• Abstract:
  This report presents an investigation of the possibility of lifting HOV/HOT lane eligibility and shoulder ; use restrictions during major incidents on general-purpose (GP) lanes. Using traffic data from FDOT ; Districts 4 and 6, the impacts of incidents of GP lanes on the operation of HOV/HOT lanes were ; investigated. A methodology was developed to determine the appropriateness of diverting the GP ; traffic to HOV/HOT lanes under different incident scenarios. The methodology is theoretically sound ; and can be easily implemented in a spreadsheet tool requiring only a few critical inputs. The project ; also reviewed the regulations in Florida concerning the operations of HOV/HOT lanes and concluded ; that there was no legal obstacle or barrier that prevents opening HOV/HOT lanes to the GP traffic. ; Consequently, a two-stage decision-making procedure was proposed to implement a diversion plan. ; The procedure takes advantage of the existing partnership between FDOT and FHP on incident ; management and should allow quick decision making and ensure the integrity and credibility of the ; diversion policy. Lastly, the feasibility of shoulder use for incident management as well as simultaneous ; use of other freeway management techniques such as variable speed limits and ramp metering were ; investigated.
