Why does traffic congestion occur ? What is the effect of number of freeway lanes on congestion ?
349218
Traffic congestion usually occurs because the capacity of intersections is lower than the capacity of roads. That's why you get queues of traffic at junctions. \n\nThe effect of the number of lanes on the capacity of a road is roughly linear -- double the number of lanes and, at a high cost, you double the capacity of the road. The effect on a road system with lots of junctions will be small, though, and only noticeable under low load conditions.\n\nIn general, money spent making the intersections less disruptive of traffic flow is better than money spent on adding lanes.

Theoretically, there isn't any significant difference in many cases in actual usage.  Way back when however, a road was often not paved, a street was a paved road, a boulevard was a large street, a lane was a connector between a road and a street, and a court would be a dead end type road or street.

Nothing it means the same thing....different cultures and countries have different names....basically "freeway" means no tolls....here is the defination which can be found at:\n\n:) Peace...\n\n Nomenclature\nThe terms used for various types of highways such as freeway, expressway, motorway and autobahn, vary between countries or even regions within a country. In some places a highway is a specific type of major road that is distinct from freeway or expressway; in other places the terms may overlap. In law highway may mean any public road or canal. However, in some countries, the term highway is not generally used at all.

Well, if you're driving, looking where you're going, making sure to drive at the correct speed, looking for an address, worrying about missing that address, AND listening to the radio, you're doing a LOT of things at the same time. Even the best multi-taskers have their limit and need to cut out one of those activities in order to perform the others successfully.

Sherman Oaks or Studio City.  Both really nice areas with lots to do.  Shops, restaurants, bars, etc.  Just a very nice place to be and it's also easy to get to Burbank.  No freeways are needed.  I used to do that commute myself.

There could be road construction. Usually it's people changing lanes, trying to get from the far left lane to the exit ramp on the far right, people trying to get on the expressway, people talking on their cellphones and driving slower, old people driving slow...

At worst, it puts a dead stop to any further downslide.\nThink of it like an out-of-control truck being stopped by a massive roadblock.  There will still be an accident, but less damage than if you allowed that out-of-control truck to continue careening down the highway.

Back when I was using my 98  stupid me I tried\nTraffic Swarm  and it jammed my email.  I had to use web mail and delete things one by one that was extremely time consuming!  It was less than a month that I tried Traffic Swarm\nis that what you ment?  I never heard of Traffic Swam but  heard of  Traffic Swami and  Traffic Swarm.  Traffic Swarm is probably okay for those that have high speed internet but not good for those on dial up!

Well, this is a very technical question, and difficult to tell it in a small space, bt I will try to be simple and short.\nThe Net is a collection of computers bound togather by phone networks. Hence, just as we experience congestion on phone lines, when many people dial up simultaneously, similarly, when many people go for surfing simultaneously, it creates a load on net connection, and we feel that Net behaves as if its gone crazy.

Essentially we have various forms of data and we want to transmit them to the appropriate places. The superhighway, to use the analogy, is similar to a highway with cars - we have different cars traveling at different speeds, with different people driving them, with different destinations. If we imagine multiple data streams being the cars, and the data being the drivers/passengers and the destination being the end user then the analogy becomes clear. The superhighway is a method of transmitting various forms of data at different speeds to the end user. The highway can have different lanes for different speeds, the fastest data traveling on the outside lane and the slowest on the inside. The good things is we can multiplex the slow data into the high speed lane using an analogy of a truck that travels at 100Mb/s and put the data/car, travelling at 1Mb/s, on the back of the truck. Voila.

Traffic always works!  And never ever volunteer information.  I make it a habbit to stay over somtimes.  Or I will come early and leave early. LOL

You have a bad or congested network connection.

Ha.\n\nThe Straight Dope has an excellent explanation, as does Wikipedia's definition of Parkway.\n\nFrom Wikipedia: Historically, the term "parkway" has often implied that the road was designed specifically with a naturalistic or manicured landscaping of the median and adjacent land areas meant to suggest a pastoral driving experience, isolated from the manifestations of commerce and advertising, even when the road passes through populated areas; for this reason commercial traffic is excluded. Many parkways have signature road signs with special emblems that suggest a thematic driving experience and increase the sense of isolation from civilization in the vicinity of the road.

the area is new to you and so you need more concentration on the area map. radio volume, at an acute level, may cause a barrier to your concentration process. Even, i drive slow.

Yes, I have given out many traffic tickets in a variety of bad weather scenarios over my career. Likewise, I have stopped and warned many drivers for their actions in bad weather also.
