Aurora Road Network Modeler Description
Aurora Road Network Modeler (RNM) is a handy set of tools specially designed for operational planning and management of travel corridors (road networks comprised of freeways and surrounding urban arterials) and analysis of their performance. It is based on the Aurora Object-Oriented Framework for Simulation and Analysis of Flow Networks and is implemented in Java. Simulator is a graphical application with interactive user interface that runs traffic simulations on road networks. Traffic flow and density are computed using the macroscopic Cell Transmission Model. It also computes such traffic characteristics as speed, VMT, VHT, delay and productivity loss and generates flow, density and speed contour plots making it convenient to compare with the real traffic data collected by systems such as PeMS. The user can create simulation scenarios by means of events that change user-specified configuration parameters of the road network at user-specified times. Configurator is a graphical application with interactive user interface whose purpose is to produce XML configuration files for the Simulator. It can be used to build road networks from scratch; edit existing road networks by deleting or reassigning network components or adding new network components; efficiently provision road parameters such as fundamental diagrams and split ratios; and input demand profiles. GIS Importer is a graphical application with interactive user interface that extracts road information from the GIS .shp and .dbf files and saves it in the XML format of Aurora configuration file. This configuration file can be refined in the Configurator and then used by the Simulator. It is recommended to use GIS Importer together with the open source OpenJUMP software used for geometric filtering of GIS data.
