Abstract
A method of estimating traffic jams on a roads network includes receiving information from at least one cellular PLMN covering a geographic region wherein at least one road of the roads network to be monitored is located. The information includes data related to call traffic handled by the cellular PLMN in an at least one area of the geographic region, and an indication related to a mobility of mobile terminals into/out of the area. The method may further include providing an indication of traffic jam in the at least one road in case the call traffic handled by the cellular PLMN in the at least one area exceeds a first threshold and the indication related to the mobility of mobile terminals into/out of the area trespasses a second threshold.
