Guardrail Terminal
2014-01-27T00:00:00
This dataset contains lines representing guardrail end terminals located on interstates, ramps, state routes, TDOT maintained state park roads, and locally owned NHS routes in Tennessee. This dataset can be queried by either location information, height, or by guardrail end terminal type. These records were derived from vehicle mounted LiDAR sensors and digitally captured photos. This information was collected by Mandli Communications, Inc. under the direction of the Asset Management Division and the Long Range Planning Division. Questions on this dataset should be directed to TDOT.Maint.AssetManagement@tn.gov.
This layer is a cartographic representation of where guardrail end terminals have been installed on all interstates, state routes, TDOT maintained state park roads, and locally owned NHS routes. This information was collected using vehicle mounted LiDAR sensors and cameras and was delivered to TDOT by Mandli Communications, Inc. for TDOT needs. Guardrail end terminal information is also available through the E-TRIMS Maintenance_Feature layer.
