This paper considers key issues in operational effects of geometrics at the turn of the millennium and emerging issues that will become increasingly important. History tells us that at some times and in some modes of transportation less than 100 years is needed for a revolution to occur. It was only about 65 years from the Wright brothers' first flight to the landing on the moon. Looking back, the changes in the highway system in the past 100 years have been revolutionary, whereas the changes in the highway system in the past 50 years have been more evolutionary. The members of the Committee on Operational Effects of Geometrics consider it likely that such evolutionary changes in highway transportation will continue. In this paper, the Committee will look at some key anticipated changes and trends and their relation to the traffic operational and safety effects of highway geometrics.
