NYC Digital City Map Arterials and Major Streets

Description

A spatial dataset containing arterial and major street routes from the New York City Digital City Map (DCM). This layer represents the primary road network designated as arterials and major streets for traffic planning and management.

Usage

nyc_dcm_arterial_sf

Format

An sf object with 740 features and 7 fields:

borough

Character. The borough name (Manhattan, Brooklyn, Queens, Bronx, or Staten Island)

boro_code

Integer. Numeric borough code (1=Manhattan, 2=Bronx, 3=Brooklyn, 4=Queens, 5=Staten Island)

route_name

Character. The name of the arterial or major street route

route_type

Character. Classification of the route type (e.g., "Major Streets")

route_sub

Character. Sub-classification of the route (e.g., "Major Street", "Major street to be improved")

route_stat

Character. Current status of the route (e.g., "Existing")

geometry

sfc_MULTILINESTRING. Spatial geometry representing the arterial or major street

Details

The coordinate reference system is NAD83 / New York Long Island (ftUS), EPSG:2263. This projection uses US survey feet as units.

Arterials and major streets form the backbone of NYC's street network and are important for traffic planning, emergency services routing, and understanding the city's primary transportation corridors.
