A resilient transport network can effectively lessen the negative impact of disruptions such as man-made accidents or natural disasters and rapidly restore normal operation. New evolutions of Intelligent Transportation Systems (ITS) bring new solutions to enhance transportation resilience, but their specific effectiveness remains unclear. Vehicular ad-hoc networks (VANETs) are one of the most popular ITS technologies currently, promoting the inner connection of various entities in transport networks. This paper takes VANETs as an example to explore the positive effects of ITS technologies on the enhancement of transportation resilience through the simulation of Vehicles in Network Simulation (Veins) framework based on the data of Dublin city centre. The results show that, compared with scenario B, the road network equipped with VANET technology in scenario A has a 30.24% reduction in resilience loss after the traffic accident and a 25.94% increase in the speed of restoring its basic performance, thus relatively enhancing the resilience of the entire road network.
