Operating Freeways with Managed Lanes

Project Description

The managed lane concept is currently being considered on major freeway projects in Texas cities. As a new concept in operating freeways it has a limited experience base, creating a knowledge vacuum in emerging key areas that are critical for effective implementation. Complicating the effort is the rapid progress of several freeway improvement projects in Texas in which managed lane operations are proposed. The operational experience both in Texas and nationally for managed lanes is minimal, particularly for extensive freeway reconstruction projects. The managed lane projects currently in existence involve retrofits of existing freeway sections within highly fixed access, geometric, operational configurations and established eligibility considerations. There are virtually no projects in operation from which to draw experiential data on the implementation of managed lane freeway sections with multiple operational strategies, including variations in eligible vehicle user groups by time of day. The objective of this research was to address the complex issues involved in alternative freeway operating strategies and to provide TxDOT with practical guidance in the planning, design and operation of managed freeway lanes.
