H Mongeot, JB Lesort
Transportation research record, 2000•journals.sagepub.comThe impact of immobile traffic incidents on traffic flow dynamics is modeled using first-order
macroscopic flow theory, in which an incident is characterized by dual severity, possibly
extensive length, and duration. Incident-induced flow perturbation variations through space
and time are then developed as are associated analytical expressions of shock waves,
perturbation clearing time, and maximum queue length.
