A New Way to Look at MBTA Demographics In 2022, the MBTA launched our rolling “rider census” – a.k.a. the System-Wide Passenger Survey – to better understand who rides the system, and how that shifts over time. While this “census” is not a full technical accounting of every rider, it is our most comprehensive survey […]

Introduction As MBTA ridership continues to recover from its drop in 2020, certain areas of the region are recovering at different rates. This blog post examines spatial patterns in the recovery of ridership across the MBTA’s bus and rapid transit systems. We measured ridership recovery by calculating ridership in the fall of 2021 as a […]

At the beginning of 2021, we took a broad look at ridership throughout 2020 to identify some of the changing trends we were seeing due to the COVID-19 pandemic. We wanted to do this at the end of 2021 as well, but just as things seemed to be reaching a steady state, the rise of the Omicron variant caused another drastic change in ridership trends. These trends steadied out through June 2022, then became greatly impacted by various service disruptions. Therefore, we decided to take a look at ridership again up to June 2021 to explain some of the data and give some thoughts about what we might expect going forward.

How can we understand the demographics of riders across our system, to make equitable transit decisions? Depending on resources available, there are multiple methods transit agencies can use to try to estimate their ridership demographics, both to comply with Title VI and supporting policies and to make better decisions about their system regarding equity. A previous post, “Does U.S. Census Data Predict MBTA Bus Ridership?”, summarizes a project which compared the two most common ways transit agencies can estimate ridership for minority and low-income riders: either by conducting a passenger survey to collect demographic information from a sample of riders or using U.S. census data to estimate ridership based on the residential demographics of surrounding stops and routes. Conducting a passenger survey has been – and as confirmed by this blog post is still – the preferred method to understand rider demographics. However, the MBTA continues to use census data as an estimate for certain applications, as it is more easily accessible and less resource-intensive compared to the rider census survey.

The Massachusetts Statewide Bicycle Survey was conducted over the Summer of 2021 to get a holistic picture of the state of biking across Massachusetts and how it was affected by the Covid-19 pandemic. We were interested in how, when, and why people biked both before and during the pandemic, and how they imagined their biking behavior changing in a post-pandemic world. This survey, which was distributed via flyers, email, and word of mouth in partnership with many community organizations, ended up receiving more than 7,000 responses. The respondents were clustered around the immediate Boston area, but we heard from people in nearly every part of the state, and the breadth of responses allowed us to examine how biking differs from region to region.

The MBTA strives to provide good service to riders, but what does providing “good service” really mean? In this post, we will explore this concept as it relates to bus service. For over a decade, the MBTA has been redefining our approach to “good bus service” to better capture the benefits bus service can provide for our riders. We have refined our approach to understanding and measuring this by incorporating additional benefits that a bus route can provide to both passengers and the MBTA system as a whole.

Thank you for taking our second Station Prints Quiz! Let’s take a look at the answers to see which station matched which prints.

OPMI is proud to release the first-ever MBTA Service Delivery Policy Annual Report.

Here on the Data Blog, we previously posted a station prints quiz where readers were given daily ridership graphs for anonymous stations and tasked with identifying which station the graph belonged to (we also provided the answers). With new travel patterns emerging because of the pandemic, we would like to put our readers’ subway knowledge to the test again with another quiz.

Greater Boston’s makeup has changed significantly in recent years, with shifting demographics, emerging employment districts, increasing traffic congestion, and changing travel patterns. Meanwhile, up until recently, much of the MBTA bus network had not seen any changes since the 1960s. To remedy this, the MBTA created the Bus Network Redesign, an initiative that aims to completely re-imagine the  bus network to better reflect the travel needs of the region and create a better experience for current and future bus riders.

The COVID-19 pandemic has greatly impacted transit use, changing trends that were previously well-established and static over time. These circumstances have necessitated a new look at our data to investigate transit changes in a thoughtful way. This post will focus on how we’re thinking about changing ridership trends…

While we have focused primarily on transit ridership on this blog, the pandemic has significantly affected all transportation modes. One interesting case is the effect of the pandemic on biking. A so-called “bicycle boom” has been observed during the pandemic so far, as bicycle demand seemed to increase greatly throughout Massachusetts…

We are proud to release the 2021 version of Tracker.

Starting in March 2020, the COVID-19 pandemic resulted in a catastrophic drop in ridership – and correspondingly in revenue – for the MBTA. Even as trips began to return on the system during the summer of 2020, the MBTA continued to contend with low levels of ridership and associated budget shortfalls. During the fall of […]

At the onset of the pandemic, the MBTA lost a vast majority of its ridership (and therefore a large portion of its revenue) yet played a critical role in transporting the essential workers that kept the Boston area running. We’ve talked about some general patterns in COVID-era MBTA ridership on the data blog previously (see […]

In our review of the impacts of the COVID-19 pandemic on ridership, we showed the following charts that display average entries at gated stations over the day. This shows us how ridership during the pandemic has been not only lower in volume, but also less focused on the traditional peak times around 8 AM and 5 PM […]

In the past two posts, we’ve given an overview of how ridership changed during the pandemic, both over the course of the year and spatially throughout the system. In this post, we’ll take a look at how patterns of ridership changed temporally on a weekly and daily level.

In 2020 Ridership In Review: Part 1, we took a broad look at ridership on the MBTA in 2020, and dove into the details on which types of passengers continued to ride the system. In this post, we’ll examine where passengers rode the system and how that changed from the patterns we typically see.

Ridership on the MBTA and public transit in general has dropped dramatically as a result of the COVID-19 pandemic. For this series of posts, we wanted to take a longer look at the year to review how ridership changed in three dimensions: by mode, over time, and by location.

While ridership remains far from normal, the return to fare collection provided a natural experiment for learning more about how the system is being used and how passengers respond to fares.

A summer 2020 update on ridership overall, with a particular focus on the work we are doing on the data and technology side to better capture bus ridership.

Due to the current COVID-19 pandemic, many of our usual frequent riders have stopped taking the MBTA. As a result, until service and ridership have begun to return to normal, we will be reporting customer satisfaction differently.

We are proud to release the 2019 version of Tracker.

This year, MassDOT released new Statewide Bicycle and Pedestrian Plans with the goal of increasing the comfort, safety, and convenience of biking and walking for all people. One key piece of both plans is making it easier for people to access transit.

We are excited to announce our new Open Data Portal!

After the unfortunate derailment on the Red Line in June 2019 that drastically affected service throughout the summer, we visualized how ridership on the line had been impacted.

Substitution, as it relates to walkability, is defined here as the propensity at which passengers exclusively choose a particular route over other nearby alternative routes. Substitution explains differences in how passengers choose to access MBTA services.

Studies of walking distances of different subway networks have found that walk distances vary considerably from station to station. In this blog post, we explore how walk distances may vary from station to station in our MBTA network

Public transit is one of many solutions that can help us reduce our collective transportation emissions. One of the ways that the T works to get people out of single occupancy vehicles and onto trains and buses is through our Perq program, formerly known as the Corporate Pass Program.

When you separate buses from mixed traffic, you can both improve the speed of bus travel along the corridor and decrease the variability of run times, both of which make taking the bus a more competitive option with driving, and over time, you can not only improve the experience for passengers but also attract more passengers to the bus. We take a look at how well these interventions have met these goals.

On Monday, December 3, 2018, the walkway that links Independence Avenue in Quincy to the Red Line’s Quincy Adams Station reopened, allowing for the adjacent neighborhood to have an easier and more direct access point to the station.

This post will discuss the methods we use to count riders and trips, and to estimate those we can’t directly count. We will also discuss some of our future plans for improving these estimates and our reporting.

This article analyzes the changes in ridership from fiscal year 14-15.

In the last five years, the MBTA and other large transit agencies across the country have seen drops in their ridership, especially on buses and during off-peak times. This is counter to historical trends; given increased population and economic growth in Boston, we would typically expect ridership to increase.

In this post, we investigate the occurrence of people traveling in groups using a single CharlieCard or CharlieTicket.

This post explains changes to the real-time data feed for heavy and light rail vehicles made on September 12, 2018 impact our reliability performance measure.

Long cross-town routes with multiple transfer/connection options tend to be likely to have different riders along the routes, with relatively few people riding the entire length of the route. We evaluate whether it makes sense to treat these routes as a single service, or at the segment level.

Because service disruptions can be complex and tend to unfold over time, there is a constant trade-off between the timeliness of sending the alert and the accuracy of the estimated length of impact to service. We discovered through customer feedback, including in our monthly satisfaction survey, that our passengers were relatively dissatisfied with our approach.

A key component of transit service planning is offering service to the largest number of people possible. Understanding how much of the population the MBTA currently covers, and where that population is located, is important to understanding how well the T is serving its constituents and where the MBTA should expand or modify its service.

In collaboration with the Boston Area Research Initiative, the MBTA is holding a data challenge to see how students and researchers can creatively use the survey data to answer research questions. The winners of the data challenge will be invited to present their work at the BARI Spring 2018 conference on April 27th, 2018.

The MBTA, working with the Central Transportation Planning Staff, has just completed a systemwide passenger survey to collect necessary passenger demographic data for bus routes and rail stations. This project updates the 2008-2009 dataset and will be used for service planning, ridership analysis, and Title VI equity analyses.
