Trajectory regression model for indoor pedestrian flow analysis on billboard evaluation

Over the last few years new measurement technology has revolutionized the performance measurement in outdoor advertising. A handful of pioneer countries trace personal mobility now via GPS devices, which allows for precise performance results of arbitrarily positioned outdoor poster campaigns. However, GPS technology has the drawback that it cannot be applied indoors due to signal loss. In Switzerland and Germany many valuable posters are situated in public buildings such as train stations or shopping malls and their evaluation is of high interest. In this paper we therefore present a new approach for the evaluation of mixed indoor-outdoor campaigns. Our approach consists of a pedestrian movement model denoting quantities and trajectories of the people in restricted spaces. The model is su pported by empirical traffic observations and can be integrated into standard trajectory evaluation. Our approach has been implemented for 27 major train stations in Switzerland.
