Transportation Demand Management (TDM) strategies may include which of the following?

1. Increasing road sizes

2. Car sharing and telecommuting

3. Heavy investment in new transportation infrastructure

4. Limiting access to public transportation

The correct answer is: Car sharing and telecommuting

Transportation Demand Management (TDM) strategies focus on optimizing the use of existing transportation resources and reducing reliance on single-occupancy vehicles. By implementing strategies such as car sharing and telecommuting, organizations and public agencies encourage more efficient use of transportation systems. Car sharing reduces the number of vehicles on the road by providing access to cars for those who may not need to own one full-time, thus decreasing the overall demand for parking and road space. Telecommuting further contributes to this goal by allowing individuals to work from home, effectively removing their commuting needs and reducing peak hour traffic congestion. Increasing road sizes and heavy investment in new transportation infrastructure focus more on expanding capacity rather than managing demand for transportation. This approach may lead to induced demand, where improvements encourage more people to drive, potentially negating the intended benefits. Limiting access to public transportation can also hinder mobility and access rather than manage transportation demand effectively. Therefore, the inclusion of strategies like car sharing and telecommuting aligns perfectly with TDM's objectives of improving efficiency and sustainability in transportation.
