Toartat’s 45 $ 13 trillion dollar makesover in Houston. The project aims Reduce congestion Adding new lanes – I-35, I-35 million I-35 billion projects are being expanded as part of the I-35 Billion project, and near California. A planned project that represents the important expansion of the new New Jersey Turnpike will cost $ 10.7 million.
Despite massive price tags, these projects are likely to reduce accumulation for a long time. This is due to a phenomenon required by transport researchers, due to demand, in areas with many demands of driving, the new capacity of add-ons is also complied with.
After the project, “We are back a little better … And when we were back to the place. And someone said,” Oh, Susan Handy, Davis. “Then how far Will he go? “

Already quite distant 12 road highways hit a lot Main cities Throughout the US, but there are fewer types of traffic liberation valves: Accumulation prices. It can be a win-win for cities and drivers, and can free money to invest in the future, invest in the place where everyone can spend less time in traffic.
Extending paths has been at least a century of accumulation reduction strategy, Handy says. It seems logical and intuitive: If you have limited supply of something in high demand, such as the ability to drive a certain road stretch, increasing supply, adding new paths that should be made available to more people.
Increasing the supply of something, it also falls the cost, which can take advantage of more people. More supply is sometimes induced in demand, or at least allows you to express more requirements. “Adding capacity driving is cheaper for travel time and inconvenience and annoyance,” Handy says. More people can have the opportunity to drive on the road that can take part, and eventually cause congestion of rebellion.
Whether the congestion returns returned in previous levels, it is already dependent on the Pent-up request, which is as far as people choose to drive during the circulation during that road. In very congested sites, “everyone has some versions to adapt to traffic congestion,” says Kelcie Ralph, transportation planning researchers at the University of Rutgers.
For Ralph, they are damaged habits. It is more than driving a gym with a pool, but walks across campus, usually walking closest to his office to avoid cutting-edge traffic. Meanwhile, someone else can choose to go to the grocery store next to the food instead of driving to full food in the next town. Another can choose to stay at home than driving around a nearby city.
The stage and up cituque spectra may prevent people from doing completely, Mark Burris, Civil Engineer Texas A & M University. But usually people adjust the travel time, route or transport mode to prevent traffic. People to work can reach the crack of the crack of the dawn, to win the cutting-edge time, use a train to walk or take more roundabouts to the office. In the same way, when a highway spreads, and when the accumulation is reduced, the suburbs can drive at the top time and so they causing backwards.
But even if the accumulation returns, a wide highway can take more cars. Additional barriers increase the traffic volume that passes from the accumulated area per hour, which means that it takes a career that they prefer more drivers, as Burris says. “With time, the accumulation is usually returned, but it is a bunch of benefits for people who are traveling there,” he said. “They have really achieved differences in lifestyle that they benefit, and you can’t ignore these benefits.”
The question becomes then: Do these benefits deserve costs? The cost can be money, such as the price of expansion price and the money needed to carry out constant maintenance. Then there is a cost of human health and the environment. Earning on the highway capacity involves a greater number of idling cars, which increases pollution of carbon dioxide, particles and noises. This affects disproportionate Colored peopleWhose communities are frequently visited by city highways due to discriminatory housing and development policy. Exposure of these pollutants can increase rates Lung disease, especially childhood asthma, heart disease and Learning delays.
For urban planners such as Ralph and Handy, it is a way to double our cities and towns in a sustainable way (most people should not be stuck in traffic), different needs to adapt to many modes of transport. The most important projects for expanding “” block us in decades of infrastructure that does not build the future we want or does not build the future I You want, “Ralph says. Often, the money would be better to invest in reliable relatives and expanders of the train, better massive passes or safe walking paths.
Fortunately, for people who are currently stuck in traffic, the congestion price programs are short-term solutions that operate as the congestion “valves” and are being implemented across the country. Unlike the expansion, it decreases the cost of driving, so it affects the demand for bouncers, regulating the cost of driving in a given area or in a lane to decline in traffic, according to Burris. Some such programs have just taken out in New York City, including tolls to access the high volume site. They also have similar programs in London, Stockholm and Oslo.
Another popular point of congestion is to use high-occupancy toll (heat), the faster paths that can pay for drivers. Highways of large cities, Houston, Seattle, Los Angeles, Salt City, Utah and Charlotte, NC, are fixed prices that change hot paths during the day; Others have dynamic price models that are updated in minutes to continue moving traffic. In any case, whether drivers can use them or not, and those who do not pay can take advantage of those who do not pay; The presence of at least one lined traffic lane often makes things for all.
The congestion price programs cost much less than projects to expand highway projects, and generate income that can be invested in other types of transport, including mass transport. Because drivers live directly to price costs directly, sometimes it can be hard for sale. But starting to observe people’s accumulation price programs, “You almost always see the acceptance rating upwards,” Burris says.
“When people see it, he likes time and time again,” Ralph explained.
While spreading the highway is not always a bad option, Ralph stressed the importance of what the opportunity it offers with this view. Extending projects is sold to the public because of throwing advantages that will not last, but the unnoticed costs will remain in decades. “According to what we really know,” I want to make you aware of what we think is what we mean.
