How Motorcycles Could Eradicate Traffic

Swapping cars for bikes drastically reduces traffic and emissions, according to a new study.

The Ducati Diavel. Photo by Ducati.We know that motorcycles get far better gas mileage than passenger cars and trucks, so it follows that if motorcycles replaced cars on the roads, gas consumption would decrease. But traffic would also drop significantly -- a revelation that comes courtesy of a new study by a Belgian transportation-research firm. 

Researchers used computer-modeling software to analyze a stretch of highway between the Belgian cities of Leuven and Brussels, pulling from rush-hour traffic statistics during a typical workday last May. They found that if 10 percent of cars were replaced by motorcycles, drivers' commuting times would decrease by 40 percent and emissions would drop by 6 percent. (The latter is a combination of the fact that motorcycles inherently have lower emissions and that emission rates drop as a vehicle's speed increases -- which it is wont to do when traffic lightens or dissipates.) 

Moreover, when the results were extrapolated to Belgium's other highways, the time savings for all vehicles was 15,000 hours per day. And when 25 percent of cars were swapped out for motorcycles, traffic was eliminated entirely.

The explanation for the traffic cure is simple enough. "When there is little traffic on the road, it can be expected that motorcycles will take up as much space on the road as cars," researchers wrote. "However, when the road becomes busier, and the speed of the traffic flow falls, motorcycles take up less space. Some motorcycles keep less distance from the vehicle in front or ride between two lanes." And when car traffic stops altogether, motorcycles keep moving thanks to lane splitting -- the practice of steering between rows of cars lined up in traffic lanes, which is legal in many parts of the world.

Since the study incorporated only statistics on Belgium's primary roads, its main commuter thoroughfares, there are limits to what researchers can do to predict further-reaching traffic reductions. But they speculate that secondary roads would experience a similar traffic boon: "Based on a number of partial reflections, it can be expected that the time benefit is of the same order of magnitude as that of the primary road network," they wrote, though they added that "additional research is needed to substantiate this statement."

Commenter Colleton, You clearly don't pay attention. Most consistent traffic cause is commuting. > 50% commuters (that i watch) do not carpool and do not carry spouses or kids. Also, the article doesn't say AWAY WITH CARS! It says, replace 10% = Good, replace 25% = amazing. That leaves 75% for people who NEED them, who isn't MOST people (just like SUVs)

F a ck You windows live.
To Dennis - Good except i disagree twice. Prius does get better gas mileage, but  most cars mpg is not better than most bikes mpg. Also, cost is prohibitive. A new prius runs over 20 grand, a new Kawasaki Ninja 250cc is small enough to learn on, big enough for highways, and gets 50mpg at WORST, 70mpg is reasonable. Also, learning does not take years, while being good might, being proficient enough to be safe doesn't.

It is about time some one does a full research project and confirms what most of us motorcyclist already know.
  There are a couple of points not covered like there will be an increase in crashes/deaths for a couple of years as people have to LEARN how to ride a bike, the other is an increase in racing and other illegal activities.....for a bit until people realize wheelies at 110 on the freeway ARE NOT COOL and do something about it.

  It will reduce traffic and can reduce smog. the only issue here in the U.S. is peoples love affair with cars. No matter what gets decided or enforced, people will continue to drive cars and continue to kill motorcyclist and bicyclist from lack of attention,speed,messing with the radio,etc etc. If some sort of tax or reg credit comes along with this AND proper training (not the MSF) More bikes will be used I think. They are also much easier to convert to methane,kerosene,alcohol,etc etc fuels. Which means when the gasoline prices rise to 10 bucks or higher you will still be able to get around without having to rely on gasoline.

One point that must be addressed properly............fuel efficiency........motorcycles DO NOT burn cleaner or get better miles per gallon than cars.......not yet at least.....

Most bikes carry 5 gallons of fuel and only get 150 to 200 miles per tank depending on make and model. So that is between 30 to 40 mpg..........the Prius gets between 40 and 50 mpg and needs a fill up maybe once a month. A bike needs a fill every couple of days if you commute..........So lets see, a typical bike weighs 400 to 500 lbs and gets 30 to 40 mpg..........
a Prius weighs in at around 4,000 lbs and gets between 40 to 50 mpg............seems to me the car is way more efficient than the bike and the car has less emissions.
Bikes will get there but they need about 10 more years or longer if the world credit situation does not stabilize.

I'm all for more bikes less cars, however, places like Alaska or North Dakota in the winter are not bike friendly and you know that there will be regs as the local governing bodies want the money, so how to make it fair?

heyfred - Nope. I've been to NYC, Chicago, and Washington for extended periods - and rode their trains.

BECAUSE traffic was so bad on their poorly planned roads that they force you to use the trains!

Please name just one place in the world where the trains when installed, decreased road traffic.

Don't break your search engine looking - there are none.

If road miles goes up in direct proportion to population increases, traffic always decreases. (Unless you put the roads in places without actual users).

IE you have 1,000,000 people and 5000 lane miles - you go to 2,000,000 people and 10,000 lane  miles.

It's not rocket science. But many cities really don't want to end traffic. If you can get into a city easily, you can get out of it easily. So you might live outside it.

But you can't move goods on motorcycles or commuter trains/subways.

And there is no issue in the US that gets as much universal support and participation as driving.

We absolutely need many more new lanes of roads. This infrastructure is what makes business efficient and therefore competitive. Not to mention the millions of hours of wasted time, wasted fuel, and emmissions that poorly planned or underfunded roads creates.

Not if you live in Boca Raton Florida.. The old people here can not see you. I used to ride motorcycle until I got ran over by this old lady that, after hitting me, she  continue going her way not knowing she hit something... Now I drive a truck and they still can't see it...

And where exactly do the spouse's and kids go? Do you buy them all mini bikes or ride them around bitch... lined up one after the other behind you like monkeys? Its sounds all so simple and reasonable until you think about the practicality of it all. Children in side cars? motorcycles designers building family friendly rigs that can haul everybody around? And where would that get you? Back to a car i would imagine. Its simply not a feasible alternative in America that is unless they create an affordable nation wide public transportation system, city to farm, one side of the country to the other.

Belgium can extrapolate all they want, but it simply would not compensate the costs of completely changing the entire infrastructure in order to accommodate everyone else besides single commuters,which in this country is probably far less than half of the people on the roads on a daily basis.

You can tell Ryan in Texas isn't a city boy. There are plenty of studies showing traffic increases in line with road construction. You cannot build your way out of a city's traffic problems. Atlanta's beltway is up to 29 lanes wide on the north side of town, and the connectors nearly as wide. It still stops during rush hour. I've ridden the subways in NY, Chicago, Atlanta, San Francisco, Boston, Moscow, and many, many other cities, even Tashkent. I've sped past lines of crawling traffic going into Chicago, going into Rome, going into Washington, going into London, etc. One of our biggest errors is not allowing "roadway user" taxes to be used for anything other than road construction. In major metro areas, especially in cities laid out prior to the age of automobiles, you just can't accomodate everyone's travel by car, and you couldn't accomodate the cars' needs to park if they did somehow manage to get where they wanted to go.

Ryan in Texas

I have ridden for over 35 years and the only time I had a problem on the street was when a car driver did not watch for others in traffic. wrecked in the dirt a few times when off road but street I only worry about other drivers and maybe some construction ruts.

Its not me who has a problem with motorcycles, but I fear the other drivers.  I have a steel rod in my leg thanks to a driver..not a rider.
