Development of scenes drawing system for urban road accidents

摘要

Traffic scenes drawing system was developed utilizing a new method with MATLAB tools. According to development requirement, scene classes and subclasses were precisely analyzed and classified. Base on the resolving of basic and detail items on class layer or subclass layer, attribute parameters of all items were defined. After foundation of MATLAB environments and objects structure hierarchy, objects creation functions for subclass items and low layer items were developed. By GUI tools, accident scenes drawing system was developed. It also gave an applying example at last. It indicates that the development method is applicable and simple, also less developing workload and open expansion. The system not only is useful to quick dispose accidents, but also may provide digital scene information for accident reconstruction.
