Vivek and his colleagues performed computer simulations of traffic flow in Manhattan, using a statistical method called percolation theory. And unlike compromised data, compromised vehicles can lead to physical injury. Worst-case scenario: a small-scale hack affecting just ten percent of cars on the road would be sufficient to cause city-wide gridlock, essentially cutting half of Manhattan off from the rest of the city. Skanda Vivek, a postdoctoral researcher at Georgia Tech, described the study's findings at the American Physical Society's 2019 March meeting, held last week in Boston. That question inspired scientists at the Georgia Institute of Technology to quantify the likely impact of such a large-scale hack on traffic flow in New York City. That poses a unique potential risk: if someone can hack one car, what happens if they manage to hack many at once in a major metropolitan city? Vehicles on the road will only have greater interconnectivity from this point forward, with self-driving cars on the horizon. Department of Transportation’s University Transportation Centers Program.In 2015, a pair of hackers demonstrated just how easy it was to break into the UConnect system of a Jeep Cherokee, remotely manipulating the speed, braking, steering, even shutting the car down entirely. But if we want to avoid climate change impact, these are the kind of policies that need to be considered and implemented.”įunding for this research was provided by the U.S. “All of us know that policymakers don’t like to charge people for driving into the city. They are facts of what will happen,” Tayarani said. “If we want to make cities livable for the next generation, installing these tolls are a practical solution, because these plans are not imaginary.
For a $10 toll, the reduction would be 119,097 tons, and a $15 toll would yield a 157,747-ton drop.Ī $20 toll would eliminate 40% of midtown traffic and reduce greenhouse gas emissions by 182,065 tons per year.Įntrance tolls will also drop the volume of particulate – soot and other tiny particles measuring less than 2.5 micrometers that are linked to poor health and give Manhattan a hanging haze, according to the paper. In modeling different scenarios using air quality processing software, the researchers determined exhaust emission reductions based on the tolls charged to enter the central business district of Manhattan.Ī toll of $5, they found, would result in a reduction of 72,648 tons of greenhouse gas emissions annually. 1, 2021, but delays due to the COVID-19 pandemic and delays in federal approval means collections will likely be pushed back, according to the governor and Metropolitan Transportation Authority.Ībout 1 million tons of greenhouse gas emissions – mostly carbon dioxide – come from automobile and truck traffic in lower Manhattan annually. Andrew Cuomo urged the Legislature to pass congestion traffic pricing to cull vehicles from the central business district of Manhattan, and to help fund more than $1 billion in public transit and subway infrastructure repairs. In the same 2019 New York state budget bill that spelled the end of plastic retail bags, Gov. Traffic woes have plagued Manhattan for decades. In addition to Gao, authors are Cornell postdoctoral researcher Mohammad Tayarani, CCNY postdoc Amirhossein Baghestani and Mahdieh Allahviranloo, CCNY assistant professor of engineering. The research, “ Evaluating the Traffic and Emissions Impacts of New York City Cordon Pricing,” was published May 1 in the journal Sustainability. “This is good news for the environment and from a public health perspective.” “If we charge a high dollar amount of tolls, we can decrease the number of cars and taxis, shrink gridlock, bring down carbon dioxide emissions and reduce particulate matter,” said Oliver Gao, professor of engineering and director of Cornell’s Center for Transportation, Environment and Community Health.
