May, of course, is bike month, and this week’s calendar is packed with cycling activities, including city cycling lessons, bike-share events and a Saturday tour of bike-friendly businesses.

The week kicks off with an important meeting on the future of Brooklyn’s Fourth Avenue, one of the deadliest streets in the five boroughs. Lined with several schools, Fourth Avenue in Sunset Park is a major walking destination for children and families. It’s also a high-speed traffic disaster: From 2008 to 2010 alone, three pedestrians lost their lives in crashes on the stretch that DOT and Community Board 7 will discuss tonight. The public is invited to attend, and support for traffic calming measures could save lives.

• Today: At a meeting of the Brooklyn Community Board 7 Fourth Avenue working group, DOT will present preliminary plans for safety improvements to Fourth from 15th to 65th Streets in Sunset Park. The plans are based on community visioning sessions held in February and March. As with any community board committee, public input is crucial. The DOT flier is here. CB 7 board room, 4201 Fourth Ave.; entrance on 43rd St. 7 p.m.
• Today: The Manhattan CB 5 transportation committee will be holding two back-to-back meetings. The first will feature a presentation by NYU’s Wagner School: “A Capstone Project: A Study of the Penn Station Area.” The second meeting will feature a presentation from the city’s Department of Design and Construction on the revised design for Broadway between W. 42nd and W. 47th Streets. 6 p.m.
• Tuesday: The Rudin Center for Transportation Policy & Management presents “Technology and Urban Mobility: Perspectives from the Front Lines,” a look into technology’s influence on mobility management in New York City. Featuring representatives from the MTA, the Port Authority and Jeff Maki of OpenPlans. 8:30 a.m. RSVP online.
• Tuesday: Would you like to bicycle (or bike more), but don’t feel comfortable riding in city traffic? Volunteers from the Five Borough Bicycle Club will explain your rights to the road, the skills needed to assert them, and how to safely fit in with motor vehicles and ride without stressing out. Hosted by the Park Slope Food Co-Op. 6:30 p.m.
• Wednesday: DOT is holding information sessions on its NYC Plaza Program in each borough. Wednesday’s session will be on Staten Island. 10 a.m.

Entrance fee required.
