Los Angeles Times: Silver Lake’s ‘Road Diet’ Worked
Using data from the city's traffic sensors, we determined that a reduction in the number of lanes on Rowena Avenue boosted safety without affecting traffic volume.
The City of Los Angeles's controversial "road diet" plan, which narrowed Rowena Avenue in Silver Lake from four to three lanes in 2013, has garnered petitions and protests from upset residents since its inception. But with the help of traffic sensor data and data modeling capabilities, DataScience has been able to determine the actual impact of the project.
In this op-ed, originally published in the Los Angeles Times, Data Scientists Dave Goodsmith and Ben Van Dyke explain what led them to their conclusion that LA's most controversial road diet has had a positive effect, as well as some of the challenges they faced in analyzing that impact.
