Boston is Becoming a “Smart City” with ENG Support
By Gabriella McNevin
Ushered in with the 21st century, are challenges that require real technological innovations. The global population is growing and, like magnets, people are moving to cities. According to the UN, by 2030, 60% of the population will live in a city, and by 2050, 70% (source). City officials are taking measures to adapt to the steadily increasing population. Today, Boston is zeroing in on population sustainability issues that threaten driver safety and drain energy: Inadequate road infrastructure and an antiquated repair system.
As part of a multifaceted collaboration to create technology to solve urban problems, the City of Boston and a Boston University-led team of researchers have developed equipment to improve the local thoroughfare, called “Street Bump.”
IBM and IEEE has recognized “Street Bump” as a significant contribution to Boston, and have presented the developers the second place prize in “IBM Students for a Smarter Planet/IEEE Smarter Planet Challenge: Student Projects Changing the World.” The team’s project, entitled,“Street Bumps and Big Data Analytics: Crowdsourcing Our Way to Better Roads,” demonstrates engineering expertise and a commitment to improving the world.
The team of researchers includes graduate students Theodora Brisimi (ECE), Yue Zhang (SE), Wuyang Dai (ECE), Setareh Ariafar (SE) and Nicholas Baladis (MIT). Professor Christos Cassandras (ECE, SE) and Professor Ioannis Paschalidis (ECE, SE, BME) are team advisors. All BU researchers are affiliated with the Center for Information and Systems Engineering.
The project focuses on an iPhone app – “Street Bump” – developed by the City of Boston to collect data on road conditions. The app is used by city employees and many citizens and was designed to facilitate crowdsourcing in collecting relevant road condition data. It uses the iPhone’s accelerometer to detect “bumps” sensed during a trip. The app then transmits the data to the City of Boston. The information can be used to alert repair crews of road damage. The algorithms developed by the BU-led team analyze the data received by the City and classifies the detected bumps into “actionable” and “non-actionable.” Severe bumps like potholes are actionable and can be prioritized in scheduling repairs.
In this work, the team collaborated with The City of Boston’s Office of New Urban Mechanics, which provided actual data from the City’s servers. Office Co-Chair Nigel Jacob and Chris Osgood have echoed the Office’s website saying, “there is a revolution going on in how cities are designed & built. This new focus on technology infrastructure and sustainable design links how a city is built with how it is managed and experienced.”
“Street Bump” is the second smart city application Professor Casssandras has advised that received national attention. The first app, Smart Parking, also won 2nd place in the “IBM Students for a Smarter Planet/IEEE Smarter Planet Challenge: Student Projects Changing the World” competition in 2011.
