Strategic roads are vital to the economic success of Britain and the economy suffers when this network is compromised by traffic jams and collisions. Despite the availability of minute-by-minute data for vehicle speeds on the UK's strategic roads, there has been little analysis of the associated risks arising from changes in traffic flow and vehicle speeds. This project would aim to analyse this data and aggregate it with a wider array of related datasets (collisions, precipitation, light conditions, temperature etc.) to create a risk profile that could be used to influence setting of variable speed limits, enforcement of vehicle speeds, driver messaging through overhead gantries and wider programmes of driver education. The reduction in risk and casualties along with improvements in flow could have a significant economic benefit

战略道路对英国的经济成功至关重要，当交通堵塞和碰撞损害了这一网络时，经济就会受到影响。尽管有英国主要道路上每分钟的车速数据，但对交通流量和车速变化所带来的相关风险的分析却很少。该项目旨在分析这些数据，并将其与更广泛的相关数据集（碰撞、降水、光照条件、温度等）进行汇总，以创建一个风险概况，可用于影响可变速度限制的设置、车辆速度的执行、通过架空门架发送驾驶员信息以及更广泛的驾驶员教育方案。降低风险和人员伤亡以及改善流量可以带来显著的经济效益
