Summary

The Cape Cod MPO voted to endorse state-set PM3 system performance targets including interstate/non-interstate travel time reliability and truck travel-time reliability for 2024 and 2026, following a MassDOT presentation explaining pandemic-era data adjustments and target-setting rationale.

The Cape Cod Metropolitan Planning Organization on March 27 voted to endorse the state of Massachusetts’ system performance targets for reliability, congestion and emissions (PM3), following a presentation by Raissa Kwame of the Massachusetts Department of Transportation.

Kwame described PM3 measures — level of travel-time reliability on interstate and non‑interstate roads, truck travel-time reliability (TTTR), and emissions reductions for CMAQ-funded projects — and explained MassDOT’s approach to setting 2024 and 2026 targets after excluding atypical pandemic years from trend calculations. She said the 2024 interstate reliability target is 74% and the 2026 target is 76%, with non‑interstate and truck-index targets set to improve modestly from prior baselines.

Members asked whether region-specific targets would be more useful for Cape Cod. Staff explained MPOs may adopt state targets or set region-specific targets but that Cape Cod’s limited project portfolio makes adopting statewide targets the practical approach; endorsing statewide targets also enables their inclusion in the Regional Transportation Plan and the TIP. Harold Mitchell moved to accept the targets; Pamela Hasner seconded, and the motion passed on a roll-call vote of present members.

The endorsement means the targets will be included in the MPO’s near-term planning documents; staff said they would continue to bring region-level congestion and congestion‑management details back to the MPO for discussion. The vote was procedural endorsement of state targets rather than adoption of a Cape-specific target set.
