With Metro seemingly on the verge of collapse and D.C.’s streets still pocked with winter’s potholes, District residents are in agreement that our fair city’s transportation infrastructure needs to improve. Normally, people would take their complaints to neighborhood listservs or Twitter, but on Monday night, Politics & Prose offers them an opportunity to grouse in the company of an expert. Janette Sadik-Khan, New York’s former transportation commissioner, appears at the store to discuss her new book, Streetfight: Handbook for an Urban Revolution. Sadik-Khan isn’t looking to start a physical conflict; instead, she looks back on her work transforming the ways streets work and bringing more people to them. Her methods are not particularly controversial—chief among them are designating bike lanes and repainting crosswalks—but by making urban areas more friendly to non-drivers, Sadik-Khan has made streets safer and more welcoming to businesses. As entrepreneurs and homeowners continue to develop D.C., taking a tip or two from this expert can only help. Janette Sadik-Khan reads at 7 p.m. at Politics & Prose, 5015 Connecticut Ave. NW. Free.
