| Summary: | Green transportation has become a key research focus in recent years. As the evaluation of non-recurrent event is still in the infancy stage, the practicality of using existing pheromone-based system for green transportation is still an open question. To fill this gap, the impacts of non-recurrent events are assessed, when using the proposed Pheromone-based Green Transportation System (PGTS) under some practical scenarios such as accidental situation, heavy rain and their combination. First, accidental situation is evaluated by halting a vehicle on a target road with maximum allowable speed of 10 km/h. Second, heavy rain is modelled by reducing the maximum speed of the affected area by 20 km/h. Third, the performance of PGTS is also gauged based on the impacts from accidental situation and heavy rain. Based on Singapore traffic data, experimental results show that the proposed PGTS achieves competitive performance against all non-recurrent events.
