This is an excellent 7-minute film that travels to Bogotá, Colombia to show you how the city runs a bus-centered transit system that is modern, inexpensive and efficiently moves 1.3 million people a day, integrating bicycles and auto free zones--and all without relying on rail or subways.  The backbone of the system is a network of Bus Rapid Transit (BRT) lines that run on Bus Only Lanes.  Click here to watch the film.

The film also notes that Bogota built their BRT system by choosing it as an alternative to building a proposed new network of elevated highways!

This kind of BRT system would work in L.A.  Bus Rapid Transit caught big attention this summer when the New York Times featured Bogotá's BRT system in a front-page story, "Buses May Aid Climate Battle in Poor Cities":

Bogotá, Colombia, has implemented a bus rapid transit system, which
improves traffic flow and reduces smog at a fraction of the cost of
building a subway.

Versions of these systems are being planned or built in dozens of
developing cities around the world — Mexico City, Cape Town, Jakarta,
Indonesia, and Ahmedabad, India, to name a few — providing public
transportation that improves traffic flow and reduces smog at a
fraction of the cost of building a subway.

The film comes Aaron Naparstek of Streetsblog and the Livable Streets Initiative.
