In this paper, an improved approach to the network count location problem (NCLP) is introduced that allows the formulation of a linear programming problem to optimise locations of detectors. The general formulation also accounts for a second-best solution if existing detectors in the network are taken into account. Furthermore, the application of OD-specific weights enables the user to obtain information-maximising count locations as opposed to maximum OD coverage. These weights are calculated based on principal concepts of information theory. The approach has been implemented in a computer program that includes both options (second-best NCLP and weights). In addition, the user needs to specify the budget, i.e. the number of detectors to be placed.
