Concurrent Flow Lanes – Phase 2

Project 21Phase II of this multi-phase project focused on the development and validation of a simulation model and supporting analysis tools, and their application to a specific segment of I-270 within the State of Maryland as identified by the sponsor.

The primary purpose of this phase was to assess the chosen simulation software platform and modeling methodologies as a potential tool for modeling and analyzing traffic operations, including the specific details associated with modeling concurrent flow lanes with designated access points, along significant portions of the Maryland freeways.

This effort culminated in a fully calibrated simulation model of existing conditions and supporting modeling techniques necessary to replicate vehicular behavior in the presence of both continuous access HOV lanes and limited access HOT lane facilities. Parameters chosen through the calibration effort were employed in additinoal simulation experiments designed to assess the potential benefits of proposed alternative HOT lane facility designs under 2030 demand estimates. The modeling techniques were applied to the southbound lanes of a 7-mile segment of I-270 within the State of Maryland (between the interchanges with I-370 and the I-270 Spurs).
