It stands to reason that moving more car trips in urban areas to micromobility modes will reduce congestion. New research quantifies this reduction, offering another tool for policymakers and infrastructure planners.
A study from Carnegie Mellon University zeroes in on how micromobility — namely e-bikes — can affect congestion in Seattle, finding that if even 10 percent of short car trips during peak afternoon travel were replaced with micromobility, more than 4,800 car trips would not happen, decreasing vehicle miles traveled by more than 7,300 miles a day, a 2.76 reduction in greenhouse gas emissions.
“The big takeaways are that micromobility could decrease congestion, especially on highly congested corridors. But you’re going to need wide-scale bike lane deployment,” said Corey Harper, assistant professor of civil and environmental engineering at Carnegie Mellon University and one of the authors of the study.
