While previous literature, including for these specific routes, has primarily focused on the impact of toll price generally or on areas more proximate to major cities, this thesis expands the toll price and thus congestion pricing literature by focusing on boundary communities. My key findings are that commuters from more economically vulnerable communities seem to be more willing to trade time to avoid paying tolls and that increased salience of price also leads to an increase in the willingness to make that trade. These findings indicate that policymakers should be wary of the differential impacts that congestion pricing can have on different demographics and should consider potential unintended consequences before making changes that can impact salience.application/pdfenPrinceton University Senior Theses
