The roads may soon teem with miles of new bike lanes, made possible by Michael R. Bloomberg. In Turkey.

High-capacity buses zip through exclusive traffic corridors, part of Mr. Bloomberg’s bet that better public transit options will discourage private car use. In Brazil and Mexico.

And in Egypt, between the uprisings in the streets, speed-tracking cameras were hung along the Ring Road of Cairo. They resemble the ones expected to reach New York City, eventually, under a bill approved in Albany last month.

Though often hamstrung at home by headstrong state lawmakers, an entrenched taxi industry and a city in which even a single bike lane can inspire years of litigation, Mr. Bloomberg has found success overseas in pushing — and financing — a global transportation agenda during his final years as the mayor of New York City.
