If it is underdesigned , bottlenecks that cause delays, lost productivity, or unsafe conditions may arise. Transportation is typically systematic engineering . A system is a set of interrelated parts, called components that perform number of functions in order to mon goals. 8 一、运输对经济发展的影响( Economic role of transportation ) ?生产物质资源需要流通?流通中的运输费用追加至产品价值。 ,发展地区经济 Trips Transportation needs Transportation facility Accessibility Land value Land use 9 二、对社会发展的影响( Social role of transportation) 水路运输→促使城市沿江边或海岸布设和发展铁路出现→内陆城市得以发展公路出现→缩小城乡差异航空发展→促进国际间的交流三、对政治的影响(Political role of transportation) ?中央与地方的联络?国防 10
