寿命的延长和人口的增长导致了美国社会的老龄化，必须考虑到随着成年人年龄的增长而出现的复杂的口腔健康需求。为了向老年人提供预防和恢复服务，有必要了解老年人使用筛查和治疗设施的情况。本研究采用代理为基础的模型，以探讨通过交通网络的筛选和治疗设施的老年人生活在北方曼哈顿，纽约市的社区。老年人被模拟为社会经济上不同的代理人谁移动沿着一个基于GIS的交通网络，使用交通方式，调解他们的访问筛选和治疗设施。该仿真模型包括四种类型的移动的代理作为简化假设：步行、乘汽车、乘公共汽车或乘货车（即，为老年人提供交通帮助）。这些移动的代理遵循特定的路线：老年人谁乘坐汽车，公共汽车和货车遵循街道道路，而行人遵循人行道。该模型使用户能够一次专注于一个邻域进行分析。老年人的无障碍筛选和治疗设施的空间维度是通过模拟的旅行成本（表示旅行时间或距离）发生在基于GIS的模型环境中，较低的旅行成本筛选和治疗设施意味着更好的访问。该模型提供了一个框架，用于表示在GIS环境中的交通网络的上下文中的寻求健康的行为。
Increased lifespans and population growth have resulted in an older U.S. society that must reckon with the complex oral health needs that arise as adults age. Understanding accessibility to screening and treatment facilities for older adults is necessary in order to provide them with preventive and restorative services. This study uses an agent-based model to examine the accessibility of screening and treatment facilities via transportation networks for older adults living in the neighborhoods of northern Manhattan, New York City. Older adults are simulated as socioeconomically distinct agents who move along a GIS-based transportation network using transportation modes that mediate their access to screening and treatment facilities. This simulation model includes four types of mobile agents as a simplifying assumption: walk, by car, by bus, or by van (i.e., a form of transportation assistance for older adults). These mobile agents follow particular routes: older adults who travel by car, bus, and van follow street roads, whereas pedestrians follow walkways. The model enables the user to focus on one neighborhood at a time for analysis. The spatial dimension of an older adult’s accessibility to screening and treatment facilities is simulated through the travel costs (indicated by travel time or distance) incurred in the GIS-based model environment, where lower travel costs to screening and treatment facilities imply better access. This model provides a framework for representing health-seeking behavior that is contextualized by a transportation network in a GIS environment.
