Sustainable transportation aims to reduce traffic congestion by promoting alternative modes of transportation, such as public transit, cycling, and walking.

Sustainable transportation seeks to improve the efficiency of transportation systems by reducing energy consumption, emissions, and traffic congestion, while also promoting accessibility and equity.

Driving a gasoline-powered car is not considered sustainable transportation due to its reliance on fossil fuels and its contribution to air pollution and greenhouse gas emissions.

Multimodal transportation refers to the integration of different transportation modes, such as public transit, cycling, and walking, to provide a seamless and efficient travel experience for users.

Expanding highway capacity is not a sustainable transportation strategy as it encourages car dependency and increases traffic congestion, which can lead to increased air pollution and greenhouse gas emissions.

Trip chaining refers to the practice of reducing the number of car trips by combining errands or activities into a single trip, thereby reducing vehicle emissions and traffic congestion.

Abundance of natural resources is not a challenge associated with implementing sustainable transportation policies. In fact, the scarcity of natural resources, particularly fossil fuels, is a driving force behind the need for sustainable transportation.

Transit-oriented development refers to the practice of designing cities and towns in a way that reduces the need for car travel by promoting public transit, walking, and cycling.

Promoting cycling as a mode of transportation reduces traffic congestion by providing an alternative to car travel. It also improves air quality and public health by reducing emissions and encouraging physical activity.

Congestion pricing refers to the practice of charging a fee for driving in certain areas during peak traffic hours to reduce traffic congestion and improve air quality.

Expanding highway capacity is not a sustainable transportation strategy for rural areas as it can lead to increased car dependency, traffic congestion, and environmental degradation.

Intelligent transportation systems (ITS) refer to the use of technology to improve the efficiency and sustainability of transportation systems by integrating information and communication technologies with transportation infrastructure and vehicles.

Promoting walking as a mode of transportation reduces traffic congestion by providing an alternative to car travel. It also improves air quality and public health by reducing emissions and encouraging physical activity.

Transportation demand management (TDM) refers to the practice of reducing the number of vehicles on the road by encouraging carpooling, ride-sharing, public transit, and other alternatives to single-occupancy vehicle travel.

Expanding highway capacity is not a sustainable transportation strategy for urban areas as it encourages car dependency and increases traffic congestion, which can lead to increased air pollution and greenhouse gas emissions.
