Abstract:Transportation is a crucial component of every society. However, today's transportation systems are facing significant challenges. In terms of safety, traffic accidents are the most common cause of death in the 15 to 34 age group by a wide margin. In terms of congestion, in the past three decades, average delay has tripled. Today, congestion wastes about 40 percent of travel time on average, unnecessarily consumes about 2.3 billion gallons of fuel annually, and adversely affects the envioronment. These critical issues of transportation are not only collecting a high toll on the economy, they are also changing the way that people live, travel, and work. Many countries are planning the wide deployment of vehicular ad hoc networks (VANETs) that can dramatically improve safety and efficiency of transportation systems. VANET is emerging as an exciting research field. Nevertheless, there is currently no rigorous mathematical framework for vehicular ad hoc networks. This research aims to develop a solid theoretical framework for wireless-enabled transportation networks by combining communication theory and traffic flow theory. This research aims to develop a new theory based on two separately established fields: Communications and Information Theory and Traffic Flow Theory. The research combines tools from Differential Geometry, Topology, Probability Theory, and Graph theory to provide a holistic theoretical analysis of wireless-enabled wireless communication systems. While this research increases the understanding in communication and traffic flow theory, it addresses important industrial needs. Although, the research is motivated by the important application of vehicular ad hoc networks, it turns out the developed theory is applicable to much broader scenarios, namely to the communication scenarios that are limited by geometry, line-of-sight, or restricted mobility pattern.Level of effort statement:At the recommended level of support, the PI will make every attempt to meet the original scope and level of effort of the project. Considering that the revised budget is very close to the original requested budget, the PI expects that this will be done with no problem.

摘要：交通运输是每个社会的重要组成部分。然而，当今的交通系统正面临着重大挑战。在安全方面，交通事故是15岁至34岁年龄段最常见的死亡原因，大幅领先。就拥堵而言，在过去三十年中，平均延误时间增加了两倍。如今，拥堵平均浪费了约 40% 的出行时间，每年不必要地消耗约 23 亿加仑的燃料，并对环境产生不利影响。这些关键的交通问题不仅对经济造成沉重打击，而且还改变了人们的生活、旅行和工作方式。许多国家正在计划广泛部署车载自组织网络 (VANET)，以显着提高交通系统的安全性和效率。 VANET 正在成为一个令人兴奋的研究领域。然而，目前车辆自组织网络还没有严格的数学框架。本研究旨在通过结合通信理论和交通流理论，为无线交通网络开发坚实的理论框架。 本研究旨在基于两个独立领域：通信与信息理论和交通流理论，开发一种新理论。该研究结合了微分几何、拓扑、概率论和图论等工具，为无线无线通信系统提供了全面的理论分析。虽然这项研究增加了对通信和交通流理论的理解，但它满足了重要的工业需求。尽管这项研究的动机是车载自组织网络的重要应用，但事实证明，所开发的理论适用于更广泛的场景，即受几何、视线或受限移动模式限制的通信场景。 努力程度声明：在建议的支持水平下，PI 将尽一切努力满足项目的原始范围和努力水平。考虑到修订后的预算非常接近最初要求的预算，PI 预计这将毫无问题地完成。
