so lessens emissions, saves gas, saves wear on the roadways and puts that many less cars on the road to congest it. all of they are desireable, particularly in big cities

This is to support car pooling.

The only vehicles that may use those lanes are those with more than some # people in the car.

The more that people car pool, the less cars in the traffic, so congestion eases up.
