The need for timely and effective dissemination of traveler information in rural areas is underscored by the disproportionately high percentage of traffic accidents and other incidents, exacerbated by the relatively long trip durations and lack of reliable and comprehensive communications infrastructure along the roadways in these areas. Technical and structural approaches that are prevalent in metropolitan areas simply are not feasible for rural settings. This research explores alternative technical and structural approaches to effectively disseminating traveler information in rural areas. A systems engineering approach is used to incorporate technologies and methodologies from diverse disciplines. Peer-to-peer communications between vehicles and between vehicles and roadside sensors, using recent advances in wireless technologies and ad hoc networking protocols are explored to serve as a surrogate for extensive fixed communication and information infrastructure. Human factors and inputs from private and public sector stakeholders are used to further shape the system design. Emerging technologies such as smart antennas are evaluated using requirements-based criteria and an end-to-end system design. Modeling and simulation techniques are used to conduct performance assessments and technology trade-off studies. An outcome of this research will be the design of a prototype that might be deployed in a rural area for a field trial.The results of this research will direct future investments in communications and information technology infrastructure that will suit the particular demand of rural and sparsely populated areas. The approach provides a high benefit to cost ratio that meets the structural requirements of large portions of the less populated regions of the country. The benefits go beyond improvements in safety and efficiency, as the infrastructure also supports a broad range of traveler information services that are of value to businesses that rely on transportation, such as fleet management, as well as the broader tourist industry. The project is highly multi-disciplinary, incorporating expertise from the electrical and computing engineering as well as the transportation sector. Students involved in several facets of the work engage in research that cuts across traditional departmental boundaries. The potential that this project provides to minorities such as Native American communities is extremely high, as the lack of adequate communications and information infrastructure in their areas will be directly and positively affected by the outcomes of this research.

农村地区交通事故和其他事件的比例高得不成比例，而这些地区的道路上行车时间相对较长，沿着缺乏可靠和全面的通信基础设施，使情况更加恶化，这突出表明需要及时有效地传播旅行者信息。在大都市地区流行的技术和结构方法在农村地区根本不可行。本研究探讨了在农村地区有效传播旅行者信息的替代技术和结构方法。系统工程方法用于整合来自不同学科的技术和方法。对等通信车辆之间和车辆和路边传感器之间，使用无线技术和ad hoc网络协议的最新进展，探索作为广泛的固定通信和信息基础设施的替代品。人的因素和私营和公共部门利益攸关方的投入被用来进一步塑造系统设计。智能天线等新兴技术使用基于需求的标准和端到端系统设计进行评估。建模和模拟技术被用来进行性能评估和技术权衡研究。这项研究的成果之一将是设计一个原型，可在农村地区进行实地试验，这项研究的结果将指导今后对通信和信息技术基础设施的投资，以满足农村和人口稀少地区的特殊需要。该方法提供了一个高的成本效益比，满足该国人口较少地区的大部分结构要求。其好处不仅仅是提高安全性和效率，因为基础设施还支持广泛的旅行者信息服务，这些服务对依赖运输的企业（如车队管理）以及更广泛的旅游业都有价值。 该项目是高度多学科的，结合了电气和计算工程以及交通部门的专业知识。参与工作的几个方面的学生从事跨越传统部门界限的研究。这一项目为美洲原住民社区等少数群体提供的潜力非常大，因为他们所在地区缺乏适当的通信和信息基础设施，这一研究结果将直接产生积极影响。
