2010 Managed Lane System Plan (MLSP)

The Managed Lane System Plan (MLSP) is the first comprehensive system-wide evaluation of urban area managed lanes performed in the United States. GDOT believes that in most locations it is not feasible to construct additional general purpose lanes to meet current and future needs. Therefore, GDOT has developed the MLSP for Metro Atlanta that will utilize and expand the current HOV system footprint. Managed lane solutions would preserve mobility choices and provide financially feasible improvements. The study was conducted by the Georgia DOT between January 2007 and January 2010.

Purpose & Goals

Urban area traffic congestion presents a challenge to the continued growth and economic prosperity of the Atlanta region. Future job creation and economic development are inextricably linked to investment in infrastructure that improves mobility, and in order to maintain its competitive edge, there must be continued focus on improving Metro Atlanta’s transportation network.

The provision of managed lanes in the region would ensure that mobility will be preserved even with projected population and employment growth. The purpose of the MLSP is to provide a comprehensive roadmap for GDOT as they move forward with this innovative approach to urban area mobility. More specifically, the MLSP seeks to address the following:

  • Respond to transportation needs which have outpaced traditional revenue sources
  • Unite managed lane investments into a comprehensive “system plan” framework
  • Provide a valuable and reliable mobility option, in spite of congestion; and
  • Lead and tackle policy and implementation issues


Analysis Process

GDOT has taken a comprehensive approach to its evaluation of managed lanes for Metro Atlanta. Through a multi-step analysis process, a range of alternatives has been studied to determine the optimal solution for a regional network of managed lanes.

  • Data collection, including traffic counts and surveys
  • Identification of candidate corridors
  • Planning-level traffic and revenue analysis
  • Concept and operational analysis
  • Social and environmental impact analysis; and
  • Financial feasibility
