Sustainable Streets Index
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 Mayor Bloomberg’s PlaNYC 2030 initiative.
The Sustainable Streets Index provides data on recent trends in traffic, parking, travel and safety. It also includes a section on "project indicators", an assessment of 11 major DOT projects completed by the end of 2009. This assessment covers the impacts on safety, usage for motor vehicles, cyclists, pedestrians, bus riders and travel times in the project areas. These projects are also mapped below.

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.
- Gerritsen Avenue
Injuries from vehicular crashes decreased by 48% along Gerritsen Avenue after narrowing the roadway and installing a painted median, left-turn bays, a pedestrian refuge island and other improvements.
- West Houston Street
Injuries from vehicular crashes decreased by 24% along Houston Street after implementation of lane reconfigurations, dedicated left-turn bays, new medians, pedestrian refuge islands and other improvements.
- Allen and Pike Streets
Injuries to motor vehicle occupants and bicyclists both decreased by 35% on Allen and Pike Streets after DOT implemented a lane reconfiguration,dedicated left-turn bays, pedestrian plazas, pedestrian refuge islands and other improvements.
- Jackson Avenue/Pulaski Bridge
Pedestrian safety and connectivity improved in the area of Jackson Avenue and the Pulaski Bridge with the installation of pedestrian refuge islands, signal-protected crosswalks and upgraded crosswalk marking. Traffic delays fell by 70% for northbound vehicles coming off the Pulaski Bridge making a right onto Jackson Avenue after lane reconfigurations and signal timing changes.
- Park Circle
New pedestrian refuge islands, crosswalks, traffic signals, pavement markings, signage, bike and bridle paths, and landscaping have made the traffic circle more attractive and accessible to pedestrians, bike riders and horse riders, while also decreasing travel times.
- Allerton Avenue
A new bike lane, pedestrian refuge islands and a narrower roadway have created a safer environment for pedestrians while calming traffic, leading to a decrease in speeding.
- 34th Street Bus Priority
At a time when other crosstown buses were losing passengers by about 5%, bus ridership along 34th Street in Manhattan increased by up to 6% after installation of bus countdown clocks and other improvements. .
- Belt Parkway Access/Egress Improvements
DOT increased capacity and reduced delay for motorists along Bay Parkway between Cropsey Avenue and the Belt Parkway. The number of crashes involving injuries to pedestrians and motor vehicle occupants after implementation was lower than the average for the three prior years.
- Amboy Road
Travel times improved by up to two minutes on Amboy Road after DOT retimed traffic signals, reconfigured lanes, installed left-turn bays and made other improvements.
- Off-Hour Deliveries
Delivery trucks saw travel times improve 130% from a pilot of off-hour deliveries, based on a comparison of evening and midday travel speeds.
- PARK Smart - Park Slope Pilot
Parking duration fell by 20% in Park Slope due to the pilot, enabling more drivers to find metered spaces and reducing overall traffic volumes on the neighborhood’s main commercial avenues.
