Melburnian’s seem to love trains and dislike buses. Melbourne Airport and Doncaster are both served by high-frequency bus services with a wide span of operating hours, yet large numbers of people want to spend billions replacing them with trains.
The list of criticisms of buses – relative to trains – is long. Right at the top is slowness. Buses operate in traffic, follow circuitous routes, stop frequently and idle while passengers dig out spare change to pay the driver. They’re uncomfortable too. Shelters are perfunctory, the ride is jerky and difficult if standing, seats are jammed too close together and too many drivers don’t seem to actually like passengers. And buses are unreliable. They’re invariably late and if you miss one the wait for the next one will seem interminable. If it’s night or a weekend there’s a good chance that was the last bus for the day.
Then there are systemic criticisms. Buses aren’t ‘legible’ — prospective passengers can’t see where the route goes. Sometimes routes vary over the course of a day. Buses are also impermanent. Developers are less inclined to risk investing along a route if it can be changed overnight or even removed. And there’re hard-nosed criticisms, too. Buses don’t carry many passengers. Operating costs are high because each vehicles requires a driver. Per capita GHG emissions and energy consumption are no better than cars. Engines are noisy and polluting.
As things stand, buses look pretty bad compared to trains, even given the unreliability and crowding that characterises peak hour train services in many Australian cities. Buses have a serious image problem, not just here but in many western cities.
But it’s an unfair comparison*. The key reason buses are perceived so poorly relative to rail is they are mostly assigned to marginal routes with low patronage. Operators follow indirect routes and stop frequently to maximise revenue; they reduce frequency and hours of operation to minimise costs. They can do that because their customers aren’t usually sophisticated CBD workers but travellers who are mostly “captive” to public transport. In other words buses mostly operate in a different market to trains. But it’s given them a bad reputation.
Most of the criticisms can be fully addressed, or at least softened, when the comparison is like-for-like i.e. when buses operate the sorts of long-haul commuter services that urban rail is customarily used for in Australia. Bus Rapid Transit (BRT) systems typically have high patronage and operate in their own right of way (just like trains) or in dedicated on-road bus lanes. Stops are major interchanges spaced kilometres apart and tickets are bought before entry.
BRT vehicles can be made with the internal look and ‘feel’ of (light) rail and the jerky ride can be minimised with electric engines. Articulated buses carry large numbers of passengers and can provide better leg room. According to Corinne Mulley, Chair in Public Transport at Sydney University, Brisbane’s South East Busway carries 15,000 passengers per hour and in Bogota buses carry 45,000 per hour. She says “US evidence points to infrastructure costs for dedicated buses being approximately one third of light rail costs”. As a point of reference, Eddington forecast that a Doncaster rail line would carry up to 12,250 one-way trips per day. Read the rest of this entry »
