It’s a light week on the Streetsblog calendar, but mid-summer is a great time to start fighting for better transit and safer streets. Plus, NYC’s biggest car-free event — Summer Streets — comes back to Lafayette Street and Park Avenue for six hours this Saturday.

• Tuesday: Join the Riders Alliance for a strategy session about how to improve transit in Astoria and Long Island City. 6:00 p.m.
• Thursday: Get involved with neighborhood campaigns for livable streets at the monthly meeting of Transportation Alternatives’ Manhattan Activist Committee. 6:30 p.m.
• Saturday: It’s the first installment of the sixth year of Summer Streets. This year’s highlight — car-free access to the Park Avenue tunnel. 7:00 a.m. to 1:00 p.m.
• Saturday and Sunday: Neighborhood car-free events come to 46th Street in Sunnyside and East 204th Street in Norwood.
