Traffic Signals, Stop Signs and Crossings (OpenStreetMap)

Where traffic is controlled on Massachusetts's streets, as mapped by OpenStreetMap's volunteers: traffic signals, stop signs (and which are all-way stops), yield signs, pedestrian crosswalks with their markings and signals, railroad grade crossings, and speed humps, raised crosswalks, chicanes and other traffic calming. No statewide public inventory carries these. Good for pedestrian and safety studies, signal and stop-control counts along a corridor, crossing spacing, and finding where traffic calming already exists; coverage depends on how thoroughly volunteers have mapped each town.

From the publisher

OpenStreetMap is built by a community of mappers that contribute and maintain data about roads, trails, cafés, railway stations, and much more, all over the world.

OpenStreetMap emphasizes local knowledge. Contributors use aerial imagery, GPS devices, and low-tech field maps to verify that OSM is accurate and up to date.

OpenStreetMap is open data, licensed under the Open Data Commons Open Database License (ODbL) by the OpenStreetMap Foundation (OSMF). You are free to copy, distribute, transmit and adapt our data, as long as you credit OpenStreetMap and its contributors. If you alter or build upon our data, you may distribute the result only under the same license.

How this table is made

© OpenStreetMap contributors. Read from Geofabrik's extract of OpenStreetMap for Massachusetts with GDAL's OpenStreetMap driver, keeping only the tags in the table below. A point (an OpenStreetMap node) is kept when it carries highway=traffic_signals, highway=stop, highway=give_way or highway=crossing, railway=level_crossing, or any traffic_calming value. Signals, signs and calming mapped on a road's line rather than as a point are not included. No other tags are loaded, and Geofabrik's extracts carry no mapper names. Each row is one OpenStreetMap node, identified by its type and id, so it can be looked up on openstreetmap.org.
