    • "One approach to symbolization is to define symbols with readily available physical quantities and construct quantization criteria artificially. Qualitative Trajectory Calculus (QTC) is one type of such methods introduced in [15], where a one-dimensional (1-D) qualitative model was constructed, using three-scale (+, 0, -) quantization of the absolute and relative velocities of two objects. Another approach is Feature Vector Clustering (FVC) proposed in [16], where K-mean clustering was introduced to map the relationship between two vehicles into twelve symbols. "

    ABSTRACT: In most present frontal collision warning systems (FCWS), the warning algorithm mainly depends on simple combination of linearly predicted vehicle-motion parameters. Such systems suffer from high false-alarm-rate due to the incapability of identifying different transportation scenarios. Scenario parsing deals with such problems by analyzing transportation scenarios and applying specific threat assessment algorithm to each scenario. In this paper, approaches of symbolization and pattern/rule data mining are presented. Real-data experiments demonstrate that the approaches are effective

    ABSTRACT: Research has been done in generating, indexing, modelling and querying network-based moving objects. However, little work has been done in building a calculus of relations between these objects. In Van de Weghe et al. (2004b) an empirical approach based on an illustrative example is worked out in order to be able to represent and reason about the relative trajectories of pairs of objects moving along a road network. The approach has been called the Qualitative Trajectory Calculus along a road Network (QTC-N). This paper gives a more theorectical and analytical view on this calculus.
