Runway Exit Design Interactive Model V3 (REDIM-V3) REDIM is a computer model developed to locate and design high-speed runway exits at airports. The model uses kinematic equations to characterize the aircraft landing dynamics and a polynomial-time dynamic programming algorithm to find the optimal locations of the high-speed exits. The objective of the optimization algorithm is to minimize the weighted average runway occupancy time (ROT) of an aircraft mix selected by the user. A database of aircraft characteristics for four terminal Aircraft Approach Categories (AAC) has been included in the model to facilitate its use in a large variety of airport environments and conditions. The database file relieves the user's data-input burden, specially when the aircraft mix consists of many different types of aircraft. The program is developed to be used as a design and a planning instrument by engineers. Hence, considerable effort has been devoted to user interface such as menu system, interactive data editing, and graphical and tabular outputs. 6/18/2020
