Emme 4.3 introduces new scenario management features, improvements to multimodal network editing, a new Space-time Traffic Assignment for time-dependent network loading, multithreaded optimizations for transit analysis, a new Data Table API for automating work with spatial and relational data, support for text attributes on network elements, new and enhanced Emme Modeller tools, mapmatching capabilities, improved Emme Notebook workflows, GIS layer support in Network Find, a new look-and-feel and more.
New scenario management features allow saving network edit sessions as 'build' files which can be used to apply to child scenarios in master/slave arrangements, as transactional project alternatives or for collaboration with colleagues. It is then possible to 'stage' network builds with graphical previews of edit operations before they are applied, to 'build' the edits into a different scenario, and then to graphically summarize the applied edits.
A new traffic assignment for time-dependent network loading with the convenience of existing network topology and delay functions. Demand matrices may be time-profiled and the network loading varies over time as flow progresses through the network. This method is especially recommended for statewide, national or long-distance models in which longer trips should not simultaneously load all time periods at once.
All Extended transit analysis tools are now multithreaded. Transit strategies are also up to 50% smaller on disk. Expect the following performance improvements with between 8 and 16 threads, depending on application size. Also note that some procedures will continue to scale with more threads.
|Transit Analysis Type||Performance Gain|
|Matrix Results||3-6x faster|
|Strategy Analysis||3-7x faster|
|Path Analysis||6-12x faster|
|Station to Station Analysis||4-5x faster|
Transit lines are automatically 'shelved' and may be re-routed around network changes. Context-sensitive defaults for boardings/alightings and new merge node and attach/detach link operations help save time coding. Edit operations, undo/redo and map drawing are all faster, and map rendering is improved.
