High Speed Rail – Challenges and Opportunities for California

While in California last week I attended a high speed rail seminar organized by the University of California’s Institute of Transportation Studies and the Global Metropolitan Studies Center. The seminar consisted of six UCB professors talking about challenges and opportunities associated with the proposed California high speed rail system. The seminar was excellent.

Professor Carlos Daganzo gave the first presentation. He showed convincingly how high speed rail can bring down the total cost of travel given the expected increase in travel demand combined with the HSR’s decreasing cost per passenger model. This means that there is a very strong case for subsidizing high speed rail in the early stages of development, since it will improve the overall transport system.

Daganzo also believes that high speed rail can have a transformational effect on local public transport. This means that cities will seek to improve public transport linkages to the HSR stations creating a positive feedback loop leading to better integrated local-long distance public transport systems.

Professor Mark Hansen spoke next. Hansen looked at the relationship of HSR to air travel. He believes that with HSR the air travel market will become less competitive and that the reduction in flights will be most evident in secondary airports (only a small share of SFO, LAX and SAN flights are intra-state … although they use more than their share of capacity since they are generally smaller planes).

Hansen described research on proximity of Japanese HSR stations that shows that small differences in accessibility make a big difference in demand; therefore stations need to be very carefully located and highly accessible. Finally, he suggested that the best strategy for airlines is to fully integrate their systems with HSR by adopting an intermodal strategy. Interestingly he suggested that this strategy could be ad-hoc, for example, when there is bad weather airlines could shift passengers to HSR.

Professor Robert Cervero spoke third and described the land use impacts of high speed rail systems and joint development. He reflected that there have been many studies of the impact of rail on development. Most of these have shown that rail increases development of downtown areas (it would be impossible to have such dense downtowns without rail systems bringing in workers), increases commuter sheds (people are traveling longer distances to access jobs) and that transit oriented suburban development is very hard to accomplish (it needs very strong political support).

Cervero proposed four lessons for California: (1) station siting is critical, building stations in freeway medians or surrounded by free parking will lead to more sprawl development and greater driving; (2) feeder systems are important for solving the “last mile” problem, extended TOD corridors are a good solution; (3) TOD as a necklace of pearls (e.g. like Copenhagen’s approach) would be excellent, but California’s current planning regime does not support this approach; (4) joint development must be high quality and pedestrian-oriented, studies of joint development in Hong Kong show that these types of joint development can be much more effective than the alternative basic systems.

Cervero ended with the warning that, the high speed rail planning must carefully consider land use or it will simply fan the flames of sprawl development. California needs institutional reform to make effective land use planning possible.

Professor Elizabeth Deakin was the fourth speaker. She described results of a study she had done for the California High Speed Rail Authority for several Central Valley cities on how they could use HSR to revitalize their city centers. Her presentation was fascinating because she was able to show how these cities could use infill to grow into much more sustainable places while maintaining local building styles and character. Her drawings and planning maps helped illustrate the great potential HSR has for creating livable and environmentally sustainable cities.

Professor Arpad Horvath talked about the full life cycle environmental impacts of HSR. His main point was that HSR needs to be well used to be a more sustainable form of transport than automobiles or airplanes. However, if well used, HSR would be good for the environment. Another important point was that much of the electricity generated for California has a high level of sulfur dioxide (SO2), which means that HSR would generate more SO2 than driving or flying (on a per passenger KM life cycle basis), therefore, as part of the California HSR project, the state needs to develop alternative sources of electrical energy (not a bad idea).

Professor Samer Madanat, Director of the ITS, summed up the main points and moderated the question and answer period. He emphasized the fact that most of the speakers emphasized the need for good feeder systems and improved land use planning to make HSR successful.

The seminar was an excellent overview of ideas for making high speed rail in California more successful. The ITS is trying to develop an organized center for continuing and expanding this interdisciplinary research, I hope that they are able to attract the funding and support necessary to create the center.

Swiss Travel System Video Contest – Bad News For Andy

Unfortunately my video entry for the Swiss Travel System Casting competition was not selected. Since I won’t be heading to Switzerland, maybe somewhere else would be nice? Check out the video.

By the way, the Swiss Travel System Casting competition was lots of fun and congratulations to the winners! You’ll really enjoy Switzerland and its fantastic travel system.

Westbahnstrasse Tram Track Reconstruction

Our local tram (US: streetcar) line has been closed for a little over a week while the Wiener Linien rebuilds the track. The work has been going on for about three weeks (the trams kept running for the first couple weeks) and will continue until early next week.

Track maintenance is a massive undertaking, they started by tearing out everything until they reached the dirt (about 70 cm, 2.5 feet), then they rebuilt it step by step. First repairing the sub-base, next building a new poured concrete track support system, then replacing the tracks and finally placing a new roadway surface (prefabricated sections).

They are working on approximately three blocks this summer, doing one block at a time. The first block is finished, the second is just about finished and they started on the third block yesterday. They are also replacing a shorter section at Westbahnstrasse and Kaiser Strasse which involves a tram line crossing – the photo above is from that construction.

Here’s a link to my 230 (so far) Flickr photos of Westbahnstrasse tram track rehabilitation.

I also have been filming some of the action, I will make a website with the best photos and films in the coming months.

Moving Sidewalks: Back to the Future?

There’s a great article on the history of moving sidewalks in New Scientist Magazine (thanks to Planetizen).

I think moving sidewalks, or some other type of continuous transport system, would be a great feeder system for regional (US: commuter) rail systems. This would enable the stations to be located a bit further apart in urban areas than in a ‘normal’ subway system – reducing operating costs and making service on the regional system more attractive (fewer stations = faster). Regional rail systems build with this model could follow the Zürich S-Bahn model, many lines operating through a central section that branch to different suburbs when they leave the center.

An interesting compliment to the moving sidewalk/continuous transport system would be combining it with attractive urban design, in other words give the people traveling on the system something interesting to look at while traveling. I recently had the idea of creating such a system in Abu Dhabi as part of their new Metro project. In this case the continuous system could travel through a traditional Arab linear market street setting. The market street would be protected from the weather in traditional ways, thus reducing energy use. The project would combine ‘new’ urban development with the transport system. More on this idea later.

Museum Tauernbahn: Austrian Railway Museum

A couple weeks ago we visited the Museum Tauernbahn Salzburger Eisenbahnmuseum (the Tauern Valley Railway Museum). The museum presents the history of the railway line that connected Salzburg with routes to Trieste (the main port city for the Austrian-Hungarian empire.

The museum is small but quite nice. You can reach it by taking the train from Salzburg to Schwarzach St. Veit – about one-hour trip. The museum is a few steps away from the station. If you come by train they give you a discount (3 Euros instead of 4-5 Euros).

The museum focuses on building the rail line through the alps. It has an old tunnel drilling machine, describes the construction process, the history of selecting the alignment and has a model of one of the worker bedrooms. Outside you can climb on an old locomotive and there is an old maintenance hall with exhibits on the signalling/interlock technology, power distribution and a model “station”. Upstairs is a model railway (currently being completed) of the rail line.

The museum is open from May to early October Wednesday, Saturday and Sunday (and some Thursday nights) – check the internet site for details. The descriptions are in German, but the people are very helpful and many of the exhibits are self explanatory.
