Tunnels feature class (Tunnels)

The Tunnels feature class is a subset of Streets where Tunnel = Y. The Tunnel layer supports cartographic use cases.

For a description of the attributes OBJECTID, Shape, GlobalID, and Shape_Length, see Esri® system fields.

Field name	Data type	Description
STREET_NAME	String (100)	Cartographic label for each street segment, the full street name of the segment including the abbreviated street type, prefix and suffix, for example "Fred St S". Where multiple names exist for a street segment, the data includes the one most likely to be useful for cartographic display of highways as identified where possible
LANGUAGE_CODE	String (3)	The language associated with the feature name
STREET_NAME_LATIN	String (100)	`STREET_NAME` is a cartographic label for each street segment, using Latin character set, the full street name of the segment including the abbreviated street type, prefix, and suffix, for example "Fred St S". Where multiple names exist for a street segment, the data includes the one most likely to be useful for cartographic display of highways as identified where possible
LANGUAGE_CODE_LATIN	String (3)	The language associated with the feature name, using Latin character set
FUNCTIONAL_CLASS	Integer (4)	The functional class of street segments defines the segment's role within the hierarchical street network and determine logical and efficient routes in routing applications. `FUNCTIONAL_CLASS = 1` roads allow for high volume, maximum speed traffic movement between and through major metropolitan areas. `FUNCTIONAL_CLASS 1` applies to roads with very few, if any, speed changes. `FUNCTIONAL_CLASS 2` roads channel traffic to roads with `FUNCTIONAL_CLASS 1` for travel between and through cities in the shortest amount of time. `FUNCTIONAL_CLASS 2` roads have very few, if any speed changes that allow for high volume, high speed traffic movement. `FUNCTIONAL_CLASS 3` roads interconnect `FUNCTIONAL_CLASS 2` roads and provide a high volume of traffic movement at a lower level of mobility than `FUNCTIONAL_CLASS 2` roads. `FUNCTIONAL_CLASS 4` roads provide for a high volume of traffic movement at moderate speeds between neighbourhoods. These roads connect with higher functional class roads to collect and distribute traffic between neighbourhoods. `FUNCTIONAL_CLASS 5` roads' volume and traffic movement are below the level of any other functional class. In addition, walkways, truck only roads, bus only roads, and emergency vehicle only roads receive `FUNCTIONAL_CLASS 5` roads.
