First off, well done, this is excellently written! I'll just go through and point out any small errors I see. 

How to beat traffic jams

Everyone has experienced traffic jams. They seem to be an incurable disease of modern cities. With billions of dollars invested in the road infrastructure, commute times continue to rise. Many people become frustrated by spending several hours a day in a slowly moving traffic jam. That situation is an inevitable result of the recent urban sprawl.

Various measures have been proposed to solve the transportation problems, but the majority of them had [here you switched from present perfect to past perfect, I would stay with present perfect, so 'have had', instead of just 'had'] little success. The most effective solutions is [are, solutions is plural] the most radical ones. To reduce traffic, we should either restrict the usage of land, or limit the usage of cars.

The whole situation, in which a city dweller has to drive a car on everyday basis, is regarded as abnormal by a few famous urbanists (Vukan Vuchic to be mentioned). They argue that a megalopolis should rely primary on a public transportation system, which can include buses, trams, LRT trains, and a subway. Nevertheless, proponents of “car-free cities” have failed to prove [the] efficiency of their concepts: while LRT (light rail transit) systems in European cities turned out to be a big improvement, we cannot say the same about but lines [I don't understand, the same about but lines?] . Thus, the cars are not going to disappear.

The most prominent solution for an excess usage of cars is reducing the actual need for transportation. That includes relocating offices from the city center to more distant areas, and using the Internet for new forms of employment, which do not require physical collocation of workers. If all stereotypes [this is an unusual use of the word stereotype. It might be appropriate, but clarify what you mean by stereotype then] were disposed, and everyone were able to work in the most convenient way, cities as we know them would disappear. We would live in small cities again. There would be no need for motor vehicles then...

Again, your writing is very good! Also, I'm very sorry about your traffic situation, I thought it was bad in the Bay Area!
