ACTT Workshop: Georgia
I-75 from SR 54 North to Aviation Boulevard - for HOV Lanes

Chapter 4: Conclusions

4.1. Key Items for Evaluation

Over the course of the workshop, the participants made many recommendations regarding the I-75 from SR 54 North to Aviation Boulevard - for HOV Lanes project. The following highlights the key items that GDOT plans to evaluate.

  • Clearly define "success" by prioritizing goals such as environmental objectives, the minimization of impacts to the public and retail sites, safety and congestion, freeway management, etc.
  • Advance the purchase of right-of-way, and build two barrier-separated HOV lanes in the median for safety, operation and enforcement.
  • Perform an operational analysis to evaluate the potential for use of I-20 to I-285 to I-675 as the primary alternate: this would provide for total directional closure and super-accelerated construction. If total directional closure is not deemed feasible, widen the southbound first to provide four lanes for two-way traffic, and close the northbound to traffic; reverse the process once the northbound is constructed.
  • Provide wishbone access from the I-75 HOV lanes to the C-D roads to I-285, as connection between the I-75 HOV lanes and I-285 is imperative.
  • Accelerate the Forest Parkway and us 41 portions of the project. Consider using pre-fabrication, pre-assembly and D-B.
  • Realign Forest Parkway to facilitate traffic flow during construction.
  • Eliminate the slip ramps at JC Penney and Lynwood Drive to eliminate weaving and improve safety.
  • Consider using a half-diamond interchange at Bob White Trail on the north side; this option would require improving local roads first.
  • Improve secondary roads and the connections to the HOV lanes to provide easier access.
  • Conduct market surveys to identify the stakeholders, communities and cultures affected by the project and to determine how best to share information or updates with the public.
  • Utilize market survey results to develop community outreach initiatives during the environmental phase of the project and to further design strategies, measures and themes with the intent to preserve the fabric of the community.
  • Coordinate with local jurisdictions to develop a concept of operations such as origin/destination, short/long commutes, HOV/HOT/commercial lanes, express/through trips, etc.
  • Consider tactics like "countdown to completion," professional endorsements (including professional athletic organizations) and third-party endorsements.
  • Maximize the contributions of technology and people, including wireless communications, NaviGATOR, DMS, CCTV, HERO, a project public information officer, performance-based towing services and pre-defined incident response plans.

4.2. Next Steps

GDOT has already directed the consultant chosen for design to evaluate the HOV lane configurations discussed at the workshop and to use a barrier-separated HOV typical section where feasible. The agency is planning a massive public involvement effort to ensure that adequate public input is received and that stakeholders are well informed before any concept is finalized.

GDOT will continue evaluating the recommendations made from each skill set and determine which ideas or suggestions should be incorporated in to I-75 from SR 54 North to Aviation Boulevard - for HOV Lanes.
