Ringstrasse150 Project Launch

Ringstrasse150 Project Launch

We’re excited to be launching the Ringstrasse150 – Ring Ride project. The project consists of a website with information on improving walking and cycling in Vienna and a mobile phone game designed to increase engagement by linking to the website in the game results screen. The website is available here:


We’ll be working on the website in the next few days to finish the German version and improve the content.

The Ring Ride game is available for Android from the Play Store:

The iOS version will be available as soon as it it approved by Apple.

We have rethought the project since our original idea for a website that would include mapping of improvement ideas. Instead the website now focuses on being a “one stop shop” for presenting information about how to improve walking and cycling in a city – in our case Vienna’s Ringstrasse. We’ll add learning elements to the website later. The main reason we decided not to include improvement mapping is that many cities already have these websites (including Vienna), so we’ll focus on trying to get people to use these existing websites.

If this project is successful similar websites could be developed for other cities following the same model. Here’s more information about the project and what we hope to achieve.

The goal is to increase support for walking and cycling improvements by creating a game (Ring Ride) that will introduce new people to organisations, activities, ideas and resources for walking and cycling in their cities.

Strategies for Reducing Passenger Congestion in Rail Stations: European Case Study

Strategies for Reducing Passenger Congestion in Rail Stations: European Case Study

In January I’ll be making a presentation about my recent research on using new technologies (mostly) to help reduce passenger congestion in rail stations (metro, regional and long-distance railways). The presentation’s original title was more exciting, “Passenger Congestion at Rail Stations – the Good, the Bad and the Ugly” but as the research progressed it became clear that focusing on solutions, and especially ideas for using applications and new technology (since standard design practices and modelling are fairly well understood) made more sense. Here are the details:

  • San Francisco – SPUR – Thursday January 8, 12:30 PM
  • Washington DC – Transportation Research Board Annual Meeting: Workshop 194: Rail Station Congestion Management and Capacity Expansion; Sunday, January 11, 2015 1:30PM – 5:30PM Convention Center, 147A.

Here’s a link to the presentation: Thinking outside the station: Addressing rail station congestion in Europe.

Public Transport Strategic Planning using Levels

Public Transport Strategic Planning using Levels

I’m making a presentation at SPUR in San Francisco on January 7 on the concept of public transport network level and using it to describe the performance and future improvement of Zurich’s public transport system.

A public transport level is a specific type of service designed to serve a particular market. Service is defined as a combination of vehicles, infrastructure and operating characteristics. A “pure” level is when the service is targeted specifically to one particular market. A “hybrid” level is when a service is targeted to serve several markets. Urban travel is generally described as three markets: short, intermediate and long distance trips.

Consequently many cities have developed three-level public transport networks: surface buses and trams to serve short trips, rapid rail to serve intermediate trips, and regional rail to serve longer distance trips. Often, by design or for historic reasons, cities have additional levels, fewer levels and/or the levels that are not precisely matched to their markets. For example, two-level networks are often found in medium size cities. Their advantage is lower costs while their main disadvantage is a mismatch between transport mode and market that manifests itself in capacity limitations.

Using the level concept to help analyze and plan public transport service is useful because it focuses attention on matching service qualities to markets. The presentation will use this approach to analyze the success of Zurich’s public transport system and to provide a structure for planning improvements that will be needed to meet rapidly increasing public transport demand. This approach could help other cities (re)design their public transport systems to be more attractive and efficient. More specifically, the approach could show how two-level public transport networks could be a viable option for medium sized cities and large cities with dispersed settlement patterns.

My co-authors Hermann Orth and Ulrich Weidmann are also presenting the paper at the Transportation Research Board Annual Meeting: A Level-based Approach to Public Transport Network Planning; Session 514: Public Transportation Planning and Development: Food for Thought on Networks Design, Accessibility, and Investment Policy Tuesday, January 13, 2015 8:00AM – 9:45AM Convention Center, 149.

Here’s a link to my slides: A Level-based Approach to Public Transport Network Planning now online! now online!

(2019 Update) … Information from the website is now available on

(Original from 2014) … The new website is now online and it’s much improved. I’ve made “” the umbrella name for all my work in the field of using information technology applications to improve public participation. Consequently I’ve described the work that was done as part of the BusMeister project in 2011 and 2012 as the BusMeister project.

The new website will present an analysis of the latest ideas in using information technology applications to improve public participation. It describes the following activities:

The website includes pages on each of these subjects (click the link) as well as blog postings with new ideas.

The website also includes links to our games (BusMeister, Grr-Grr-Bike, Working on the Railroad) and projects.

The website is still a work in progress so check back again in the future and let me know if you have suggestions or ideas. In the meantime, we hope you like the new site!
