Roadway asset types

This table describes special features of each of the roadway asset types.

Note: The asset types that are available to you depend on your access rights and on the asset products that your agency has purchased.


Asset type	Special features
Appurtenance	An appurtenance is a miscellaneous roadway asset that does not fall under any of the other asset types, such as a bus shelter, bench, or historical marker. Use the Associated Assets grid to associate other assets with the appurtenance, such as a sidewalk or landscape where it is located. Several fields indicate structural information about the appurtenance, such as its color and dimensions.
Bridge	Several elements indicate structural information about the bridge, such as its weight limit, foundation type, and construction materials. The fields under Geometric indicate the bridge's dimensions, such as its maximum span length, deck width, and underclearance measurements. The elements under Class/Nav indicate classification information about the bridge, such as its functional classification and its historical significance. The Navigation fields indicate structural information for a bridge that spans a waterway, such as its type of navigation control on navigable streams or its vertical and horizontal clearances. Use the Components tab to define components of the bridge that can be inspected separately.
Culvert	A culvert is a pipe or box structure that passes under a roadway, controlling the flow of stormwater across the roadway. Several fields indicate structural information about the culvert, such as its number of barrels, its debris control method, and information about its inlet and outlet. Some culverts have multiple inlets, or barrels.
Intersection	Use the Associated Assets grid to associate other assets with the intersection, such as a street light or sign located at the intersection.
Landscape	A landscape is any portion of land along a roadway, such as a planted median or bank. Several fields indicate structural information about the landscape, such as its type and dimensions.
Light	The Position field shows the light's position at the address. The position cannot exceed the maximum number of positions allowed for street lights at the address, and a position of 0 indicates that the light is not in use. Several fields indicate technical information about the light, its control, and its pole. Use the Name Plate grid to record data from the light's name plate, such as its model and manufacturer. Use the Performance Indicators grid to record a performance reading for the light, such as its average lamp circuit wattage. Use the Usage grid to record the light's usage.
Roadway	A roadway is identified by its roadway type, a unit ID, and the total length. The features that you can attach to a roadway, such as attributes and elements, depend on the roadway type. See Roadway overview.
Segment	A segment is a section of street between two cross streets. Several fields indicate identification information about the segment, such as the street that it is a part of, its segment ID, the cross streets at each end, and its range of addresses. Use the Associated Assets grid to associate other assets with the segment, such as a street sign or sidewalk located along the segment. Other fields indicate structural information about the street, such as its surface type, number of lanes, and percentage of commercial traffic. Use the Components tab to define components of the segment that can be inspected separately.
Sidewalk	Use the Associated Assets grid to associate other assets with the sidewalk, such as street lights and intersecting sidewalks. Several fields indicate structural information about the sidewalk, such as its surface type, length, and amount of pedestrian traffic.
Sign	Several fields indicate structural information about the sign, such as its vertical and horizontal clearances, type of reflective coating, and text. The Light field identifies the light that is attached to the sign.
Signal	The Position field shows the signal's position at the address. The position cannot exceed the maximum number of positions allowed for street signals at the address, and a position of 0 indicates that the signal is not in use. Use the Associated Assets grid to associate other assets with the street signal, such as a sign warning vehicles of the signal or a landscape located near it. Several fields indicate information about the signal's access hole and cabinet, which contains the electronic equipment used to manage the signal, including controllers, monitors, detectors, and modems. Use the Name Plate grid to record data from the signal's name plate, such as its model and manufacturer. Use the Performance Indicators grid to record a performance reading of the signal, such as noting the percentage of LEDs that are expired. Use the Usage grid to record the signal's usage.
Support	A support is a structure that supports a traffic light, street sign, or similar asset. Use the Associated Assets grid to associate other assets with the support, such as a street light or sign that is mounted on the support. Several fields indicate structural information about the support, such as its material and its vertical and horizontal clearances.
Tree	Several elements indicate identification information about the tree, such as its botanical name, its growing space, and whether it should be monitored for clearance around roadways and buildings. The Landscape field indicates the landscape asset where the tree is located.
