From http://www.nyc.gov/html/dot/html/about/vz_datafeeds.shtml harvest the following items into some CARTO tables:

• Enhanced Crossings - point, buffer to 90-foot circle
• Leading Pedestrian Interval - point, buffer to 90-foot circle
• Left Turn Traffic Calming - point, buffer to 90-foot circle
• Neighborhood Slow Zones - polygon
• Speed Humps - line
• Street Improvement Projects (Intersections) - point, buffer to 90-foot circle
• Street Improvement Projects (Corridors) - line
• 25mph Signal Timing - line

On the Map, create a new “Interventions” section.

• Has these 8 layers, and checkboxes and legend swatches. Toggling them toggles that layer.
