　　Transportation Infrastructure

　　__①__ As has been demonstrated repeatedly, a transportation infrastructure based around individuals in automobiles contributes to global warming, pollution, health problems and energy insecurity. Conversely,the idea behind a green transportation infrastructure is one that provides opportunities for people to get around their communities using their own power--such as walking or biking--or by other more environmentally sensitive means, like trains or buses. Sometimes, the best definition of a concept can be found by describing what it is not.

　　All one has to do to get across the idea is to highlight the experience virtually all of us have shared at some point in our life(and for millions of Americans it can be literally an everyday experience) : sitting in our motionless cars on a jam-packed highway as the vehicles spew emissions and pollution into the air. Even in cases when it’s difficult or impossible to remove the car from the picture entirely, there are ways to green our transportation infrastructure and improve our health and quality of life. Therefore, we have to find out some ways to improve what’s already in place.

　　__②__ A lot of city dwellers hold that they prefer to drive cars to work.Sure, there are plenty of reasons keeping them in the cars. Convenience is obviously one, but having to wait at a bus stop and then sit or stand on a crowded bus while cars go by is definitely another big trouble. But cities around the world are doing their best to employ the environmental benefits of bus ridership by making them more attractire to ride.0ne major way is by creating laries dedicated to buses so that they can zoom past cars and trucks on roadways.

　　__③__ Fun is j ust one of the many benefits to cities and towns that commit to making biking easy and safe.“Cleaner，healthier，quieter and safer neighborhoods”，are the results of making bikeways and 1anes a priority，says Zehner，who argues that even though American cities are more spread out than those in Europe，they are still great candidates for bikes.If Americans can embrace the concept it will make us more like the rest of the world;indeed。Zehner says the bike is the predominant mode of transport globally，with around 2 billion people using them.

　　__④__ When it was originally built in l889，the Poughkeepsie-Highland Railroad Bridge in Poughkeepsie，N.Y.，was all about commerce and transportation，allowing people and goods to flow easily over the Hudson River.For years，the bridge sat unused after a fire nearly destroyed it in 1974 untiI a group called Walkway over the Hudson hegan its efforts to transform the bridge into a place for the public to enjoy.The group was finally successful in its efforts when the Walk way over the Hudson State Park opened in 2009--making it the iongest pedestrian bridge in the world，which has since attracted more than l million visitors.Pedestrian bridges provide opportunities for alternative，environmentally friendly transportation modes such as biking and walking.

　　__⑤__ Giving people the opportunity and encouragement to get out and walk sometimes takes a little creativity，especially in hyper-urban areas like New York City.In the city’s old Meatpacking District，a group of committed citizens have transformed what was once a piece of what would now be called green irfrastructure--an elevated railway line and transformed it into a nearly 1.5-mile walkway and park on the west side of Manhattan called the High Line.What was a transportation route for meat and other agricultural goods heading into factories and warehouses from 1934 to 1980 is now a popular park with areas for public art and urban gardens.
