Abstract

Literature proposes link-based indicators as predictors of the delay caused by a blockade on a particular link. This paper cross-compares these indicators and compares them with the result of a full simulation. The indicators predict different links to be vulnerable. Furthermore, the indicators do not provide a good indication of the delay of a blockade, partly because traffic dynamics (including spillback or blocking back) are not well included in the indicators. A linear combination of different indicators does not increase the performance either. Once more than one indicator is included in the fit, the predictive value of the combination of the indicators is lower than the predictive value of one indicator due to over fitting.
