Athanasios K. ZiliaskopoulosNorthwestern UniversityNSF/USDOT : A Zero Infrastructure Vehicle Based Traffic Management System This research project introduces and studies an innovative, fully decentralized traffic information system that is based only on data exchanged by equipped vehicles. It does not require any infrastructure to be installed on the network by government agencies. Vehicles exchange traffic information as they move through the network, which allows drivers to adjust their routes and avoid or be prepared for congestion, incidents or other hazards. Since the system is solely based on in-vehicle devices, it will be market-driven and self-maintained and it will work on all types of roadways, if there is sufficient market penetration (freeways, arterials, rural and dirt roads). It will be upgraded as newer cars, with more advanced technological capabilities for obtaining, exchanging and processing information, are introduced into the market-similar to the to that of the computer hardware and software industry today. While the concept is outside of the current policy philosophy of government agencies, the investigated system is quite simple: participating vehicles equipped with on-board computing and communication devices will be able to determine the vehicle's current location and past spatio-temporal trajectory as they traverse the network and exchange traffic measurements with other equipped vehicles. Equipped vehicles moving in opposite directions on the same roadway or at intersections will exchange traffic information. This research will use analytical probabilistic and simulation based methods to answer questions, such as what is the necessary market penetration to have effective information generated and propagated throughout a street network, the relationship between shockwave and information-wave propagation, and the functional and algorithmic requirements of online routing algorithms to convert the data exchanged into meaningful routing information. The analysis will consider benefits for equipped and non-equipped drivers under various scenarios of recurrent and non-recurrent congestion. If the above analysis demonstrates potential for significant benefits, we intend to work with major communication and auto manufacturing companies that have strong ties with Northwestern University to develop a preliminary assessment of the technical feasibility of the system and potentially deploy a pilot.

Athanasios K. Ziliaskopoulosnorthwestern Universitynsf/USDOT：基于零基础设施的交通管理系统，该研究项目介绍并研究了一种创新的，完全分散的交通信息系统，仅基于配备工具交换的数据。它不需要政府机构在网络上安装任何基础架构。 车辆在通过网络移动时交换了交通信息，这使驾驶员可以调整路线，避免或准备为拥塞，事件或其他危害做好准备。 由于该系统仅基于车载设备，因此它将是市场驱动和自我维护的，如果有足够的市场渗透（高速公路，动脉，农村和土路），它将在所有类型的道路上工作。 它将作为较新的汽车升级，并具有更先进的技术能力来获取，交换和处理信息，并将其引入与当今计算机硬件和软件行业的市场相似之处。虽然该概念远远超出了政府机构的当前政策理念，但调查系统非常简单：配备了机载计算和通信设备的参与车辆将能够确定车辆的当前位置以及过去的时空轨迹，因为它们穿越网络并与其他配备的车辆交换交易交易量。 配备的车辆在同一道路或交叉路口的相反方向移动将交换交通信息。 这项研究将使用基于分析概率和基于模拟的方法来回答问题，例如，在整个街道网络中生成和传播的有效信息，冲击波与信息波传播之间的关系是什么，以及在线路由算法的功能和算法要求之间的关系，以将所交换的数据转换为有意义的路由信息​​。 该分析将在各种经常性和非持续交通拥堵的情况下考虑装备和非装备驾驶员的好处。 如果以上分析表明了具有重大利益的潜力，我们打算与与西北大学有着紧密联系的主要沟通和汽车制造公司合作，以对系统的技术可行性进行初步评估，并可能部署飞行员。
