For ridesharing success, carpoolers should click
Ensuring that would-be carpoolers are riding with people they actually like could potentially decrease car use by nearly 60 per cent, research from a professor at the University of Waterloo has found.
The research, recently published in Transportation Research Part C, used social media analytics, algorithms and computer simulation to match would-be carpoolers with people driving to work.
“Usually carpooling is about just matching people depending on geographical location and time of schedule,” said Bissan Ghaddar, professor of management engineering at Waterloo and author of the study. “We wanted to include the social aspect into the equation, because it’s always awkward when there is silence in the car, especially if it’s a long commute.”
“We believed that we really needed to look at the social aspect, and our initial data analysis agreed with us.”
In compiling the study, Ghaddar worked with colleagues at IBM and two universities in Italy to analyze the Twitter feeds of potential carpoolers, looking for insights into their personal interests.
They then examined the users’ social circles to see if they followed like-minded friends or sought out people with different views and fed that information into a computer algorithm designed to match carpoolers based on their geo-tagged location, time preferences as well as their personalities.
As a final step, they simulated the impact of their matchmaking using real-world data from Rome and San Francisco. They found that if carpoolers are compatible, people’s satisfaction significantly increased and car use dropped by 57 per cent in the Rome and by 40 per cent in San Francisco.
“This could be a system that could put a dent in gridlock, reduce pollution and make commuting to work more enjoyable,” said Ghaddar. “As a carpooler myself, I can’t overestimate the importance of compatibility.”

Professor named to Fastcase 50; other notes
Research Professor Maura Grossman has been named one of Fastcase's 50 for 2017. Grossman, a professor, author and lawyer, is a faculty member in the David R. Cheriton School of Computer Science.
The Fastcase 50 award "honors a diverse group of lawyers, legal technologists, policymakers, judges, law librarians, bar association executives, and people from all walks of life," says a statement from Fastcase, a legal publisher who has been handing out the award since 2011. "The Fastcase 50 has spotlighted and applauded the most fascinating trailblazers and architects of the future of law and legal technology."
"Grossman is an expert in technology-assisted review (TAR), having written two seminal papers on the use of supervised machine learning for electronic discovery," says the award citation. "Maura used her background as a clinical psychologist and as a lawyer at Wachtell, Lipton, Rosen & Katz to demonstrate that TAR can help attorneys do e-discovery faster, cheaper, and more accurately than manual review. Her 2011 paper, “Technology-Assisted Review in E-Discovery Can Be More Effective and More Efficient Than Exhaustive Manual Review,” established one of the first benchmarks comparing TAR to human review. Her 2014 paper, “Evaluation of Machine-Learning Protocols for Technology-Assisted Review in Electronic Discovery,” demonstrated that continuous active learning (CAL)—a method she developed with Gordon V. Cormack—was the most effective method for TAR. Maura has laid the foundation for more effective, more efficient, and less expensive document review for lawyers, and for the use of AI in the delivery of legal services as well."
Grossman and the other award recipients will be celebrated during the 2017 American Association of Law Libraries (AALL) Annual Meeting taking place from July 15 to 18 in Austin, Texas.
The Library will extend its hours for the exam period starting Sunday, July 23 to Friday, August 11.
The Davis Centre Library will be open 24 hours except Sundays (closed Sundays from 2:00 a.m. to 8:00 a.m.). On the last day of extended hours, August 11, Davis Centre Library will close at midnight.
The Dana Porter Library will be open regular hours Monday to Friday, 8:00 a.m. to 11:00 p.m.; Saturday and Sunday, 11:00 a.m. to 11:00 p.m.
- Service desks and related services will be closed at regular times (Porter at 11:00 p.m. and Davis at midnight).
- Attendants will be present at Davis Centre Library for security purposes. Attendants will also monitor for noise, cell phone use, and hot foods, which are not permitted in the Library.
Looking ahead to the civic holiday on Monday, August 7, the Davis Centre will be open 24 hours, Dana Porter will be open from 11:00 a.m. to 11:00 p.m., and the circulation desks will be open from 11:00 a.m. to 6:00 p.m.
