Common Urban Myths About TransportMyth:
Trains and trams are obsolete and should be replaced with Maglev / Light
Rail / Monorails / Trolley buses / this year's trendy technology
Fact:
In the 1960s it was popular to think new technology would solve every
problem. In the case of transport systems at least, the technology has
failed to live up to the promise. Just as a humble Corolla will get you
to the shops every day just as readily as a rally-bred Ferrari, so the
attractiveness of public transport for day-to-day travel has everything
to do with service levels and very little to do with how much technical
prowess it demonstrates.
That old aphorism, "Technology is the answer, now what was the question again?" could have been coined specifically for application to urban transport systems. Scarcely a year passes when we are not treated to special features in the mass media on some fascinating new mass transport technology. In the sixties it was flying cars, monorails and automated people-movers: today it's wireless light rail, Very Fast Trains, magnetic levitation, guided busways, satellite tracking and smartcards. All too often these technological fads are fuelled by our very own transport planning bureaucracy, which touts them as magic solutions to attract people to public transport. The continued obsession of public transport planners both here and elsewhere with trendy new technologies may simply reflect the dominant influence of engineers within the profession. It is an engineer's job to understand and develop technology, and there is no question that the sensible application of new technology can sometimes make it easier to get around on public transport. But planning a transport system generally requires a quite different set of skills: skills that are all too frequently ignored in the rush to keep up with the latest technological marvel. Too often the emphasis is on technological inputs to the system, rather than the outputs that matter to passengers. Case Study: The SmartBus SagaIn Melbourne, there are many suburbs that until recently lacked any kind of public transport service on Sundays, while many more suffered from bus services running at Kafkaesque 70-minute frequencies that no-one with a choice ever considered using. To remedy this situation would have only required some old-fashioned planning skills and a little funding (which could come from savings made elsewhere in the transport portfolio, that those same old-fashioned planning skills would identify). Only in 2006 did the government take some tiny steps towards introducing Sunday bus services in many of these suburbs. But even these only run at 60-minute frequencies, providing no alternative to anyone with a car in the driveway. Part of the reason our planning bureaucracy fails to provide decent local bus services is that for many years it was busy spending millions of dollars on its original high-tech, high-cost, low-relevance idea for a 'SmartBus': satellite-tracking systems with real-time information displays on a very small number of limited-hours routes that probably didn't include your suburb (and didn't get any service improvements to match the gadgetry). Even years after being installed, those fancy displays were still less useful than a plain old paper timetable.
In November 2005 the Smartbus displays, after a history of continual malfunctions, were switched off permanently and a software redesign took place at a cost of $5.6 million. It turned out the new software would be incompatible with the existing signs, and as a result dozens of electronic signs were scrapped, with not so much as a replacement paper timetable to tell people when the next bus would run.
In March 2006, project coordinator Geoff Newbegin told the
Oakleigh Monash Leader the electronic signs would cost
The rejigged SmartBus signs remain in place, and now do a passably good
job of indicating the next bus departures. In other respects, however,
they have become even less useful. At Bentleigh, the electronic signs
used to display information for connecting train departures, but they no
longer do so: the But there is a moderately happy ending to this story. In response to public criticism and lobbying by the PTUA, the government eventually shifted its Smartbus focus away from electronic signs and toward the things that really matter: higher frequencies, and service until later in the evening. The current 'SmartBus standard' is service every 15 minutes until at least 9pm. (Mind you, not every service labelled a SmartBus actually meets this standard.) For this, SmartBuses have been rewarded with rapidly increasing patronage - more than enough to cover costs - which the signs by themselves failed to deliver. There is a lesson here that matches the experience in other cities. International Success Stories: No Fancy Gadgets, Just Good PlanningIf bus services were frequent and reliable there would be no point to having real-time information, as one could simply turn up knowing that a bus will arrive within a few minutes. At best, real-time information might be just a nice add-on, like TramTracker on the tram system, rather than something you do instead of fixing up the service. This is the attitude taken in Toronto, where bus patronage is an order of magnitude higher than in Melbourne, though there are no real-time displays. Toronto is in fact so technologically backward, public transport-wise, that until a few years ago it still ran trains similar to the blue 'Harris' cars that Melbourne stopped using around 1980. Nonetheless, those old trains carried three times as many passengers as the San Francisco BART, a 'space age' mass-transit system that is not only larger than the Toronto system, but also serves an area with a higher population. The city of Zurich has some of the most successful public transport in the world. Yet it has no Maglev, no O-Bahn, no monorails and no ultra-high-speed trains. This is not for want of trying by the city engineers: in 1962 they floated a proposal to put the main tram lines underground and replace the rest with 'space age' buses; in 1973 there was a similar proposal for a new metro system, not unlike the BART which dates from the same period. As both proposals were defeated by referendum, this required the planners to find another way to make trams run efficiently in city streets. Their solution was to systematically remove all impediments to the movement of trams, through such mundane measures as adjusting traffic light sequences, installing concrete kerbs between tram and car lanes, and declaring turn bans at certain intersections. The measures were so successful that they are now employed in a large number of European cities. Another Swiss invention is the 'pulse timetable', where inter-city trains converge on a single location five minutes before the hour and depart for other locations at five minutes past the hour, allowing anyone to transfer from any service to any other in just ten minutes. No fancy technology is required, just a few planners with a brain between them. Transport planner Paul Mees sums up the shift which has taken place from the big capital-works projects of the 1960s to the more subtle planning interventions that have made public transport successful in cities like Toronto and Zurich:
The Pitfalls of Too Much TechnologyPerhaps if there were a bottomless pit of money to spend on public transport infrastructure and services, our planners' obsession with costly technological 'solutions' would be harmless enough. Unfortunately, the technological approach often leads to a destructive conflict between transport modes, as supporters of rival technologies compete for planners' attention. In Brisbane, for example, the current planning orthodoxy supports busways because these are thought to be an 'optimal' public transport technology. The first of these to be built was the South East Busway, which runs parallel to an existing railway line and actually runs for part of its length on land released by tearing up one of the tracks on this line. Trains in Brisbane are underused for the same reason as trains in Melbourne, because of the lack of feeder bus services to railway stations. Buses that could be feeding people to a faster, higher-capacity rail system are instead taking people on parallel routes all the way into the city, because of the attitude in planning circles that trains and buses are somehow in competition with one another instead of capable of forming a network.
In no Australian city, however, are suburban trains as underused and neglected as in Adelaide, which now holds the title of Australia's most car-dominated capital city. In part this is due to Adelaide's 1980s experiment with another pet technology, the 'O-Bahn' guided busway. The O-Bahn technology was imported from the German city of Essen, where it was invented in order to allow buses to share existing tramway tunnels, and has yet to be replicated anywhere else (although other incompatible guided busway technologies are in use in Japan and the UK, and share many of the O-Bahn's drawbacks). Currently, according to official sources, the dozen or so Adelaide O-Bahn routes together carry around 7 million passengers a year - equivalent to the average for just one of Melbourne's two dozen inner-city tram routes. However, even this modest level of patronage is significantly greater than for any other public transport service in Adelaide, leading to the impression that the O-Bahn is 'successful', even if by world standards this is really not the case. Like Melbourne, Adelaide has the urban geography and a large part of the established infrastructure necessary to support vastly improved public transport, based on a seamless network of train and bus services. New technology could also play a part where it is appropriate, cost-effective and fulfils a clear need. However, Adelaide's O-Bahn exemplifies most of the pitfalls that can arise when adopting 'novelty' technologies like busways, monorails and Maglev trains:
Much the same observations applied to the ill-fated 3.6km Sydney monorail. This was built in 1988 at a cost of $70 million (or $20 million per km, three times as much as Perth's Northern Suburbs railway), and catered primarily to tourists, with a carrying capacity less than Melbourne's trams. Ever since 1998 when the original operator decided to sell up, there had been calls to dismantle it due to the unsightly nature of the elevated rail. It was eventually acquired by the NSW Government and decommissioned in 2013. Brisbane's busways, to be fair, are relatively low-tech. They use ordinary buses and don't rely on specialised technology. But even they, like the O-Bahn and the Sydney monorail, have not lived up to their claim to be a low-cost alternative to rail (which they are largely duplicating). For example, the 4.5 kilometre, $30 million extension of the South East Busway to Springwood had a slightly higher cost per kilometre ($7 million) than the suburban portion of the Mandurah railway in Perth ($6 million). The first section of the Eastern Busway, meanwhile, is a 1km tunnel that cost $465 million, and whose entrance is less than 1km from the nearest station on the parallel train line. For less than $10 million worth of well-designed interchange facilities, buses from the eastern suburbs could have coordinated with the train network instead, saving over $400 million in the process. Conclusion: No Technology is 'Optimal'Vukan Vuchic, Professor of Urban Transportation at the University of Pennsylvania, observes that there is no one optimal public transport technology. Rather:
A telling contemporary example is Curitiba in Brazil. For many years, Curitiba's popular high-capacity 'bus metro' has been touted as a living example of the 'optimality' of buses and their superiority over rail as efficient mass transport. Curitiba is now, however, looking at converting its central core bus services to rail at a cost of $680 million. Buses are a very successful mode of transport in Curitiba, but as the city continues to grow, a multimodal system becomes more compelling. The transport needs of ordinary people in cities are best met by well-planned public transport services that build on what already exists. New technology can help improve the speed and efficiency of these services, but one must never lose sight of the need to apply good planning skills to the technology in order to make it work for passengers.
