  1. Calibration of aggregate trip distribution models entails estimation of model parameters, including one or more impedance function coefficients

    聚集出行分佈模型的校準要求我們必須估計模型參數，包括一個或多個阻抗函數系數。
  2. Calibrating the gravity model consists of evaluating the parameters of the impedance function ( or the values in the friction factor table ) so that the gravity model reproduces, as closely as possible, the base year productions and / or attractions and the base year trip length distribution

    校準重力模型就是計算阻抗函數參數（或者摩阻系數表中的值） ，使其盡可能吻合基年產生和吸引，以及基年的出行距離分佈。
  3. Calibration typically entails an iterative process that computes coefficients such that the gravity model replicates the trip length frequency distribution and matches base year productions and / or attractions

    典型的校準在系數計算中通常有一個迭代過程，好像重力模型復制了出行距離頻數分佈，同時匹配基年發生和吸引。
  4. Then this paper formulates a classification method of traffic modes, which accords to relation that different traffic modes affect mutually while moving. based on that classification of various traffic modes, this test proposes a combined modal split and trip distribution model of multinomial modes

    並根據各種交通方式運行時與小汽車流的相互影響關系，提出了交通方式分類方法，以此分類法為基礎，建立了聯合多方式劃分和交通分配模型，進行了等價性和唯一性證明，給出了模型演算法。
  5. All over the world a lot of interrelated research indicate, some problems are confronted and left unsolved in practical circumstances, and theory analysis, so thorough and systematic research on it is necessary, these problems include model split, how to decide threshold of tia and study area, the los for road and intersection, trip generation and distribution, trip assignment etc. because the precondition and situation for tia in abroad are very different from inland, if the overseas tia methods will be applied inland, there must have a series of problems

    國內外大量相關研究表明， tia在理論和實際應用中都碰到一些有待解決的問題，這些問題包括出行的方式劃分、 tia閾值及影響范圍的界定、道路及交叉口的服務水平、交通生成和分佈、分配等，需要從理論上對其過程和方法進行深入、系統的研究。由於國外tia的前提和條件與國內有很大區別，國外tia方法在國內的應用存在一系列問題。
