“…Data collected in Washington State in 1994 and 1995 showed that the first phase took an average of about 12 min [11]. Meanwhile, a study using data from the Utah Department of Transportation concluded that every minute of delay in response time added an average of $925 to excess user costs and 93 more affected vehicles in 2018 [15]. The actual numbers must differ between jurisdictions, but early and accurate detection will certainly reduce the time spent on verification and contribute to the reduction of incident duration.…”

Non-recurrent congestion disrupts normal traffic operations and lowers travel time (TT) reliability, which leads to many negative consequences such as difficulties in trip planning, missed appointments, loss in productivity, and driver frustration. Traffic incidents are one of the six causes of non-recurrent congestion. Early and accurate detection helps reduce incident duration, but it remains a challenge due to the limitation of current sensor technologies. In this paper, we employ a recurrence-based technique, the Quadrant Scan, to analyse time series traffic volume data for incident detection. The data is recorded by multiple sensors along a section of urban highway. The results show that the proposed method can detect incidents better by integrating data from the multiple sensors in each direction, compared to using them individually. It can also distinguish non-recurrent traffic congestion caused by incidents from recurrent congestion. The results show that the Quadrant Scan is a promising algorithm for real-time traffic incident detection with a short delay. It could also be extended to other non-recurrent congestion types.
