Arlington Police offered no other details about the crash or the victim's condition, except to say that the crash remains under investigation.
Earlier this month, Arlington's Select Board voted to convene a new design review committee "to study and make recommendations for both short term and long term improvements to the intersection of Massachusetts Avenue and Appleton Street."
A considerable amount of work on that subject has already been done. In 2011 and 2012, the Boston Region Metropolitan Planning Organization, citing "the relatively high number of crashes at this intersection and students’ safe access to Ottoson Middle School," conducted a detailed study of the same intersection.
The report proposed two possible reconfigurations for the intersection, both of which would have shortened its crosswalks, simplified traffic patterns, and reduced the intersection's paved footprint.
Those recommendations were never implemented.
Daniel Amstutz, Arlington's Senior Transportation Planner, warns that large-scale projects to realign the intersection are likely to take years to finance, engineer, and build, but said that "we may be able to do some tactical improvements for the geometry" in the meantime.
"There may be short-term improvements we could do with paint and pavement markings," said Amstutz in a phone interview on Tuesday. "We would need to determine if that’s a way we want to go, and then figure out what it would cost."
