Banedanmark TMS Presentation at TRB

I’m giving a presentation on the Banedanmark (railway) Traffic Management System (TMS) project at the US Transportation Research Board Annual Meeting on Tuesday January 12, 2016.

Banedanmark, Denmark’s national railway infrastructure owner, is completely replacing the country’s railway signalling system with a European Rail Traffic Control System (ETCS). The digital data from the ETCS, combined with improved technologies for managing staff and resources, provides the foundation for developing an advanced TMS that can significantly improve railway efficiency and attractiveness.

Banedanmark’s TMS takes a fresh approach to railway operations by creating Production Plans consisting of precisely defined tasks to be carried-out in operating the railway. Production plans are developed based on a very clear definition of customer needs called Service Intentions. Banedanmark’s approach integrates planning and operations by using the same algorithms and data. It improves the precision of planning and provides updated Production Plans quickly enough to significantly reduce the impact of delays and disturbances.

I’ll explain more about these concepts at the presentation. In the meantime you can download a PDF of the presentation: Banedanmark TMS: ETCS as the foundation for attractive and efficient railway service.

My Ring Ride – Ringstrasse150 project is being awarded an honourable mention award at the 2016 US Transportation Research Board Annual Meeting – Yea!

Here are my presentations and papers at the TRB Annual Meeting – Sunday 10 January -to- Thursday 14 January 2016:

  • Repurposing Travel Lanes for Multimodal Projects – Workshop 114 – Analyze This! What Planners Want to Know; Andy Nash, Green City Streets with Natalie Stiffler, City of Boulder. The workshop considers three problems, our problem considers the evaluation of and communications about the potential congestion impacts of sidewalk widening, bike lane, and transit lane projects. We’ll use Boulder’s Folsom Street project as a case study and try to develop strategies for improve the evaluation of these projects and communications about congestion. Sunday 10 January – 9:00 AM- 12:00 PM, Convention Center, 140A.
  • Enhanced Resource Conflict Graph Rescheduling Model for Freight Rail Traffic: Introducing Energy Saving; Toletti, Ambra, Valerio De Martinis, Ulrich Weidmann and Andrew Nash; Monday -1:30 PM- 3:15 PM – Session 367 – Current Research on Freight Rail Transportation, Convention Center, 149.
  • Tram Safety in Mixed Traffic: Best Practices from Switzerland; Improving Light Rail Through Operational and Safety Analysis – Marti, Christian, Jonas Kupferschmid, Michael Schwertner, Andrew Nash, and Ulrich Weidmann;  Monday – 7:30 PM- 9:30 PM – Session 470 – Convention Center, 143A.
  • Banedanmark TMS: ETCS as the foundation for attractive and efficient railway service; Nash, Andrew; Tuesday – 8:00 AM – 12:00 PM – Intercity Passenger Rail Committee, Marriott Marquis, Capitol (M4).
  • Evaluation of Freight Train Energy-Saving Potential Using Onboard Monitoring Data; De Martinis, Valerio, Ulrich Weidmann, Andrew Nash; Tuesday – 10:15 AM- 12:00 PM – Session 576 – Energy Efficiency Technologies for Rail Transportation – Convention Center, 147B.

Hope to see you there!

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

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

Amsterdam Central Station - 1

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:

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.
