Using GIS for Collecting Sign Inventories

Blog_UsingGISforCollectinignInventories.png

The Village of Skokie started maintaining street signs over 30 years
ago. Over time, the inventory evolved from strictly paper/mylar based to
eventually incorporate an Excel spreadsheet with ID’s of signs on the
paper maps. While this has worked in the past, current technology
provides a much better solution for managing the Village’s signs. By
using Geographic Information Systems (GIS), the Village can utilize a
technology that is already used throughout the enterprise. This is
especially helpful considering the Federal government has set dates for
compliance for three (3) major traffic sign maintenance requirements.
The U.S. Department of Transportation requires the following:

January 2012 All agencies will have to establish and implement a sign
maintenance program that addresses the minimum sign retroreflectivity
requirements

January 2015 All agencies must comply with the new retroreflectivity
requirements for most of their traffic signs they have installed,
including all red and white or white and black “regulatory” signs (such
as STOP signs and Speed Limit signs), yellow and black “warning” signs,
and ground-mounted green and white “guide” signs (except street name
signs)

January 2018 All agencies must comply with the new retroreflectivity
requirements for overhead guide signs and all street name signs

In order to meet the requirement for January 2012, the Village began
conducting a sign inventory in August, 2011. Once the inventory is
complete, the Village will maintain the data using GIS and will publish
the data internally for planning, analysis, and maintenance purposes.
