Traffic Jam

They just need to build a under pass at every lights. so they would dig down 20 m by 20 meters & would pre make up big cement slabs. The cement slabs would just drop down & sit in place with pre measurement. So they no what size it is & will dig the road up at the lights. then they will dig down so cars can drive under & the other cars on top. No need for air vents its on like 20m across anyway. Pre made cement lids / slabs. They will be put on top of the road, allowing the cars to go under on 1 side and over / like they do now on the other side. So its easy and cheap. Dig down up to the stopping lines at the light, then pre make cement lids / slabs, That just get dropped onto the road, making a under pass. The under pass would just go under the lights then with in 20 meters on both sides, back up. All lights in the city. NUN of this 30 million under pass. cheap cement slabs that get pre made up & just lower on top, why they have already dug under, & taken the whole top of the road away. So just before it, you will have a small lane that lets people turn off, why the other cars keep going ahead. You could do that easy, because before they reach the road turn off, the other cars would be going 4 meters under that level. That or make 1 way streets as well. you just have to take 1 or 2 extra streets to get there, plus traffic is flowing non stop now / much faster. so just think. dig the road top off and down making a 6 meter ramp then just pre making cement slab that is already to drop onto the top of the road allowing the cars to drive over it on 1 side and under it on the other side. cheap 20 meter tunnel. how much would it cost for a slab of cement 20m by 20 meter stuck on top like a lid.

So often people do not have to be "working" in the same place. Relying more on internet connection work is a tremendous energy reducer. It also saves on transportation costs. With this comes virtual meetings, webinars etc The additional feature is to spread out. As seen in Manhattan, companies in surrounding areas can be reached even faster because of reduced traffic.

This effect is called "TRAFFIC MEMORY".

The story is all too familiar. You’re on your way somewhere, when suddenly you find yourself stuck in traffic. It’s not a typical “rush hour” time of day and normally traffic does not get backed up like this. You figure there must be an accident or some type of serious incident up ahead just out of sight. You slowly creep your way forward, bumper to bumper, continually looking for the flashing lights of ambulances and police cars; the telltale signs of a roadway incident. Then, all of a sudden, traffic begins to move normally again. There is no sign of an accident, incident, or any other cause of the slowdown in traffic. What happened? People all over the world encounter situations very much like this one everyday. Usually, these situations result in a string of various profanities and harsh accusations aimed at fellow drivers’ mothers and driving capabilities. What causes these mysterious traffic jams that continually appear throughout the day for no reason whatsoever? Is it simply the fact that most people just don’t have a clue how to drive? That’s very possible, and in reality there are so many variables involved in something like a traffic jam. But is it possible that the entire traffic jam could be both the continuing and end result of a chain reaction set in motion by a single driver who was in too much of a hurry? Let’s examine one possible scenario: It is a clear, sunny day and the roads contain no obvious hazards that would cause problems with traffic. Traffic on this particular highway is pretty thick, but it is flowing smoothly and steadily. One of the drivers, let’s say a man in a red car, decides that people in his lane are moving much too slowly for his taste. He quickly changes lanes in an attempt to get to a quicker moving lane. He fails to properly check his mirrors and cuts off another driver in the lane beside him. This forces that driver to apply his brakes to avoid getting clipped by the red car. There is no collision, and the man in the red car continues on. The driver who was forced to use their brakes has now slowed a bit, causing the driver behind them to apply their brakes as well. In turn, the person behind them must hit their brakes as well. Human reaction time being what it is, each subsequent time that someone has to hit their brakes, it becomes increasingly more sudden; eventually leading drivers farther down the road having to slam on their brakes and come to a complete stop to avoid rear ending the person in front of them. As a result of this standstill in that lane, drivers begin to change lanes to move to one of the other lanes that are moving properly. As this occurs, the other parallel lanes begin to slow as people are merging over. The same process repeats itself in the other lanes until the entire highway has slowed to a crawl and eventually a complete stop. If the traffic on the highway remains dense and constant, this chain reaction could continue to travel back for miles and could last for an indefinite amount of time. The man in the red car who was in such a rush, probably to hurry home and read the latest article on FailedSuccess.com, may already be home now. He may have sat down on his chair, opened a cold can of beer, and began watching television; while hundreds of drivers are caught in the traffic jam that his actions created. This scenario was once referred to as the “ghost of a traffic jam” by Hannah Holmes, a columnist for Discovery Online, in a lighthearted article on the subject. An occurrence such as this is considered by many to be a plausible theory and a probable cause of many of the traffic jams we experience everyday. The scenario is seated in a theory of Chaos and Non Linear Dynamics. It is similar to the principles of the “domino effect” and the “butterfly effect”. The “butterfly effect” leads to a conclusion that if a butterfly flaps its wings (a seagull was first used as an example for this condition and was changed to a butterfly to make it more poetic), that small disturbance in the chaotic motion of the atmosphere could create a chain reaction; amplifying the effect to that of a large atmospheric motion capable of altering the weather in another part of the world. The “butterfly effect” illustrates the impossibility of making predictions for complex systems. This sensitive dependence on initial conditions is the essence of the Chaos Theory. Our scenario could also be loosely described in terms of a “domino effect”, but the “domino effect” relies on a linear series of identical events. The “butterfly effect”, however, seems to fit our scenario better as it insists that the effect amplifies the condition upon each iteration. In our example of the traffic jam, the effect was amplified each time as drivers were forced into an increasingly stronger, more abrupt action; resulting in a slowdown and eventual standstill. All of this could also lead to additional amplified variables. Car accidents could have been caused by all of this action and reaction, leading to more traffic and events as emergency vehicles are rerouted to the scene of the accident. Some drivers may have taken a different exit than normal to avoid the traffic, leading to increased traffic and incidents on side streets; spreading the condition beyond the confines of the original highway. This would begin impacting traffic and people’s lives all over the city as more actions and reactions result from the original traffic jam. Each reaction led to another reaction creating an end result that was impossible to predict. It’s possible that both theories have some place in describing a situation such as ours. It’s also entirely possible that neither can accurately describe the sequence of events. Many of the events may have occurred without the presence of our “man in the red car”. It’s also possible that if traffic hadn’t been following so closely behind the people forced to brake suddenly, the resulting traffic jam would never have happened. As much as we try to calculate and theorize “chaos”, it is still “chaos”. The long term effects and resulting behavior will become impossible to forecast. So the next time you find yourself stuck in bumper to bumper traffic, it’s very possible that the jackass that caused it is already at home watching the latest episode of American Idol; while you sit in traffic with nothing to do but ponder the finer points of non linear dynamics.
