A real-time traffic signal system for safe and efficient intersections

澳大利亚每年的道路交通事故造成1200人死亡，36,500人受伤。信号交叉口是交通网络中的高风险节点，但目前的信号设计只考虑效率而不考虑安全。该项目旨在释放人工智能(AI)的力量，并与先进的极值模型相结合，以主动、高效地实时检测碰撞风险。其创新之处在于开发了一种新的交通信号控制系统，平衡了信号控制交叉口的安全性和效率。拟议的实时交通信号系统将从根本上改变十字路口的运营，并减少道路伤亡和排放。

Road traffic crashes result in 1,200 fatalities and another 36,500 injuries on Australian roads each year. Signalised intersections represent a high-risk node in a transportation network, but the current signal designs only consider efficiency but not safety. This project aims to unleash the power of artificial intelligence (AI) and integrate with the advanced extreme value models for proactive and efficient detection of crash risk in real-time. Its innovations lie on developing a novel traffic signal control system balancing safety and efficiency of signalised intersections. The proposed real-time traffic signal system will fundamentally transform the intersection operation and lead to reductions of road fatalities, injuries and emissions.
