The paper describes the formulation and calibration of the access and land development trip distribution gravity model (ALDGRAV) for use in highway planning at a subregional level. The model is being used as an element of the thoroughfare analysis process (TAP), which, in turn, is one module of the thoroughfare planning system (TPS). TPS has been developed by the North Central Texas Council of Governments, in close cooperation with the local governments, to answer present planning need, in particular to provide tools for orderly, inexpensive, and fast response evaluation of small- and medium-scale strategies. TAP provides the analysis capabilities of the system. The paper introduces the hierarchy of objectives, design requirements, and the resulting design decisions of TPS, TAP, and the ALDGRAV trip distribution model. A detailed description of the latter is given. /Authors/
