The proposed regional transit plan differs from previous versions by including a new north-south BRT corridor from Greenwood to Carmel, more frequent service on four BRT lines, quicker development of the Northeast Corridor rail line, and additional local bus service. The changes reflect lower growth projections and funding uncertainty. The plan will initially focus on Marion and Hamilton counties but study expansion to other counties. It creates a Metropolitan Transit Authority to oversee regional transit including IndyGo buses and proposes a new tax of 0.3% of taxable income to fund the system.
