Wisconsin Department of Transportation - Wisconsin State Highway Curb Ramps and Sidewalk ADA Inventory Database

Description:

This application provides a tool for users to view the currently identified inventory of curb ramps, sidewalks and shared use paths along the State Trunk Network (STN) including connecting highways in Wisconsin. This inventory is not complete and consists of locations identified as part of a desktop inventory using aerial imagery as well as curb ramp locations that have been field located and checked. The Curb Ramp Desktop Inventory contains data on curb ramps
locations, sidewalks and shared use paths along the State Trunk Network (STN) including connecting highways in
Wisconsin. The desktop inventory was developed in 2014/2015 using WisDOT Photo
Log and Google Earth satellite images. It is recognized that there are gaps and
limitations in the data, for example interstate interchange curb ramp locations
may not be identified where they intersect local roadways. A desktop inventory
data validation effort determined that the initial Desktop Inventory may have
been missing about 8% of the existing curb ramp locations. 

In 2019, DTIM implemented a process to field verify curb
ramp locations and characteristics (widths, slopes, etc.). Field data is
collected through Curb Ramp Location Post Construction Reports (PDF) and using
the ADA Curb Ramp Data Collection (AGO) application developed by DTIM. As ramps
are field checked they are added to the Curb Ramp Field Checked data layer.
Curb ramp locations that have been field verified are then removed from the
Desktop Inventory layer as part of a yearly update process, typically in the
spring following the previous construction season.Together the Curb Ramp Desktop Inventory and the Curb Ramp
Field Checked data layer provide a statewide snapshot of currently identified
curb ramp locations on the STN.It is not recommended to use the Curb Ramp Desktop Inventory
for project design or construction. The Curb Ramp Desktop Inventory data is
suitable for providing an estimate of the number and locations of curb ramps on
the STN when used in combination with the Curb Ramp Field Checked data layer. Note: Detectable warning fields refers to curb ramps with truncated domes.For questions contact DOTCurbRampDataCollection@dot.wi.gov
