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.
