Reducing Fatality Disruptions with 8K Forward Facing CCTV Optimised for Remote Access

正确的时间性能是铁路客户在铁路上有一个好的旅程的关键，而死亡是中断的主要来源。这些事件导致铁路关闭，同时英国交通警察（BTP）进行调查，铁路准备重新开放。国家网络铁路中断融合单元（NR）提取的信任数据显示，英国铁路平均每年约有350人死亡，造成79万分钟的延误，相当于每次事故延误2300分钟。项目合作伙伴火车运营公司Avanti West Coast表示，在自杀事件发生后，服务通常会相对较快地恢复，但在不明原因的死亡事件发生后，服务通常要到第二天才能恢复，这扰乱了客运和货运旅程，降低了客户对铁路的信心。列车发生事故后，驾驶员必须将事故报告给NR信号员，由后者通知BTP。BTP通过采访司机来确定这起事件是“疑似自杀”还是“无法解释”。如果司机没有清楚地看到受害者，或者受到精神创伤，无法提供可靠的陈述，那么，如果有的话，BTP可以查看火车上的事件前向视频。如果不能排除其他各方的参与，那么BTP必须声明事件原因不明，并且平均要求将现场视为犯罪现场，采取证人陈述并记录现场，这使解决事件所需的时间增加了1小时45分钟（70%）。因此，将死亡宣布为自杀可以取决于前视视频，但目前前视视频的全高清标准的局限性会导致质量问题。众所周知，除了明亮的灯光外，录像效果很差，而现实生活中的条件（平台上的阴影、阴天或黄昏）会使录像无法使用。为此，该项目将使用新兴的8K视频技术、云技术和先进的人工智能图像识别技术，为BTP提供可以快速进行法医分析的高质量视频。有了更好的记录，更多由于当前技术限制而被判断为无法解释的事件将被正确地视为自杀，减少了手工处理的时间，并减轻了更广泛的客户中断。我们的联盟由Rail Innovations领导，包括视频软件公司One Big Circle Ltd，萨里大学，Avanti West Coast和火车所有者Angel Trains Ltd .，将应用创新技术和新技术来实现8K前向视频的部署。

Right-Time performance is key to railway customers having a good journey on the railways and fatalities are a major source of disruption. These incidents cause lines to be closed whilst British Transport Police (BTP) investigate and the railway is readied to reopen. TRUST data extracted by the National Disruption Fusion Unit of Network Rail (NR) show that, on average, there have been approximately 350 fatalities pa on GB railways causing 790,000 Delay Minutes pa, equating to 2,300 Delay Minutes per incident.Project partner Train Operating Company Avanti West Coast states that, after a suicide, services typically recover relatively quickly, but after an Unexplained fatality, services typically do not recover until the next day, disrupting passenger and freight journeys and reducing customer confidence in the railways.After a train encounters a fatality, the driver must report the incident to the NR signaller who informs BTP. BTP establish whether the incident was a "Suspected Suicide" or was "Unexplained" by interviewing the driver. If the driver did not have clear sight of the victim or is traumatised and cannot provide a reliable statement, then, if available, BTP can review the Forward-Facing Video of the event from the train.If the involvement of other parties cannot be ruled out, then BTP have to declare the incident Unexplained and, on average the requirement to treat the site as a crime scene, take witness statements and record the scene adds 1h45m (70%) to the time taken to resolve the incident.Declaring a fatality as a suicide can therefore depend on the Forward-Facing Video, but the limitations of the current Full High Definition standard of Forward-Facing Video cause quality problems. Recordings are notoriously poor in anything other than bright lighting, and real-life conditions (dark shadows on platforms, an overcast day or twilight) render footage unusable.In response, this project will use emergent 8K video technology, Cloud technology and advanced Artificial Intelligence image recognition to provide BTP with high quality video they can forensically analyse quickly. With better recordings, more incidents that would be judged as Unexplained due to current technology limitations, will correctly be deemed as suicides, reducing hand-back time and alleviating wider customer disruption.Our consortium, led by Rail Innovations, and comprising video software company One Big Circle Ltd, University of Surrey, Avanti West Coast and train owner Angel Trains Ltd, will apply innovative technologies and novel techniques to enable the deployment of 8K Forward-Facing Video.
