Transportation infrastructures have recently gained increasing attention in the context of homeland security. Being both a main target for attacks and a method for carrying out such attacks, much effort is being allocated these days toward increasing our understanding regarding transportation networks. Specifically, measuring and predicting human mobility patterns along the links of a transportation network has been of a great importance to researchers in the field, as it contains the basic information needed in order to cope with transportation‐related threats more efficiently. Such threats can take, for example, the form of a group of terrorists trying to reach their target by car or a truck filled with chemical or radioactive material. These threats require homeland security agencies to rapidly deploy monitoring or surveillance units in key junctions, dispatch air units to central locations, etc. Clearly, carrying out this mission …
