Recent years have seen a series of increasingly detailed simulation models developed to aid in the design of new road infrastructure. In general, these models usually assume that all drivers follow the rules of the road unless forced to do otherwise. It has become apparent however that this means such models miss a form of driving behaviour known as cooperative priority, where drivers for example choose to allow another vehicle/pedestrian to move first when the rules say they would have to wait, to change lane to allow another vehicle to merge from a side road when the rules do not recommend this, or to leave a gap in a stationary queue of traffic simply for the benefit of others. Without correct representation of such behaviour in the transport models, it is likely that queues and delays at junctions are being significantly overestimated, leading to incorrect data being used in benefit-cost analyses and potentially poor decisions over the implementation of junction improvement schemes. This project will therefore investigate the prevalence of such cooperative behaviour and develop ways in which to incorporate it into existing modelling frameworks.

近年来，一系列越来越详细的仿真模型被开发出来，以帮助设计新的道路基础设施。一般来说，这些模型通常假设所有驾驶员都遵守道路规则，除非被迫这样做。然而，很明显，这意味着此类模型错过了一种被称为合作优先权的驾驶行为，例如，当规则规定他们必须等待时，驾驶员选择允许另一辆车/行人先行；当规则不建议时改变车道以允许另一辆车从旁路并入；或者只是为了其他人的利益而在静止的交通队列中留下间隙。如果没有在交通模型中正确表示此类行为，路口的排队和延误可能会被严重高估，从而导致在效益成本分析中使用不正确的数据，并可能在实施路口改进计划时做出错误的决策。因此，该项目将调查这种合作行为的普遍性，并开发将其纳入现有建模框架的方法。
