| Summary: | The purpose of this article is to present the authors' own software for predicting changes in the density and directions of traffic flows and to compare overall results of research on transport accessibility with the results returned in the study of transport accessibility conducted with the software (isochronic accessibility). Developed for research purposes, the authors' application is based on Dijkstra's algorithm, which is classified as one of the greedy ones and does not always return optimum results, even though it is considered to be generally accurate. In the course of the research, it was stated that the implementation of Dijkstra's algorithm in the RoadLoad tool is suitable for studying and prognosing phenomena, under the assumption that there aredetailed data on the point of departure and destination for each trip. The tool enables us to research a spatial (cumulated values of network load) as well as time-spatial (network load at virtually any time) dimension of the phenomenon. It cannot be applied, however, withouttheknowledge of the transport behavior characteristics ofthe users of the road system. |
