about smaty cities smart city boston long

Boston is the capital and most populous city of the Commonwealth of Massachusetts in the United States, and the 21st most populous city in the United States. The city proper covers 49 square miles with an estimated population of 694,583 in 2018, also making it the most populous city in New England.

The City of Boston is using technology to re-imagine its streets. On smart streets, we use technology — like cameras and sensors — to learn more about how people navigate and interact on and with the City’s streets. Our most recent work focuses on roadway safety.

Boston is a leader in the global Vision Zero initiative. The goal of Vision Zero is to end fatal and serious traffic crashes. To do this, we will use technology and data to better understand how people act on roads. That data will help us improve street design and safety.

As part of our Vision Zero effort, we’re working with Verizon to test data gathering technology at the Massachusetts Avenue and Beacon Street intersection.

We are working with Verizon to test several smart cities’ services. Our goal is to capture aggregated data that helps us better understand the hazards on our roads. We’ll use this information to decide on what changes we need to make. This could include:

  • better streets, sidewalks, or signage
  • changes to how we enforce traffic rules, or
  • more in-depth public education.
  • Street as part of our Vision Zero program.

The data required to fulfill zero-mission

how vehicles and cyclists move — left, right, through, and u-turns — during different traffic signals (green, yellow, and red)
vehicles staying in the intersection for long periods of time

pedestrians crossing the intersection when traffic signals say “Walk” and “Don’t Walk,” and where they cross using crosswalks

vehicles and cyclists yielding to pedestrians within crosswalks, and

cyclists’ use of bike lanes and situations that cause cyclists to ride outside the bike lanes.

We are capturing counts and data over time to help us better understand what’s happening on our roads. We are not going to use this information to issue tickets or enforce traffic laws, or keep any records linked to individual people or vehicles.

Smart parking in the city of Boston

In the winter of 2013, we launched a smart parking initiative in Boston’s Innovation District with the Boston Transportation Department.

This effort was part of the Complete Streets initiative. The goal was to give potential drivers real-time parking information. This would allow them to find parking — or instead — take another form of transportation.

Lots of congestion and air pollution is tied to drivers circling neighborhoods to find parking, as researcher Donald Shoup notes. At the same time, more drivers are relying on real-time navigation from on-board systems or their smartphones. Similarly, we were looking to connect drivers with vacant spots by giving them real-time information on open spaces.

The experiment

Our hypothesis? Giving information to drivers about available parking spaces will help reduce congestion. We’ll do this by shortening the time it takes to find a space, or by encouraging a person to another way to travel. In the winter of 2013, the City partnered with Streetline to put sensors in its first of two neighborhoods:

  • We sunk these hockey puck-sized sensors flush to the surface of the road to detect open parking spaces.
  • We then made that information available via the Parker App, Streetline’s custom websites, and its API.

The City first installed 330 sensors in the Innovation District, a fast-growing neighborhood. This area has put a special emphasis on being an urban lab for testing new technologies.

Results and Lessons Learnt


The project gave the Boston Transportation Department a wealth of real-time data on parking data. Using this information, they experimented with adjusting policies to improve the parking experience in the pilot area.


One of our main goals was to give researchers and other app developers access to the data. A start-up from MIT and a researcher from a local university are both exploring how best to use this data.


There is excitement from drivers about the service, but it’s too early to know how effective it’s been.


Smarter, more efficient resource allocation for the City of Boston streets.

The Transportation Department’s new Mobility Team, in partnership with New Urban Mechanics, is working to:

  • expand the Drive Boston program to provide over 150 new locations for car-share in Boston neighborhoods
  • install electric-vehicle charging stations in municipal parking lots
  • monitor an ongoing pilot of pickup and drop-off zones for rideshare companies to minimize traffic disruptions, and
  • develop a Shared Mile Playbook of principles to navigate the new technology-driven and on-demand landscape.

Boston was selected as an American Climate Challenge city by Bloomberg Philanthropies in 2019 to showcase its progress. Below, projects that are “in implementation” are linked to their respective webpages.


  • Exploring new approaches for community-led innovation in public spaces.
  • Sensors are not smart. Digital kiosks do not save the world. Efficiency is not a democracy.

We think a truly smart city is one that creates equal opportunities for people to connect with each other and with the world. It allows its residents to decide what their definition of “smart” should be, and what creates real civic value. It provides ample pathways for its people not just to optimize it, but to live in it. It’s not a laboratory. It’s home.

Beta Blocks is a new civic experimentation process to build more meaningful relationships between communities that have a challenge and the companies, researchers, designers, and artists who might be able to offer a hand.

The Beta Blocks Action Research project is responding to the following challenges:

  • The lack of public dialogue around the civic values and privacy concerns of smart city tools.
  • The lack of clear and dynamic processes and policies for civic experimentation.
  • The inability to easily “plug-and-play” new tools and designs in the public realm.
  • We want to “open source” City streets. But Beta Blocks is not some expansive deployment of sensors or gadgets. It’s an invitation for all to help us dream up what’s next around the street corner, and how we hold ourselves accountable.

The City and its partners plan to do the following over the next couple of years:


We need to create a strategy for engaging the public in how we conduct experiments in Boston’s streets. We want to level the playing field so all have the knowledge to advocate for, or push back, on a project.


We need to create more opportunities for the public to give feedback on the City’s tech policies. This includes exploring a “public privacy policy.” We want to be clear about the rights our residents have over their own data in the public realm.


We want to ground discussions about process and policy in real-world scenarios. We aim to work with communities around Boston to deploy innovative street-level improvements.


We want to explore the creation of a “clearing house,” “matching platform,” or “exchange” for civic experiments. We know that community groups have a lot of questions, challenges, and ideas. And we know that researchers, startups, and designers have lots of solutions they want to test. How can we bring the two together?


The Beta Blocks project should result in new, dynamic policies around how the City sources and permits civic experiments.


We’re dedicated to making Boston’s streets safer, more efficient, and more delightful. Through our Streets work, we want to improve the flow of people throughout the City with:

  • smart and more accessible street furniture
  • parking systems that limit congestion, and
  • safer roadways for cyclists.

We work with the Mayor’s Streets Cabinet, the Transportation Department, and Public Works. We want to understand how people are moving through our urban landscape and design new pathways to help them.

Zero deaths, injuries, disparities, emissions, stress. This is Boston’s vision for our transportation future.

Autonomous vehicles offer immense promise to help us get closer to these goals. However, the promise of these vehicles isn’t a given. They could displace an important workforce and encourage both sprawl and congestion. That’s why we launched an autonomous vehicle testing program.

We want to shape the development of technology and policy to deliver on the potential promise — and not the potential drawbacks.


The overwhelming majority of crashes on our streets are caused by human error. The promise of autonomous vehicles is to eliminate up to 90 percent of those crashes.


Who stands to benefit most from this technology if it’s applied the right way? Many people, including:

  • the aging population and those with visual impairments
  • those looking to reduce the burden of personal vehicle ownership, and
  • those without access to rapid transit.


We can reduce the number of vehicles on our roadways through the adoption of shared fleets of autonomous vehicles. This frees up space for other uses, other travel modes, and creates more predictable travel times.


We are taking a graduated approach to AV testing in Boston. At first, any company will be constrained in the time, place, and manner of their testing. Before testing on streets, companies must meet — off-street — our important standards, including:

  • ease of manual takeover from autonomous mode
  • emergency braking and emergency stop functionality, and
  • basic driving capabilities, such as staying within a lane.

Currently, vehicle testing in Boston includes the use of a safety driver focused on roadway activity. There is also a safety engineer monitoring the vehicle’s software.

Boston Autonomous Vehicle Testing

For our initial on-street testing, we will keep autonomous vehicles driving to just a few blocks. These streets are within the City’s Flynn Marine Park in the Innovation District. After meeting the test plan milestones, partners will expand out of the Marine Park in subsequent phases.

The majority of testing is occurring in the South Boston Waterfront. Optimus Ride is approved to test in this region of the City. Aptiv has the approval to begin mapping additional neighborhoods in the City. As of July 2018, Aptiv has begun high-definition mapping in new areas of the Seaport and South Boston.


We believe that safety is paramount in the testing of autonomous vehicles.


Vision Zero Boston is the Boston Transportation Department’s commitment to focus the City’s resources on proven strategies to eliminate fatal and serious traffic crashes in the city by 2030. We are inspired by the belief that even one fatality is too many.

While Boston has a relatively good record on traffic safety compared to many other cities, Mayor Walsh is not content to accept 20+ fatalities and 200+ serious injuries on city streets every year. Death and serious injury are not part of the cost of doing business in a busy city. That’s why the Boston Transportation Department launched Vision Zero Boston.

Vision Zero Boston looks behind the statistics at:

  • the human and economic cost of traffic crashes
  • the barriers created by busy, high-speed roads in the heart of our City, and
  • the impact of speeding on neighborhood streets that can limit access, mobility, and opportunity in communities that need it the most.

Vision Zero Boston makes traffic safety personal. Bostonians are going to meet the victims of serious traffic crashes and the family and friends of people killed on our streets. These are not just statistics, and traffic safety isn’t someone else’s problem.

Vision Zero Boston prioritizes safety and takes a people-first approach to transportation and community building. Most trips in the City of Boston are made by people on foot, bike, or transit. Everyone, including drivers, benefits from a transportation system that’s made safer for the most vulnerable road users.

Boston’s Safest Driver is a smartphone app that provides you helpful feedback on your driving based upon five metrics.
