Going an extra .5 miles from West Medford to Wedgemere for an extra $4 doesnt fit any definition of fair.
Playing devil's advocate:
From an equity standpoint: Crossing from West Medford into Wedgemenere, you're
1) Changing jurisdictions
2) Stepping up about $1m per home in real estate value
3) Leaping up in income
The Zoned fares look nicely progressive (as % of income or trip value) And Wedgemere and Winchester Center are fully-subscribed parkingwise as it is,
suggesting that either their parking or their fares (or both) are underpriced even at Zone 1 from an efficiency standpoint.
The "neighborhood tenure & entitlement" factions also consider this fair--that Medford has (somehow) earned this benefit because the private streetcars ran there and Zone 1A was (somehow) the price of merging the MTA with the B&M Lines to form the MBTA. It aint logical, but the concept of "fair" rarely is.
Would Wedgemere like a lower fare? Sure! Everyone wants fare reform to lower their fare! How would it make transit *better* when the constraint on ridership isn't price, but parking?
I might trade: A lower-fare zone for Wedgemere & Winchester Center *IF* Winchester agrees to build more parking so that transit use can increase as fares fall. Otherwise cutting fares is Wedgemere is just a revenue loss, ridership stagnation, and putting extra $ in the pockets of people who mostly don't need it.
