Abstract: Reducing the response time of emergency vehicle(EV) is accompanied with many health and traffic-related benefits. New technologies can be utilised in creating a cooperative lane-changing behaviour for surrounding traffic to reduce the response time. In this research, the influence of lane-changing behaviour on the delay of EV and surrounding vehicles was studied in microscopic traffic simulation. A driving behaviour and a pre-emption algorithm were developed to prioritise EVs on a signalised corridor. Two areas in front of EV were defined including stopping and lane-changing areas with different behaviours in a connected and autonomous traffic environment. It was concluded that using stopping and lane-changing areas together is more favourable regarding the delays of both EV and surrounding traffic. Also, the results verified the presence of an optimum lane-changing threshold after which the EV delay became constant.
