Quantifying Incident-Induced Travel Delays on Freeways Using Traffic Sensor Data: Phase II, Research Note

摘要

To improve understanding of incidents and manage them more effectively, WSDOT launched this research project to develop a practical method for quantifying freeway Incident-Induced Delay (IID) using traffic sensor data. IID refers to the extra travel time, in addition to the travel time of an incident-free scenario, which all incident-impacted drivers take to complete a certain length of trip. Quantifying IID for an incident requires knowing both the total delay under the incident scenario and the recurrent delay under the incident-free scenario. The difference between total delay and recurrent delay is the delay induced by the incident.
