Abstract
The objective of this research was: to define the criteria for consideration of passing lanes in decisions regarding actions to be taken, and to establish the decision algorithms for consideratiom of the passing lanes in decisions regarding measures to be accomplished on multiple lane divided highways. For these purposes, empirical evaluations were performed on maintenance projects actually performed with known previous condition as well as theoretical derivations of critical condition values. The theoretical derivations of economic limits for inclusion or exclusion of passing lanes during maintenance measures was based on a benefit cost analysis taking into consideration the different long term characteristics of the lanes.
