Emergency services (Ambulance Service; Fire & Rescue Service) play a crucial role during flood response, as they participate in joint command-control structures and are central to rescue and relief efforts (Frost 2002). Emergency services are often legislated to meet defined response times. UK legislation requires that emergency responders comply with strict timeframes when reacting to incidents. Category 1 responders such as the Ambulance Service and the Fire & Rescue Service are required to reach 75% of 'Red 1' (high-priority, life-threatening incidents) in less than 8 and 10 minutes respectively from the time when the initial call was received. This includes blue-light incidents such as life-threatening and traumatic injury, cardiac arrest, road collisions, and individuals trapped by floodwaters. In 2015-16, only one England ambulance trust met the response time targets and 72.5% of the most serious (Red 1) calls were responded to within 8 minutes, against a legislative target of 75% (National Audit Office, 2017). Between 2007-2014, the highest percentage Scottish Ambulance Service achieved was 74.7% in 2013 (HEAT standard).Rising demand combined with inefficient call handling and dispatch systems are often cited as the reasons for missing the above targets. However, response times can also be affected by flood episodes which may limit the ability of emergency responders to navigate through a disrupted road network (as was the case during the widespread UK flooding in 2007). The impact of flooding on road networks is well known and is expected to get worse in a changing climate with more intense rainfall. For example, in Portland, USA under one climate change scenario, road closures due to flooding could increase time spent travelling by 10% (Chang et al. 2010). The impact of an increased number of flooding episodes, due to climate change, on road networks has also been modelled by for the Boston Metropolitan area, USA (Suarez et al., 2005). This study found that between 2000 and 2100 delays and trip-time losses could increase by 80% and 82% respectively. The Pitt Review (2008) suggested that some collaborative decision making during the 2007 event was hampered by insufficient preparation and a lack of information, and better planning and higher levels of protection for critical infrastructure are needed to avoid the loss of essential services such as water and power. More recently, the National Flood Resilience Review (HMG, 2016) exposes the extent to which a significant proportion of critical assets are still vulnerable to flooding in England and Wales. In particular, it highlights that the loss of infrastructure services can have significant impacts on people's health and wellbeing.This project will combine: (i) an established accessibility mapping approach; (ii) existing national flood datasets; and (iii) a locally tested, recent-expanded real-time flood nowcasting/forecasting system to generate accessibility mapping, vulnerability assessment and adaptation evaluation for various flood conditions and at both the national and city-region scale. The project will be delivered via three sequential Work Packages, including:(a) Mapping emergency service accessibility according to legislative timeframes;(b) Assessing the vulnerability of populations (care homes, hospices and schools); and (c) Evaluating adaptation strategies (e.g. positioning standby vehicles).

紧急服务（救护车服务;消防和救援服务）在洪水响应中发挥着至关重要的作用，因为它们参与联合指挥控制结构，是救援和救灾工作的核心（弗罗斯特2002年）。紧急服务往往是法定的，以满足规定的响应时间。联合王国立法要求应急人员在对事件作出反应时遵守严格的时间表。救护车服务和消防救援服务等第1类响应人员必须分别在收到初始呼叫后的8分钟和10分钟内达到“红色1”（高优先级、危及生命的事件）的75%。这包括蓝光事件，如危及生命和创伤性伤害，心脏骤停，道路碰撞以及被洪水围困的个人。在2015-16年度，只有一个英格兰救护车信托基金达到了响应时间目标，72.5%的最严重（红色1）呼叫在8分钟内得到响应，而立法目标为75%（国家审计署，2017）。在2007-2014年期间，苏格兰救护车服务在2013年达到的最高百分比为74.7%（HEAT标准）。不断增长的需求加上低效的呼叫处理和调度系统经常被认为是错过上述目标的原因。然而，响应时间也可能受到洪水事件的影响，这可能会限制应急响应人员在中断的道路网络中导航的能力（如2007年英国大范围洪水期间的情况）。洪水对公路网的影响是众所周知的，预计在气候变化和降雨量增加的情况下会变得更糟。例如，在美国波特兰，在一种气候变化情景下，洪水导致的道路封闭可能会使旅行时间增加10%（Chang等人，2010年）。由于气候变化，洪水事件数量增加对道路网络的影响也由美国波士顿大都市区建模（苏亚雷斯等人，2005年）。这项研究发现，在2000年至2100年之间，延误和旅行时间损失可能分别增加80%和82%。《皮特评论》（2008年）表明，2007年活动期间的一些协作决策因准备不足和缺乏信息而受到阻碍，需要对关键基础设施进行更好的规划和更高水平的保护，以避免失去水和电力等基本服务。最近，国家洪水恢复力评估（HMG，2016）揭示了英格兰和威尔士相当大一部分关键资产仍然容易受到洪水影响的程度。该项目将联合收割机：（一）既定的无障碍制图方法;（二）现有的国家洪水数据集;（三）现有的国家洪水数据集;（四）现有的国家洪水数据集;（五）现有的国家洪水数据集;（六）现有的国家洪水数据集;（七）现有的国家洪水数据集;（八）现有的国家洪水数据集;（九）现有的国家洪水数据集;（十）现有的以及（iii）一个经过当地测试、最近扩大的实时洪水临近预报/预报系统，以生成可达性地图，在国家和城市区域范围内，对各种洪水条件进行脆弱性评估和适应性评估。该项目将通过三个连续的工作包交付，包括：（a）根据立法时间框架绘制紧急服务可获得性图;（B）评估人口脆弱性（护理院、收容所和学校）;（c）评估适应战略（例如部署备用车辆）。
