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

泰雷兹及其合作伙伴正在合作开发分配（信号咨询系统）解决方案，以提高用户工作交叉（UWC）的弹性。英国铁路网东南线总经理约翰•霍尔萨尔表示：“平交道口仍然是铁路网最大的风险来源。”目前，英国每年大约有5人在平交道口死亡，据报道有数百人险些丧命。其中，配备电话的1700个UWC分别占行人和车辆相关死亡人数的12.5%和19% [orr2016 -健康和安全风险监管策略- 4：平交道口]。在这些交叉路口，信号员有责任决定使用者过马路是否安全；由于UWC位于较长的路段，信号员通常不得不在不知道列车相对于UWC的当前位置的情况下做出这个决定。缺乏准确的列车定位通常意味着信号员不得不拒绝允许过桥，这增加了人们面对长时间等待的冒险行为。ASSIGN将新颖强大的定位技术与现有的铁路云系统结合在一起，创建了一个全新的应用程序，为uwc的信号员提供列车到达时间信息。该系统旨在使信号员能够快速验证他们所做的决定，从而为他们控制的基础设施提供更大的弹性。ASSIGN系统将安装在Barnstaple支线上，用于监控列车运行，该支线在20英里的路段上有超过25个UWCs， ORR特别将其确定为网络铁路必须解决的关键挑战，以提高安全性和运营。Signallers将进行试验，并帮助改进ASSIGN用户界面，这次试验的证据将用于通知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.
