摘要
Recent studies have shown that aggregated over a whole network a rather crisp relation between average density (accumulation) and average flow (production) exists. This relationship is called the Network Fundamental Diagram (NFD). We developed a tool to automatically design networks. Using this tool, different networks are created for which the following general properties are the same: (1) the number of intersections, (2) length of signalised multi-lane arterial roads, (3) length of single-lane urban roads. The main contribution of this paper is that it shows that NFDs are not only dependent on these properties, but also on the exact network layout (e.g., which link connects to which link) and/or origin-destination pattern. As a consequence, the NFD needs to be determined for each network separately and cannot be derived from these general properties.
