Bus Rapid Transit Systems

I love the idea of  Bus Rapid Transit systems, because it is the best place to START for public transportation in practically all cities. I think that to jump right into a Metro system, is not going to be practical for everyone and way to costly for everyone's budget. 

 No matter how many roads you build, you will never satisfy city traffic, in fact I would postulate that city traffic would just grow, and just be a mess of fly-overs. NO city should have to look like Los Angeles, that would be a tragedy.  

What the BRT system allows for is a traffic-less bus networking system that is very easy to implement throughout the entire city. Lanes on streets would be strictly dedicated to the buses, and roads would be maintained by the private transit company. So, all around the city we'd see... well a lot of buses. Buses and Bus Lanes, sounds boring, I know. But what would be different about these buses compared to the buses of today, is that the would be MUCH faster, bc traffic is eliminated, and it would be more convenient because the network would cater to the entire city. 

I would imagine that the bus would eventually get more and more crowded, and bus would get longer, like a TRAIN... maybe double decker... maybe the buses will take on a metro like face to optimize speed... genius idea...
