Subject: Awaiting Report 2025-11: Improving real-time arrival predictions for EZRide
In response to Awaiting Report 25-11 requesting that the City Manager exert all appropriate influence on
EZRide and Passio to take immediate and concrete steps to resolve tracking deficiencies and improve
real-time transit accuracy for riders, we report the following:
City staff have communicated all concerns regarding real-time arrival predictions to Charles River
Transportation Management Association (TMA) staff who oversee the EZRide service. Charles River TMA
and city staff agree that providing arrival information in real time is important to encouraging people to use
local transit, like the EZRide.
The Charles River TMA and EZRide operator have recently made a number of changes that have improved
overall shuttle service and shuttle arrival predictions. EZride now operates the following service schedule:
•
North Station to/from Cambridgeport via Lechmere and Kendall from 6 a.m. to 8:30 p.m. weekdays
•
Lechmere to/from Kendall/MIT from 9 a.m. to 8:40 p.m. on weekends
These changes were the result of:
•
Expansion of service to all-day weekday service that simplified shuttle routing, operations
management, and dispatching
•
Related modifications to shuttle dispatching and vehicle location information systems that provide
bus arrival predictions
The Charles River TMA staff reported that, in particular, the simplification of three separate routes with
different destinations based on time of day on weekdays into a route with the same destinations all day
has significantly improved reliability of arrival predictions. In particular, the TMA staff believe that the
reduced opportunity for operator, dispatching, or management error is the cause for improvements. TMA
staff gave some examples, like, fewer instances when an operator may be incorrectly “logged in” as active
on out-of-service trips or on a different routing than is the appropriate one for the time of day. They also
stated that they will continue monitoring the accuracy of arrival information.
TMA staff have also engaged continuously with Cambridge constituents responding to concerns or
complaints about shuttle arrival predictions. After the expansion of EZRide service in mid-April, Charles
River TMA and EZRide operations staff have reported that they’ve been able to resolve all complaints
about incorrect real-time information.
