路边碰撞是所有国家都面临的重大问题。城市化导致交通拥堵和路边车辆相撞事件增加。根据英国政府交通部的数据，大多数车辆相撞发生在城市道路上，经验证据表明，司机更有可能在城市环境中违反当地和固定的速度限制。英国交通部进行的分析发现，英国的事故预防措施每年的成本估计为330亿英镑。因此，有强烈的动机调查城市环境中路边碰撞的原因，以更好地准备交通管理，支持地方议会的政策，并最终降低撞车率。这项研究利用基于智能体的建模作为一种工具来计划、实验和调查超速和车辆密度与碰撞之间的关系。研究发现，无论司机在多大程度上遵守限速规定，较高的交通密度都会导致更多车辆以较慢的速度行驶。其次，对于所有密度，碰撞随着速度顺应性的降低而线性增加。当所有车辆都符合所有密度的速度限制时，碰撞发生率最低。最后，更高的全球流量密度会导致更高的本地流量密度--所有遵守级别的接近碰撞的站点，从而增加这些站点周围拥堵的可能性。当这项工作扩展到使用经验数据的真实世界应用时，可以支持有效的道路安全政策。
Roadside collisions are a significant problem faced by all countries. Urbanisation has led to an increase in traffic congestion and roadside vehicle collisions. According to the UK Government's Department for Transport, most vehicle collisions occur on urban roads, with empirical evidence showing drivers are more likely to break local and fixed speed limits in urban environments. Analysis conducted by the Department for Transport found that the UK's accident prevention measure's cost is estimated to be 33bn pound per year. Therefore, there is a strong motivation to investigate the causes of roadside collisions in urban environments to better prepare traffic management, support local council policies, and ultimately reduce collision rates. This study utilises agent-based modelling as a tool to plan, experiment and investigate the relationship between speeding and vehicle density with collisions. The study found that higher traffic density results in more vehicles travelling at a slower speed, regardless of the degree to which drivers comply with speed restrictions. Secondly, collisions increase linearly as speed compliance is reduced for all densities. Collisions are lowest when all vehicles comply with speed limits for all densities. Lastly, higher global traffic densities result in higher local traffic densities near-collision sites across all adherence levels, increasing the likelihood of congestion around these sites. This work, when extended to real-world applications using empirical data, can support effective road safety policies.
