5/29/2023 0 Comments Michigan gridlockIn traditional models, traffic has been treated as having only two distinct phases - either the cars are moving freely, or they are congested. Introduce a disturbance above a critical level, and like a roll of the dice, this can sometimes - randomly - cause the system to change its phase abruptly and dramatically. Unlike ice resting in a freezer, these systems are all dynamic, and far from equilibrium. In all these cases, the objects can together make abrupt "phase transitions" from one state to another - from a smooth liquid to a molasses-like one, from normal electrical activity to epilepsy, and from free-moving vehicle traffic to a jam. The culprit? Someone in the line of traffic near a light signal slows down, triggering a chain of events that can reduce the speed of all traffic behind it, build up successively longer lines of vehicles with every green-yellow-red cycle, and eventually lead to gridlock.Ĭontinuing a physics approach that originates from the early 1960s, Kerner and his colleagues developed a mathematical description that treats vehicles in traffic like objects in natural systems, such as a network of electrical signals traveling in the brain, or complex molecules in a thick liquid bouncing against each other as they are being sucked up through a straw. Surprisingly, his new model suggests gridlock can occur even when traffic flow is relatively light. A preprint of his new model can be viewed in a preprint at the website arXiv. Striving to figure out how to prevent this urban nuisance, traffic-physics researcher Boris Kerner of the Daimler Automotive Group in Germany has developed an explanation for how gridlock occurs. "On the other hand, I don't want to be the guy sitting in the middle of an intersection when the light changes to red and the cross-traffic is sitting there, aimed at my driver's side door, honking their horns. "It's frustrating when you're at an intersection and you see vehicles in the intersection that shouldn't be," Mitchell said. Greg Mitchell, a manufacturers representative from the Bronx who has driven in New York City for 20 years, has experienced gridlock many times when driving between sales calls in Manhattan. Vehicles that were unable to make it completely through the traffic signal before the light turned red now block the "box" - the area of the intersection where both roads overlap - causing delays and unnerving blares from car horns. (This wikipedia page should be updated as new information is revealed).Gridlock occurs when vehicles cannot pass through an intersection - even if they have a green light and the right of way. Read the rest here -> What is Covid-19 and where did it come from. As of 16 April 2020, more than 2.11 million cases have been reported across 210 countries and territories, resulting in more than 140,000 deaths. While the majority of cases result in mild symptoms, some progress to viral pneumonia and multi-organ failure. The time from exposure to onset of symptoms is typically around five days but may range from two to fourteen days. Other symptoms may include fatigue, muscle pain, diarrhea, sore throat, loss of smell, and abdominal pain. Common symptoms include fever, cough, and shortness of breath. The disease was first identified in December 2019 in Wuhan, the capital of China’s Hubei province, and has since spread globally, resulting in the ongoing 2019–20 coronavirus pandemic.

Whitmer has extended the state’s stay at home order until April 30. Gretchen Whitmer’s “erratic, unilateral orders that threaten Michiganders’ economic existence,” according to a news release. Organized by the Michigan Conservative Coalition and Michigan Freedom Fund, the demonstration, which also included a large gathering of people outside the Capitol building holding signs and waving flags, was in response to Gov. Operation Gridlock-A protest with drivers honking their horns from vehicles surrounding the Michigan State Capitol building took place on Wednesday.
