十字路口是危险的地方。威胁来自行人、自行车和车辆之间的相互作用、在没有车道标记的情况下更复杂的车辆轨迹、阻止确定谁有通行权的阶段、看不见的车辆接近、车辆障碍物和非法移动。这些挑战不会被Vision Zero计划中规定的“道路饮食”和道路重新设计完全解决，也不会被拥有许多传感器和不知疲倦地关注周围环境的自动驾驶车辆完全克服。事故也可能发生，因为司机、骑自行车的人和行人没有他们需要的信息来避免错误的决定。在这些情况下，丢失的信息可以通过智能交叉口进行计算和广播。这些信息给出了当前的全信号相位、相位改变的估计时间以及驾驶员或自动驾驶车辆盲点的占有率。基于对亚利桑那州坦佩一个十字路口自动Uber沃尔沃和手动本田CRV之间的事故的分析，本文开发了智能十字路口的设计，并最终提出了智能十字路口基础设施的建议。智能十字路口也是受保护十字路口设计的软件版本，旨在改善骑自行车的人和行人通过十字路口的通道。
Intersections are hazardous places. Threats arise from interactions among pedestrians, bicycles and vehicles, more complicated vehicle trajectories in the absence of lane markings, phases that prevent determining who has the right of way, invisible vehicle approaches, vehicle obstructions, and illegal movements. These challenges are not fully addressed by the "road diet" and road redesign prescribed in Vision Zero plans, nor will they be completely overcome by autonomous vehicles with their many sensors and tireless attention to surroundings. Accidents can also occur because drivers, cyclists and pedestrians do not have the information they need to avoid wrong decisions. In these cases, the missing information can be computed and broadcast by an intelligent intersection. The information gives the current full signal phase, an estimate of the time when the phase will change, and the occupancy of the blind spots of the driver or autonomous vehicle. The paper develops a design of the intelligent intersection, motivated by the analysis of an accident at an intersection in Tempe, AZ, between an automated Uber Volvo and a manual Honda CRV and culminates in a proposal for an intelligent intersection infrastructure. The intelligent intersection also serves as a software-enabled version of the 'protected intersection' design to improve the passage of cyclists and pedestrians through an intersection.
