The Effect of Traffic Flow and Vehicle Speeds as a Determinant of Road Risk

战略道路对英国的经济成功至关重要，当这个网络受到交通堵塞和碰撞的影响时，经济就会受到影响。尽管英国战略道路上的车辆速度每分钟都有数据，但对交通流量和车辆速度变化所产生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。建立一个风险简介，可用于影响可变速度限制的设置、车辆速度的执行、通过高架门架向驾驶员发送信息以及更广泛的驾驶员教育方案。风险和伤亡的减少沿着流动的改善可能具有显著的经济效益

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
