The construction of the managed lanes facility on the Katy Freeway in Houston, Texas, provideda unique opportunity to meet the needs of motorists by providing a completely new set of accesspoints to and from the managed lane facility, as compared to many similar facilities that arepredominantly retrofit installations. The access points on the Katy Managed Lanes are intendedto provide timely, useful access between the managed lanes and the I-10 general-purpose lanes,at locations that facilitate effective access to origins and destinations beyond the freeway.Researchers investigated operational characteristics of selected access points to assesshow they were being used by motorists. This paper provides an overview of the access points onthe Katy Managed Lanes, a discussion of the field data collected and how it was reduced andanalyzed, and the research team’s conclusions concerning how the access points performedbased on the analysis. The study analyzed the number of ingress and egress maneuvers atselected access points, comparing them to traffic volumes in the managed lanes and adjacentgeneral-purpose lanes, with a focus on the amount of time drivers took to make their maneuversand where the maneuvers occurred within the access points.
