Region 1 


Overall Pavement Condition

The charts below reflect the historical and forecasted system pavement condition for Region 1. Collected data represents condition based on tenth mile IRI in the positive route direction. Forecasted years represent condition at the pavement section forecasted from dTIMS. Condition data was not collected in 2013 and 2016 and is interpolated in the charts.

High Volume Condition

High Volume pavement relates to roads with 1,000 or more cars a day. In Region 1 this system contains 715 center line miles and 3,615 surface areas. Region 1 funding for the High Volume System is $35.2 million.

Low Volume Condition

Low Volume pavement relates to roads with less than 1,000 cars a day. In Region 1 this system contains 255 center line miles and 610 surface areas. Region 1 funding for the Low Volume System is $7.2 million.

Sustainability Index - Draft

The Sustainability Index is a draft performance measure. The Sustainability Index will be the ratio of the work done (planned) to the work required – measured in units of surface area years.  This Index will provide an indication of our future condition.  Values less than 100% would forecast a decline in condition, while values greater than 100% would forecast an improvement in condition.
