GIS on the Road: Making Better Decisions on Annual Road Resurfacing Projects

Blog_GISontheRoadMakingBetterDecisions.png

The Village of Glenview is responsible for the maintenance of nearly
167 miles of roadways within its municipal limits. Each year, Capital
Improvements reviews its inventory to determine which streets are in the
greatest need of repair. This is a challenging task because it’s rarely
as simple as picking the roads with the most visible damage. The road’s
overall age, surface and sub-surface condition, and proximity to aging
utility infrastructure all play a role in determining the best use of
limited funding.

GIS provides the ideal platform for this project because it allows
the user to compare this disparate data quickly and accurately. Further,
it allows the user to play around with different criteria to see what
results come from different cutoff values. By using GIS, Glenview was
able to weigh in many more factors, and in turn make better fiscal
decisions based on this empirical data. In the coming years, GIS will
incorporate even more variables into this process. Data such as
locations of repetitive watermain breaks and storm water flooding will
be added in so that road repairs done in one year are not torn up the
next year to deal with below-ground issues. In the future, GIS will
also be used to provide the public with an explanation of how specific
roads were selected for resurfacing in a given year. This increased
transparency will help residents understand why roads that appear to be
in terrible shape seem be ignored.
