About the Project

Timeline: 2016 – 2020
Status: Planning


How cities and towns manage the streets and signals used by MBTA buses has a lot to do with how fast or slow our buses run. In conjunction with the Better Bus Project, the T is partnering with communities to explore and implement tools that improve reliability and service for customers. 

Here are some features of Bus Priority projects:

  • Creating bus lanes or shared bus/bike lanes during rush hours, giving buses a clear path past traffic 
  • Working on transit signal priority, which gives preference to buses at traffic lights
  • Implementing queue jumps, short stretches of priority lanes that let buses bypass waiting traffic with early green signals


More efficient bus service, including:

  • Fewer delays
  • Faster bus trips
  • More reliable and frequent service
