The development of new technologies and transportation modes is a crucial component for improving urban mobility. For instance, researchers have shown that vehicular networks are a promising technology to monitor and reduce traffic jams. Nevertheless, most of these solutions rely on costly external infrastructures, such as roadside units or cellular networks. In this work, we propose DisTraC, a protocol for vehicular ad hoc networks. DisTraC is a traffic congestion control protocol of low communication overhead that aims to reduce the average travel time of vehicles by using vehicle-to-vehicle (V2V) communication. The protocol is independent of external infrastructures as uses only V2V communication. Simulation results show that DisTraC outperforms other solutions published in the literature both in terms of communication overhead and capability to reduce traffic congestion.

新技术和运输方式的发展是提高城市交通能力的重要组成部分。例如，研究人员表明，车载网络是监视和减少交通拥堵的有前途的技术。然而，这些解决方案中的大多数都依赖于昂贵的外部基础设施，例如路边单元或蜂窝网络。在这项工作中，我们提出了DisTraC，一种用于车辆自组织网络的协议。DisTraC是一种通信开销较低的交通拥塞控制协议，旨在通过使用车对车（V2V）通信来减少车辆的平均行驶时间。该协议仅使用V2V通信，因此与外部基础结构无关。
