Dynamic route planning system for road vehicle with data storage facility has record of street junctions and edges and records journey speeds and times

摘要

Time profiles for different journeys may be plotted on a graph and may be corrected to give time factors or vectors (Stutzwert-Factoren). Two curves may be plotted with a nearly coincident (F1,F2). Maxima (max (D)) may be recorded. First and second normalization factors may be used. The system has a CPU connected to a data bank and a traffic information module. The system also includes an input module, a display and a RAM, also a clock and a GPS and a GSM module.
