Today begins many drivers' nightmares: The United Nations General Assembly. High-profile world leaders—and their big entourages—are descending upon the city, and the NYPD is bracing, closing numerous streets (see the full list below) and warning the general public that "The use of public transportation for the duration of the General Assembly is highly encouraged."

The United Nations is located at First Avenue and 42nd Street, which means if you have to go there by motor vehicle today or tomorrow (when the ministerial session begins), you'll probably regret it—read the list of closures below. And it's not going to be a fun time inside the UNGA either—a Council on Foreign Relations fellow, Stewart Patrick, tells the Daily News, "The Security Council is basically paralyzed," because of the issues with the Syrian conflict and Iran's nuclear program. The News reports, "The Security Council remains deadlocked over how to address the conflict, with China and Russia supporting Assad and refusing to green-light stiff sanctions against Iran." Patrick added, "This is going to be a downbeat session. It's a much more intense international environment than last year."

United Nations Secretary General Ban Ki-Moon said it will be a busy session reflecting "the tumultuous time in which we live - a time of turmoil and transition... against a backdrop of widespread violence linked to intolerance." According to the AP, he also invited all leaders to a meeting of the rule of law "to send a strong signal to the world's people that they are serious about establishing well-functioning institutions and delivering justice."

President Obama will be arriving in New York today for the UNGA—Syria and Iran are among his potential "potholes" according to Time—the others are the Middle East uprisings, China vs. Japan and climate change.
