大客車駕駛者心理－物理行為的跟車模式為大客車縱向防撞警示系統發展與行車安全間隔距離法規訂定的基礎，其相關門檻公式與參數可透過駕駛模擬器之建置與實驗分析來加以建立。本研究鑒於實驗場景的規劃建置為大客車駕駛模擬分析的重要成敗關鍵，因此乃依據所建置完成之大客車駕駛模擬器特性，以高速公路平直路段為範圍，規劃建置大客車跟車心理－物理行為門檻模式之駕駛模擬場景，期能提供後續相關研究的參考，並發展出合乎我國現況之大客車跟車心理－物理行為門檻模式。

　　　　　The car following model of bus driver's psycho-physical behavior is the basis of bus rear end collision warning system (RCWS) development and driving safety spacing rule regulation. The threshold equations and parameters of psycho-physical behavior model can also be developed by the bus driving simulator deployment and the simulation analysis. Since the planning and design of simulation experiment scenario is a key element for the success of bus driving simulation analysis, This study planed and designed the driving simulation scenario for developing a bus car following psycho-physical behavior threshold model on freeway straight road section based on the characteristics of bus driving simulator. The results of this study can be a useful basis for developing the bus psycho-physical behavior threshold model in Taiwan.
