Fairfax County established Transportation Demand Management (TDM) requirements (“proffers”) for new development that would have significant traffic impacts. For buildings within the urban centre of Tysons, trips had to be reduced between 25% and 65% during peak hours, depending on the size of the building and its proximity to the Metrorail stations. The county proffers required large new properties to annually monitor trips, conduct tenant commuting surveys, and show that they were meeting their trip reduction goals. They also had to conduct surveys every three years. Over seven years, 13 such developments generated 63% fewer trips, which was 34% beyond their goals. For the office buildings, this was likely at least partly a result of more people working from home during the COVID pandemic.
