SEMCOG Pavement Condition Map:

This map shows pavement condition using the PASER rating criteria. The 2017-2018 condition shows the latest available rating for the road segment.

You can query data using the dropdown buttons above or click on a segment to get detailed information.

Lane and centerline miles represent the approximate rated miles on federal aid link segments in the current map view only. This number should be used as an approximation of lane and centerline miles.

Instructions:

  1. To acquire road condition data and additional information about a road segment, zoom into the segment and click on it.
  2. To disable autozoom, uncheck the box under the search icon in the top left corner of the map. This will keep map at desired extent as you change filters.

Definitions:
Centerline miles: length, in miles, of a roadway.

Lane miles: the centerline length of the road in miles times the number of travel lanes striped on the segment of road; a lane mile also may be defined as one mile of roadway that is designated as a driving lane.

PASER rating Detail Definition
Good 8, 9, and 10: New or like new road; only requires regular maintenance.
Fair 5, 6, and 7: Road surface shows some wear or aging; prime candidates for capital preventive maintenance such as crack sealing or a thin overlay to prolong the life of the road.
Poor 1, 2, 3, and 4: Road surface reaching the end of its life; most cost effective repairs include rehabilitation and reconstruction.

National functional classes Detail Definition
- Interstate: limited access
- Other freeway: limited access with features of interstate.
- Other principal arterial: connecting routes between cities.
- Minor arterial: shorter trip distances.
- Major collector: routes which funnel traffic from minor collectors.
- Minor collector: routes with more through traffic.

Note: 2003 to 2006 PASER Ratings were collected on 100% of federal aid roads for the year. Beginning in 2008, the federal aid system was divided in half, and collection of the entire system was conducted over a two-year rating period. Since that time, 50% of the system has been collected each year.
