A study was conducted to determine the economic benefit of trees in unprotected highway medians. A representative segment of highway median on Interstate-290 in Central Massachusetts was chosen for analysis. Several years of accident reports involving collisions with trees located within the project site were collected, and a field survey was conducted to gather physical data. Using models that estimate societal losses due to accidents and the value of trees respectively, the economic benefit of trees in unprotected medians was determined.
