旧金山弗朗西斯科县连锁活动建模过程（SF-CHAMP）是为旧金山弗朗西斯科县交通管理局（SFCTA）开发的，用于为各种规划应用提供详细的出行需求预测。这些应用程序包括制定全国范围的计划，为走廊和项目级评估的微观模拟建模提供输入，交通规划和社区规划。其目的是准确地表示目的地的复杂性和时间和模式的选择，并提供详细的信息，旅客作出离散的选择。这些目标导致开发了一个基于旅游的模型，该模型使用综合人口作为决策的基础，而不是区域一级的汇总数据来源。大多数旅游为基础的模型的九个组成部分估计家庭调查数据的弗朗西斯科，加州，居民只有收集的大都会交通委员会（MTC）的手段。通过使用各种观测数据源对每个模型组件进行校准，然后使用五个时段中每个时段的交通量和过境乘客量数据对完整模型进行验证。该模型被应用为一个集中的模型，结合了从整个湾区（来自MTC的BAYCAST行程表）的旅行，从旧金山弗朗西斯科居民的旅游为基础的模型产生的旅行需求。
The San Francisco County Chained Activity Modeling Process (SF-CHAMP) was developed for the San Francisco County Transportation Authority (SFCTA) to provide detailed forecasts of travel demand for various planning applications. These applications included developing countywide plans, providing input to microsimulation modeling for corridor and project-level evaluations, transit planning, and neighborhood planning. The objective was to represent accurately the complexity of the destination and the temporal and modal options and to provide detailed information on travelers making discrete choices. These objectives led to the development of a tour-based model that uses synthesized population as the basis for decision making rather than zonal-level aggregate data sources. Most of the tour-based model’s nine components were estimated by means of household survey data for San Francisco, California, residents only that were collected by the Metropolitan Transportation Commission (MTC). Each model component was calibrated by using various observed data sources, and then the full model was validated with traffic count and transit ridership data for each of five periods. The model is applied as a focused model that combines trip making from the entire Bay Area (derived from the MTC’s BAYCAST trip tables) with the travel demand from San Francisco residents produced by the tour-based model.
