I-4 “Beyond the Ultimate” Managed Lanes Corridor

CTG staff are part of the consultant team alongside the Florida Department of Transportation staff to improve the Central Florida Regional Planning Model’s (CFRPM’s) modeling capabilities. The latest regional model improvements focused on developing a project-specific travel demand model for the I-4 “Beyond the Ultimate” southern corridor, a 20-mile extension of managed, dynamically tolled lanes containing 12 of the world’s largest theme parks (e.g., Disney World, Universal Studios and Sea World). For this corridor, the team will be using a multi-resolution modeling (MRM) approach to ultimately develop corridor design traffic. The MRM approach involves the development, validation, and application of the regional travel demand model, a dynamic traffic assignment (DTA) model, and traffic microsimulation model.

In this phase, the team refined CFRPM by assessing the potential diversion routes and markets and validated the regional model to AM and PM peak period conditions. The team used innovative-to-Florida approaches that incorporated non-traditional data into the validation metrics, including HERE speed data and AirSage trip data. These refinements directly led into the next stage of the MRM.
