Final answer:
Transportation issues such as traffic congestion, accidents, and pollution can make it difficult to make appointments. Addressing these issues through transportation planning and investing in alternative modes of transportation can help alleviate the challenges faced by commuters.
Step-by-step explanation:
Transportation issues that can make it difficult to make appointments include traffic congestion, accidents, and pollution. For example, rush hour traffic in cities like Washington, D.C. often leads to heavy traffic and long delays, which can be frustrating for commuters. Additionally, the associated air pollution and fuel consumption contribute to environmental problems. Inaccessible transportation infrastructure can also pose challenges for individuals with health issues or disabilities. Improving transportation planning, investing in alternative modes of transportation, and addressing infrastructure issues are potential solutions to these problems.
