About DOT

Sustainable Streets Index

Across the five boroughs, DOT supports New York City’s vitality by working to make transportation safer and more efficient for people and commerce alike. This fifth annual Sustainable Streets Index reviews traffic and transit trends in New York City, reports Manhattan traffic speeds based on taxi GPS data, and presents data-driven indicators on the impact of eleven major DOT projects involving changes in street operations. While the Project Indicators are only a sample of DOT’s work to improve New York City’s streets, they reflect how the agency is making our infrastructure greener, safer and more efficient for everyone.

Together with the DOT Sustainable Streets strategic plan, the Sustainable Streets Index allows the agency to implement more performance-driven transportation policy, geared toward achieving the sustainability, mobility, infrastructure and quality of life goals set forth in the City's PlaNYC 2030 initiative.

Project Indicators

This map shows the locations of 11 major DOT projects that were chosen as examples of the types of projects DOT regularly undertakes in neighborhoods around the City to improve safety and mobility. DOT collected before and after data for each project to assess its impacts on impacts on safety, usage for motor vehicles, cyclists, pedestrians and bus riders and/or travel times through the project area.
