Evaluation of a Dynamic Map Architecture with ATAM

Abstract

Dynamic Map can be considered a complex information system, composed of spatial databases, storing  static and dynamic data relevant for urban traffic, as well as a set of software modules responsible for data collection, interpretation and provision. The data originates from a network of sensors, both fixed (e.g. video detectors, acoustic sensors, inductive loops) and on-board GPS receivers installed in vehicles. Clients of the Dynamic Map are various software modules  performing such tasks as visualization, route planning, traffic optimization, object tracking and threat detection.  The paper discusses experiences with  an evaluation of the system architecture using the ATAM (Architectural Tradeoffs Analysis Method).  The stages of evaluation comprise describing architectural views, identification of key scenarios and evaluation of risks of their realization.
