註釋The traffic impact assessment methodology developed in dissertation research integrates land use, travel demand, and transportation network modeling to quantify each component of the traffic impact on the highway network providing access to the new land development. The modeling procedure is accomplished in a iterative process over eight modeling phases, and involves a feedback loop between travel demand and network model, and the corresponding land use model for a given geographic region. The methodology calculates incremental VMT associated with each component of the transportation impact, and thus can ascertain corresponding transportation costs if the cost of VMT is known. Using the appropriate formula, each cost component (direct, indirect, and induced) can be allocated to either the local community (to be paid from local taxes and development fees) or the regional traveling public (to be paid from regional transportation funds, such as proceeds from the gas tax). The methodology was demonstrated in a case study of a hypothetical land development in a local community and a corollary highway improvement in a medium sized metropolitan area. A sensitivity analysis was also conducted to evaluate response of the modeling procedure to changes in in key input parameters.
