Via 1.5

After a longer-than-usual development time, we’re happy to announce the availability of Via 1.5. Besides some improvements under the hood, the following major new features are available in the new version:

  • WebMap Layer: The Web Map Layers allows to display maps from internet services like OpenStreetMap, Bing or Google Maps as background for your visualization. (Part of the Map Background plugin)
  • Select Facility Analysis: Which links are taken by agents to travel to or from a facility? Find out with the new select facility analysis, similar to the select link analysis most transport planners will be familiar with.
  • Meta Data Manager: Export and import Views and Layer styles for maintaining a consistent look through multiple scenarios and visualizations.
  • Network Difference Layer: Visualize the difference of arbitrary link attributes, even dynamic ones like average link volumes and average link speeds.
  • Rotate Map: Does your region not match your screen very well? Just rotate the view to fill your visualization area better.
  • Background Images: Display any image in the background of your visualization. Perfect for including your own logo in screenshots and movies.

In addition, the following improvements and minor enhancements are included in Via 1.5:

  • Agent Group from Transit Passengers: Directly filter out the ids of passengers of a transit line or just a single transit route during any time of day. Use those ids as Agent Group to selectively visualize Activities of those passengers only.
  • New Fancy Vehicle Style: The Fancy Vehicle Plugin now offers an additional vehicle style “night mode”.
  • Improved User Interface: The user interface was tweaked in multiple places to optimize for your visualizations. The toolbar now takes less space away, and several options have been directly integrated with toolbar buttons.
  • Improved XY Layer, Aggregator, OD Aggregator: These layers have all been heavily optimized for memory consumption and use now considerably less memory than before.

Working with Layer Styles

In this video tutorial, you learn how to define and use layer styles. Layer styles allow to quickly switch between different visualization settings.

Showcase: Seoul

The MATSim model of Seoul Metropolitan was developed in 2012 as a result of long-term research collaboration between the University of Seoul (Prof. Seungjae Lee) & ETH Zürich (Prof. Kay W. Axhausen), with additional support from Senozon. The model was updated on a yearly basis and the demand is generated based on 2012 Household Travel Survey Data (HHTSD).

The study area covers the Seoul Metropolitan Area. Population Synthesizer was developed to generate the MATSim input demand based on HHTS 2012. Total population of SMA is 21.5 million; therefore, a 10 % sample was generated and simulated (2.15 million agents). A detailed network of nodes and links was generated capturing all the details (16 384 nodes and 32 768 links) for railways, highways, arterials, pedestrians, expressways and bus only lanes.

The video was created by Atizaz Ali from the University of Seoul and shows a nice combination of various Via features.

Showcase: Singapore

At the Future Cities Laboratory in Singapore, a group of researchers uses MATSim to model the traffic in Singapore. They use Via to visualize their simulation results, and do so in a stunning way. They have created a video which explains in a few minutes what MATSim does and how it works and illustrate it with beautifully animated simulation results from the Singapore model. Have a look at the video on Vimeo, and make sure to watch in HD and full screen.

Via 1.4

After many hours of work, the new version of Via is finally ready! The new version, Via 1.4, comes with a lot of new features making your work faster and easier:

OD-Aggregation in Via 1.3

  • Improved GUI. the section showing the query results is now stand-alone and always visible
  • Layer styles. Easily switch between different presets on how to visualize your results.
  • Agent attributes. Load arbitrary custom attributes to your agents and use those attributes for visualization.
  • Multi-modal trips. Visualize the route of transit trips of agents, or differentiate the display of agents using different modes on the network.
  • Many new analyses. For transit routes, for facilities, for agents, …

These are just a few of many new and improved features in Via 1.4. Try it out for yourself and let us know what you think about it! We love to receive feedback on Via, as it keeps us making Via better and better for all of you.
