Legendary Transportation Engineer Alan Voorhees Passes Away

"Early in his career, Voorhees, an engineer who specialized in transportation projects, devised a mathematical model to predict traffic patterns. This formula has helped planners build highways, subway systems, shopping centers, apartment buildings and office complexes throughout the world.

...In the late 1950s, before a single mile of the interstate highway system had been built, Voorhees was one of its early planners, particularly in determining how the highways should go through and around cities. Later, he helped plan subway systems around the world, including Washington's Metro."
