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.

Via 1.3

OD-Aggregation in Via 1.3

We’re happy to announce the new version 1.3 of Via, our analysis and visualization software for MATSim. The new version comes with many new and improved features which we hope makes the work with Via even more enjoyable. The following list highlights only the major changes in the new version. The get the full impression, head over to download the new version and give it a try!

Highlights of the new release:

  • Visualize your data faster. Via can now automatically create layers when you add some data. Just drop some network or shape file onto Via, and it can automatically create a layer for you.
  • Visualize more data. From what we hear, our users love the XY layer to quickly visualize some custom data they have, be it either from data that has to be converted into MATSim formats, or results from custom analysis scripts they have. Well, the XY layer got now even better! It supports now CSV files, tab-separated TXT files, and even GPX files. Yes, just add the GPX files from your GPS recorder to Via, and you can see your GPS points wander around the screen.
  • Improved interactive queries. Have you ever wondered what bus lines run along a road, or how many departures are at a specific stop facility? These and many other questions can now be more easily answered as query results give you direct access to new depending queries. Jump from links to transit lines and stops to passengers in no time.
  • New aggregation analysis. The agent-based approach certainly is very useful for the simulation and analysis of the agents’ behavior. But at the end of the day, it’s still easier to communicate with aggregated values. Our first new plugin since the initial version of Via helps you with exactly that: filter and aggregate data into arbitrary zones, so you quickly get a better understanding of your data.The Tel-Aviv scenario shown on MATSim’s website shows some data aggregations done using Via, as does the image just above.

We hope you like these and the many other improvements we made to Via, but if you still miss some features, let us know! We’d love to hear from you and try to integrate your feature requests into one of the next versions of Via.
