Concurrent Flow Lanes: Phase 3

Modeling techniques and results from prior calibration and other efforts will be directly applied in creating a set of simulation models (including existing conditions and alternative designs) of all of I-270, including portions of I-495 in both Maryland and Virginia. This set of models will enable comprehensive evaluation of proposed concurrent flow lane design alternatives, including access point design and potential geometric design changes (e.g. related to ingress/egress) to alleviate identified bottlenecks, as well as sensitivity analysis studies related to, for example, demand estimates, violation rates, or HOV/HOT lane facility usage.
