Plenty of opportunities on the calendar this week to brainstorm the future of urban design. There’s also a chance to weigh in on present-day improvements to Broadway — and to choose the city’s next comptroller and public advocate.

• Tuesday: Primary day runoffs. Remember to vote! Polls are open from 6 a.m. – 9 p.m.
• Tuesday: At this month’s Auto-Free New York meeting, John Rozankowski speaks
  about the idea of putting the subway and bus systems under city
  control. 6 p.m.
• Thursday: The DOT is gauging public reaction to car-free spaces on
  Broadway from 59th St. to 23rd St. Got an opinion about the new
  Times Square, Herald Square or Madison Square? Be part of the conversation at today’s public feedback session. 10 a.m.
• Thursday: Details are still murky, but the two-day IBM Smarter Cities Conference gets underway
  today. Among the speakers are Robert D. Yaro of the Regional Plan Association, Kathryn
  Wylde of the Partnership for New York City, and Petra Todorovich of
  America 2050.
• Thursday: The Municipal Art Society exhibit "Re-Imagining Cities: Urban Design
  After the Age of Oil" opens with a reception from 6:30 – 8 p.m. This
  had been a members-only reception, but limited
  spots for the general public are now available. The exhibit will be on display through
  December 4.
• Sunday: The Atlantic Antic hosts the 16th Annual New York Transit Museum Bus Festival. 10 a.m. – 4 p.m.
