Students frustrated with new bus schedule App developed to track flu Ian Jaffe The Chronicle This flu season, students’ chances of staying healthy may get a boost from an unexpected source—their cell phones. Researchers at Duke and the University of North Carolina at Chapel Hill have developed a cell phone application—called iEpi—that tracks the spread of the disease and predicts the likelihood of contracting it. Anything that The researchyou can do to ers—Duke statisprevent illness tician Katherine Heller and UNC in a college epidemiologist population Allison Aiello— should be done. tested the app with a group of — Jean Hanson approximately 100 students at the University of Michigan, using Bluetooth, Wi-Fi and mobile connections to track the students’ social interactions. Using this data, along with personal information such as smoking habits, the team developed a model that allowed them to predict the daily spread of influenza between study participants. iEpi represents one of the first times mobile devices and social network modeling have been used to track and predict the spread of disease. “Our ability to collect and analyze this kind of data—in terms of trying to improve health outcomes—is really, really important,” said Heller, assistant professor of statistical science at Duke.

Jesús Hidalgo | The Chronicle Students have not been impressed with the recent changes made to the bus schedule. The changes were supposed to increase the system’s efficiency, especially for central campus residents.

Helen Yang The Chronicle Although Duke Parking and Transportation Services reformed the bus system in the hopes of improving its efficiency, students have criticized the new system since its debut. Students expressed concern and frustration over the prolonged waiting time and confusion caused by the changes, which were implemented at the start of the Fall. Notable among the changes were the removal of the C2 service that circuited between West, East and Central Campus and the addition of the C4—connecting Central to West—and the C5—connecting Central to East. Many students have questioned the new routes, which were added based on PTS-led analyses of passenger

transit data. “It hasn’t really fixed much because the Central bus is still pretty horrible to catch,” junior Sanmi Oyenuga wrote in an email. “Wait time is ridiculous, especially in the evening.” Freshman JaBria Bishop said her patience was tested by one of her first experiences with Duke buses. “The CCX works fine as far as I’m concerned, but one day I was waiting for the C5, and it never came,” Bishop said. “I had to take a C1 and walk all the way to Student Health myself. That was a really big disappointment.” Upperclassmen who experienced difficulty with the previous bus system are also critical of the changes. “The new Central buses are even more infrequent than the old [C2],” senior Chaarushi Ahuja said. “Overall, it’s

now even more difficult to get to class on time. If I want to take the bus to get to Central, I have to budget extra time for the travel. In my experience, having just one C4 running between West and Central has made the commute harder, and walking is now the preferred option.” During weekdays, the C4 runs between West and Central Campus in 15-minute intervals, and the C5 travels between East and Central Campus in 20-minute intervals. Another issue that has contributed to wait times has been the large crowds that regularly form at the East and West bus stops. As part of the new bus system, the C1X—which bypassed Campus Drive stops to directly connect East and
