大多数交通旅行规划器都是基于特定供应商产品的专有系统。随着更多功能组件的加入，系统维护和定期更新交通信息成为交通机构的繁重任务。此外，系统的专有性质使其难以利用地理空间信息和网络技术的快速发展。作者提出了一种基于面向服务架构的开放且可互操作的交通出行规划系统，其原则是重用现有的模块化资源，同时提供用户友好的界面以扩展功能。目标是以松散耦合的方式集成在线可用的地理空间服务（例如 Google 地图）、开源地理空间数据库技术和路径查找算法。该系统是利用威斯康星州沃科夏地铁交通的空间和时间交通数据开发的。通过比较现有威斯康星州东南部公交旅行规划器和路线时间表匹配的输出，验证了研究结果。比较结果表明，新的面向服务的架构为交通出行规划者提供了灵活、高效的机制。该架构利用了快速变化的在线地理空间服务，同时保留了每个交通机构可能独有的行程搜索的核心功能。
The majority of transit trip planners exist as proprietary systems based on particular vendor products. With the incorporation of more functional components, system maintenance and regular transit information updates become burdensome tasks for transit agencies. In addition, the proprietary nature of the systems makes it difficult to take advantage of the rapid advancement of geospatial information and web technologies. The authors proposed an open and interoperable transit trip-planning system based on a service-oriented architecture, with the principle of reusing the existing modular resources, while providing user-friendly interfaces for expansion of functionality. The objective was to integrate geospatial services available online (such as Google Maps), open-source geospatial database technologies, and path-finding algorithms in a loosely coupled manner. The proposed system was developed with spatial and temporal transit data from Waukesha Metro Transit in Wisconsin. Research results were validated by comparing outputs from the existing South-East Wisconsin Transit Trip Planner and route schedule matching. Comparison results showed that the new service-oriented architecture provided a flexible, efficient mechanism for transit-trip planners. The architecture took advantage of rapidly changing online geospatial services, yet maintained the core functions of itinerary search that may be unique to each transit agency.
