- Abstract
When there is an anomaly of the motorway traffic with drastic reduction of capacity, the almost immediate establishment of a queue is frequent. The note shows a generalized methodology to estimate the time needed to travel along a route in which an incident has occurred (even partial) forming a queue and with several possible time evolutions to free the section. The method is applicable to real situations in a motorway infrastructure with the primary purpose of providing correct information to users by means of variable message panels placed in a section upstream of the incident. The methodology was developed under a research agreement stipulated between the company Autostrade per l'Italia SpA and the Department of Civil and Environmental Engineering at the University of Florence.
