Description
The purpose of this report is to give an overview of the number of Minnesota agencies that use Infrastructure or Pavement Management software and provide information as to their common components and requirements. Software of this type is used to store and analyze the various components of an agency's infrastructure. This might include such things as streets, highways, bridges, signs, utilities, etc. Most systems of this type are capable of data storage, retrieval, analysis and forecasting or projecting future conditions and need for maintenance. A Federal Highway Administration policy, issued January 13, 1989, requires all states to have a fully operational Pavement Management System (PMS) within four years of the issuance of the policy. As more and more states implement a PMS, the number of county and city agencies will also likely increase. This report reviews the current status of Minnesota cities and counties in terms of their implementation and use of software of this type.

Description
Gravel roads are common in rural Minnesota. While these roads are sufficient for ordinary low-volume traffic, gravel surfaces offer poor traction and bumpy driving; traffic generates dust and gradually displaces gravel. These roads may also be damaged by heavy farming equipment and other rural industry transportation.
