ASSIGN: Advisory System for SIGNallers for improved User Worked Crossing Resilience

泰利斯公司及其合作伙伴正在合作开发ASSIGN(信号员咨询系统)解决方案，以提高用户工作穿越(UWC)的弹性。Network Rail的东南线路董事总经理约翰·哈尔索尔表示：“平交道口仍然是铁路网上最大的风险来源。”目前，英国每年约有5人在平交路口遇难，据报道有数百起险些发生的事故。其中，配备电话的1700辆UWC分别造成12.5%和19%的行人和车辆相关死亡[ORR2016--健康和安全风险监管战略-4：平交路口]。在这些交叉路口，信号员有责任确定用户通过是否安全；由于UWC位于较长的闭塞区段，信号员通常不得不在不知道列车当前相对于UWC的位置的情况下做出这一决定。缺乏准确的列车定位往往意味着信号员不得不拒绝允许通过，这增加了面临长时间等待的人的冒险行为。Assign将新的稳健定位技术与现有的基于铁路云的系统相结合，创建了第一个新的应用程序，向信号员提供列车到达UWCs的时间信息。该系统旨在允许信号员快速验证他们做出的决定，从而为他们控制的基础设施提供更大的弹性。ASSIGN系统将被安装来监控巴恩斯泰普支线沿线的列车移动，该支线在20英里的路段中有超过25个UWC，ORR特别将其确定为Network Rail的一个关键挑战，他们必须解决这一挑战，以提高安全性和运营。信号员将试验并帮助改进Assign用户界面，这次试验的证据将被用来通知Assign在英国的推广。

Thales and their partners are collaborating to develop the ASSIGN (Advisory System for SIGNallers) solution for improved User Worked Crossing (UWC) Resilience. John Halsall, South East route managing director at Network Rail has stated: “Level crossings remain the biggest source of risk on the rail network.” Currently around five people a year are killed at level crossings in Britain with hundreds of reported near misses. Of these, the 1700 UWC equipped with telephones contribute to 12.5% and 19% of pedestrian and vehicular related fatalities respectively [ORR2016-Strategy for regulation of health and safety risks - 4: Level crossings]. At these crossings, it is the responsibility of the signaller to determine if it is safe for the user to cross; with UWC in long block sections, the signallers often have to make this decision without knowing the current position of a train in relation to a UWC. The lack of exact train positioning often means that to the signaller has to deny permission to cross, and this increases risk taking behaviours by people faced with long waits. ASSIGN brings together novel robust positioning technology with existing rail cloud-based system to create a new first of a kind application to provide train time of arrival information at UWCs to signallers. This system aims to allow signallers to quickly validate the decisions that they make and thus giving greater resilience to the infrastructure they control. The ASSIGN system will be installed to monitor train movement along the Barnstaple Branch Line, which has over 25 UWCs in a 20-mile section and is specifically identified by the ORR as a key challenge to Network Rail that they must address to improve safety and operations. Signallers will be trialling and helping refine the ASSIGN user interface, and evidence from this trial will be used to inform ASSIGN roll-out across the UK.
