Abstract With the technological drive for realizing smart cities, work on Autonomous Intersection Management (AIM) protocols opts to replace the traditional traffic light system by using cooperative Vehicle-to-Vehicle (V2V) communication in order to decrease road congestion and increase vehicular throughput. However, these protocols simply ignore pedestrians as road users and do not provision for safe pedestrian crossing. Basically, a road intersection not only could be traffic bottleneck, but also nearly 23% of the total automotive related fatalities and almost 1 million injury-causing crashes occur at or within intersections every year. This article opts to fill such a technical gap. We present a novel system that prioritizes pedestrians crossing and guarantees safety while preserving the efficiency of AIM based approaches. Our system does not require additional infrastructure or pedestrian-carried devices, and works for both self-driving and human-derived vehicles. The simulation results show that our proposed system for Autonomous Pedestrian Crossing (APC) protocol of non-signalized intersections significantly decreases the vehicle’s delay and pedestrian walk duration compared to the conventional traffic light-based systems. The effectiveness of APC is validated for traffic scenarios with (1) self-driving vehicles, and (2) mix of human-based and self-driving vehicles.

智能城市中人行横道和增加车辆流量的协议

摘要 随着实现智慧城市的技术驱动,自主路口管理(AIM)协议的工作选择通过使用协同车对车(V2V)通信来取代传统的交通灯系统,以减少道路拥堵并增加车辆吞吐量。然而,这些协议只是忽略作为道路使用者的行人,并没有提供安全的行人过路。基本上,道路交叉口不仅可能成为交通瓶颈,而且每年有近 23% 的汽车相关死亡事故和近 100 万起伤害事故发生在交叉口处或交叉口内。本文选择填补这样的技术空白。我们提出了一种新颖的系统,该系统优先考虑行人过马路并保证安全,同时保持基于 AIM 的方法的效率。我们的系统不需要额外的基础设施或行人携带的设备,并且适用于自动驾驶和人类衍生的车辆。仿真结果表明,与传统的基于交通灯的系统相比,我们提出的无信号交叉口自动人行横道 (APC) 协议系统显着减少了车辆的延迟和行人步行持续时间。APC 的有效性在以下交通场景中得到验证:(1) 自动驾驶车辆,以及 (2) 人工驾驶和自动驾驶车辆的混合。仿真结果表明,与传统的基于交通灯的系统相比,我们提出的无信号交叉口自动人行横道 (APC) 协议系统显着减少了车辆的延迟和行人步行持续时间。APC 的有效性在以下交通场景中得到验证:(1) 自动驾驶车辆,以及 (2) 人工驾驶和自动驾驶车辆的混合。仿真结果表明,与传统的基于交通灯的系统相比,我们提出的无信号交叉口自动人行横道 (APC) 协议系统显着减少了车辆的延迟和行人步行持续时间。APC 的有效性在以下交通场景中得到验证:(1) 自动驾驶车辆,以及 (2) 人工驾驶和自动驾驶车辆的混合。
