The following snow and ice formula computations were prepared utilizing the current snow and ice formula (latest change was in 1983).
In March of 1986, all maintenance areas were requested to update their input data for the snow and ice formula for the upcoming winter season (1986-87). In addition, projections for the next five (5) winter seasons were asked for based upon the following:
1. Projected increases in lane miles and interchanges by an assumed completion date through new construction or jurisdictional changes. All these changes were itemized.
2. Changes in classification due to an increase in traffic volume. An increase of 2% per year was allowed.
The data received was inputed into a computer program to generate the tables which follow.
