Emme Desktop

Emme Desktop provides mapping, editing, data management and scenario comparison capabilities for Emme models. It helps planners make informed planning decisions using rich maps and reports and transparent access to model data. Emme Desktop provides:

  • A wide range of dynamic maps, charts, and reports that automatically update as models run or scenarios are compared.
  • An extensible mapping and charting framework that produces great looking visualizations and gives modellers complete transparency on their data.
  • An active scenario system for live scenario comparisons, and synchronization with Emme Modeller for modelling and results visualization.
  • Point-and-click network editing tools with undo/redo support and session recording.
  • Relational and spatial data management, mapping and processing and included streaming basemaps from popular services
  • Drag-and-drop automation via the Emme Notebook and scripting via the Emme Desktop Python API

Maps, charts and reports

Reproducible reporting

Emme Desktop includes a unique mapping framework with an exhaustive and extensible set of transport-themed maps and charts for visualization, analysis and reporting.

A comprehensive library of 100+ maps and charts (worksheets) covering the entire transport planning domain make it easy to get started. Included are charts like network scatterplots and histograms (for nodes, links, turns, transit lines, transit segments), matrix scatterplots and efficient matrix histograms, network maps for topological display of supply- and demand-side information, conditionally formatted reports and tables, and a variety of special-purpose analyses like grid values for emissions, isochrones / shortest-path displays, and many more.

Build your own. Users can build entirely new maps and charts using dozens of mapping layers. These layers include drawing components for base networks, turns, transit services, network text, shapes, symbols, bars, desire lines, GIS Basemap data, shapefiles, legends and more. Or open a worksheet from the standard library and modify or add to it to keep it relevant for local use.

Transparency. Emme Desktop works on the same Emme Database used for modelling, so there is nothing to get between the analyst, planner or modeller and the model data. Transit services, delay functions, attribute values, network topologies, access connectors, etc. are always plain to see and clear to interpret.

Model dashboards. Maps, charts and tables can be dragged to the Emme Notebook to easily create stunning model dashboards that sit inline and update together with model workflows. Share literate, reproducible model dashboards with colleagues and in presentations.

Network editing and data management

The network editor provides easy point-and-click editing of Emme network data. It supports consistent, multi-modal editing of nodes, links, turns, transit lines, transit segments, link shape, and associated attributes. Editing sessions keep a full undo/redo stack of operations. And the network calculator permits precise expression-based modification of network and demand data from within Emme Desktop.

Scenario management features help to keep networks manageable. Apply changes from one scenario to others to keep them in sync. Apply full or partial modifications to permit the use of 'reference' or 'master' scenarios. Use pervasive network comparison to compare anything; network topology, values, charts, even tabular summaries.

Data tables. Now you can work with spatial and relational data right within Emme Desktop. Use standard relational and spatial operations like join, summarize, spatial join, buffer, re-project or write your own SQL queries. Map spatial data, transfer results for use in model workflows, or export results to spreadsheets or other applications.

The Emme Database guarantees consistency between multimodal network data assets in one place so you don't have to dig through hundreds of files littered to find out what's in your model. With Emme 4.2, the Emme Database supports thousands of extra attributes, up to 60 modes and 240 classes in traffic assignments, up to 40,000 matrices and longer attribute and matrix names.

Transit Compare

Scenario comparisons and expressions

Scenario comparisons and scenario displays are central to Emme Desktop. All expressions, maps, charts and reports are made to work against one or more scenarios that the analyst can arrange on-the-fly.

Active scenarios in the Project Explorer are immediately displayed in open worksheets. As soon as scenarios are opened, closed or re-ordered, maps, charts and reports automatically adjust to display new information. Since worksheets update dynamically from active scenarios it is easy to quickly inspect new or updated model results. Also, maps, charts and reports need be created only once, not every time results change. Certain categories of worksheets are available out-of-the-box for scenario comparison purposes, which update when more than one scenario is activated at the same time. Performing alternate comparisons is as simple as dragging to activate different scenario pairs.

Scenario comparisons can be used anywhere because they are built right into expressions. For example, use the network calculator to quickly compare or compute values between scenarios, use filter expressions to identify network elements that fall within a certain epsilon difference between scenarios, or display symbol size, color or other formatting according to scenario differences. Whether comparisons are used in expressions or not, accessing scenario data and data across scenarios is easy and always in-sync with active scenarios.

Great basemaps from online map services including ArcGIS Online and OpenStreetMap add context to any map in a responsive layer that provides quick view navigation and asynchronous download of tiles. Choose from world imagery, world street, topographic, transportation or OpenStreetMap layers. Or map local data from a variety of popular spatial vector formats.

The ArcGIS Basemap Add-on provides access to a variety of native ArcGIS data, including ArcMap documents and layers, geodatabases and a long list of raster datasets, exactly as they would appear in ArcMap, as well as ArcGIS Online streaming map services.
