Different modes tend to be important at different geographical levels.運(yùn)輸規(guī)劃可以包括任何運(yùn)輸方式或多種運(yùn)輸方式的組合。在不同的地理層次上，不同的模式往往很重要。交通規(guī)劃的演變：(P17-18)26-27As a result, the transportation studies concentrated on the pre

Out

27、 of these efforts was developed a concept of transportation planning as a rational intellectual process that moved from defined values, goals, and objectives to concrete decisions.在那個時候，交通運(yùn)輸?shù)陌l(fā)展基本上是沒有爭議的，因此規(guī)劃過程被視為主要由工程師和交通規(guī)劃者執(zhí)行的技術(shù)過程。通過這些努力，人們形成了一個概念，即交通規(guī)劃作為一個理性的智力過程，從定義的價值、目標(biāo)和目標(biāo)到具體的決策。Taking the Unit

Also, beginning at about this time, there began to be negative public reactions to the building of urban freeways.以美國為例，到1960年代，城市交通開始參與政府的工作。同樣，大約從這個時候開 始，公眾對城市高速公路的建設(shè)產(chǎn)生了負(fù)面反應(yīng)。The resulting pol
