Man-Made Môi trường: Giao thông vận tải Các yếu tố vận chuyển như giao thông và bãi đậu xe nên luôn luôn được xem xét trong việc chuẩn bị của một tuyên bố NEPA. Trong một số trường hợp, giao thông vận tải hiện có và tác động khi nó có thể là yếu tố quan trọng trong nghiên cứu, ví dụ, các tòa nhà lớn và các cơ sở tại các khu vực đô thị. Trong những người khác, các vấn đề vận chuyển có thể tương đối nhỏ. . | 13 The Man-Made Environment Transportation Transportation factors such as traffic and parking always should be considered in the preparation of a NEPA statement. In some cases the existing transportation and the impacts upon it may be major factors in the study for example large buildings and facilities in urban areas. In others transportation issues may be relatively minor. The basic points to be considered include answers to the following questions Are there adequate transportation and parking modes presently in existence to bring workers to the project site What will be the effects on existing transportation systems Will new transportation facilities be required The discussion should focus on the effects on such things as public transit systems capacities and constraints vehicular congestion capacity of existing roads safety considerations adequacy of parking and so on. A new project can impact transportation systems in several ways Construction and operation may place increased and perhaps unattainable demands on existing transportation systems. Operation may generate a demand for new facilities . noise barriers parking facilities etc. . Construction and operation may permanently displace certain transportation routes. Location and operation of the project may reduce transportation accessibility and access to other facilities and services. To evaluate these potential impacts a number of techniques are used to quantify existing levels of service and to document impacts which might result from the construction of the proposed project. Typically the starting point is an inventory of the situation in the proposed study area including roads public transportation and parking facilities. These inventories are completed through a review of community maps and plans capital improvements budgets interviews with local officials field surveys and contacts with state regional and local agencies. The inventory then is compared to accepted national or local standards for .
