Should bus lanes be shared?

Hoddle St bus lane, looking north (off peak)

The Government’s announcement this week that motorcycles will be able to travel in the bus lane on Hoddle St for a six month trial period revealed a surprising diversity of views about who should and shouldn’t be able to travel in bus lanes.

At present, only buses and bicycles can use the bus lane on Hoddle St (it runs on the south side of Hoddle between the Eastern Freeway and Victoria Parade – there’s no bus lane on the northern side).

The reporter for The Age, Jason Dowling, did his homework and canvassed a number of organisations with an interest in the matter. The Government and the Victorian Motorcycle Council evidently favour buses, motorcycles and bicycles, but:

  • The RACV says the lane should be limited to buses and taxis
  • The Bus Association says only buses should be permitted
  • Bicycle Network Victoria is against motorcycles – it says the lane should only be used by bicycles and buses

I can’t see any problem with motorcycles and scooters using the bus lane. They’re fast enough so they won’t hold up buses and they’re small enough that they shouldn’t present queuing problems at intersections.  Although they’re not without problems (noise and pollution from two strokes), they’re a relatively efficient form of transport compared to cars and low occupancy buses. If cyclists can successfully share a lane with buses that barely fit, contending with motorcycles should be a cakewalk. Motorcycles warrant space in the bus lane.

However the logic of the RACV’s argument that taxis and hire cars should be able to use bus lanes is hard to fathom. There’s no environmental or equity benefit to be gained from making a trip by taxi rather than by car. The only real difference is that in one case you’re paying for a chauffeur and in the other you’re doing the driving yourself (although for a traveller from one of the 10% of Melbourne households that don’t own a car the equation would be different).

Taxis provide an important service, but they aren’t “public transport” in the meaningful sense of a vehicle shared by multiple passengers going to multiple destinations (except sometimes at the airport). They are “public transport” only in the narrow sense that they’re available to anyone for a price. That’s also true of rental cars and I can’t see any reason why they should get access to bus lanes either.

If anything, bicycles are probably the least appropriate mode to share with buses. They’re slower and hence can potentially hold buses up, depending on conditions. In order to overtake a cyclist safely, a bus on Hoddle St will need to enter the adjoining lane, thus weakening to some degree the whole point of a dedicated bus lane. Read the rest of this entry »


Should scooters and motor cycles have a bigger role in cities?

John Adams - On the transmigration of souls (Tribute for 9/11)

I’ve argued before that scooters and motorcycles should play a much bigger part in meeting our future transport needs if the cost of motoring increases dramatically in real terms (here and here). That’s because Two Wheel Motorised Vehicles (2WMVs) are cheap to buy, they’re economical to run and they offer many of the advantages of a car, including on-demand convenience and speed. Moreover they’re easy to park and can be threaded through traffic.

We know 2WMVs are very popular in countries like Vietnam where vehicle purchase and running costs are very high relative to incomes, yet they don’t have a high profile in discussions within Australia about how to deal with peak oil and climate change. Because of their low fuel use, small 2WMVs with efficient, clean engines should garner greater attention as a more sustainable transport option.

A new study published earlier this year, The unpredicted rise of motor cycles: a cost-benefit analysis, might help to give more prominence to the two wheel powered option. It shows use of 2WMVs grew strongly in Paris from the start of the new century, when real oil prices began to rise.

Pierre Kopp from the Pantheon-Sorbonne University (Paris-1) found the number of passenger kilometres travelled by 2WMVs increased 36% in Paris between 2000 and 2007*. This was much higher than other modes – rail grew 12% and bus and car fell 21% and 24% respectively. By 2007, 2WMVs accounted for 16% of all road passenger kms in Paris (up from circa 10% in 2000), more than double the share of buses.

The growth in 2WMV use was primarily at the expense of public transport. Of the 380 million additional passenger kms attributable to 2WMVs, a fifth were generated by existing riders travelling more and 27% by travellers transferring from cars. However more than half (53%) came at the expense of public transport.

This is not surprising given the evidence the author presents for the point-to-point time savings offered by 2WMVs over all other modes. Within Paris, they are 46% faster than cars and 50% faster than the Metro. Within the suburbs of the metropolis, they are 39% faster than cars and 34% faster than the RER.

The author calculates the switch from cars to 2WMVs generated an annual travel time saving worth €93 million. He subtracts higher accident, pollution and other costs, giving a net benefit of €102 million. The net benefit from those who switched to 2WMVs from public transport is €62 million. In contrast, the share of the additional 2WMV travel generated by existing riders has a net cost of €3.7 million (mostly reflecting the absence of the sort of dramatic time savings obtained by those who switched from relatively slow cars, trains and buses).

Parisians who switch to 2WMVs are motivated primarily by time savings rather than fuel costs. On the other hand, the main deterrent is safety (interestingly, the big cost component by far is minor accidents rather than serious ones or fatalities). The importance of safety is illustrated by the fact that all the value of the extra trips taken by existing riders was cancelled out by higher accident costs.

The total €160 million net benefit from increased 2WMV travel over the period was achieved with little official support, according to the author. For example, parking for 2WMVs is limited and the number of parking fines doubled over the last seven years. The author contrasts the relatively high level of expenditure on infrastructure aimed at making cycling safer with the paucity of expenditure on 2WMVs, even though, he says, cycling accounts for a mere 0.8% of all road travel (and 6 deaths p.a.) in Paris whereas 2WMVs account for 16% (and 21 deaths p.a.).

I think it’s unfortunate that bicycles and 2WMVs are cast in competing roles for funding, but it’s nevertheless puzzling why small capacity 2WMVs (I exclude big motor bikes) have such a low profile in public policy as a relatively sustainable transport option. This seems as true in Australia as it apparently is in Paris.

It’s puzzling because 2WMVs have many advantages. Compared to bicycles they can travel longer distances, are harder to steal, are more accessible to those who are infirm, can carry a passenger and goods, and riders don’t need to take a shower. Compared to public transport they’re faster point-to-point, they’re private, most of the financial cost is borne by the owner, and they offer on-demand availability. And compared to cars they use less fuel and can handle congested conditions better. Read the rest of this entry »


Should motorcycles have a bigger role?

Scooters and Motorcycles (SAMs) in Hanoi

Public transport, cycling and hybrid cars get a lot of attention as responses to climate change and peak oil, but the potential of scooters and small motorcycles seems to pass largely unnoticed. That’s a pity because powered two wheelers are the mode of choice in places like Hanoi where fuel prices are very high relative to incomes. They offer the key advantages of cars – on-demand response, a direct route to the traveller’s destination and speed – but at much lower cost. Indeed, if fuel prices go stratospheric, I expect a very large number of urban Australians will choose this mode of travel ahead of public transport.

A lot of policy attention is quite properly given to improving the safety of riders, but very little is given to developing scooters and motorcycles (hereinafter SAMs) as part of a comprehensive transport strategy. That’s unfortunate because there would potentially be many benefits for the wider society if they had a much larger share of all travel within our capital cities.

SAMs (and I include power-assisted bicycles in this category) have many attractions for riders. They are remarkably inexpensive to purchase and cost little to run. They can be ‘threaded’ through congested traffic, are cheap to park, and in some places they can be parked legally on footpaths. Most machines can carry a passenger and small items like groceries (or much more in Hanoi!). Most importantly, riders don’t have to wait for them, or transfer to another one mid-journey, or stop frequently, or take a circuitous route to get where they’re going. In most places they’re so easy to park that riders don’t have to walk far to them either.

Compared to the large proportion of car journeys that involve only the driver, SAMs also have many social benefits. They require only a fraction of the road space, consume much less fuel and emit considerably less greenhouse gas. They need little space for parking and don’t require new dedicated infrastructure (although some improvements to roads would help). Most importantly, they are potentially attractive to new classes of travellers because, like bicycles, they’re private and hence flexible.

The share of trips taken by SAMs may increase organically in the future in response to higher petrol prices and increasing traffic congestion. But given their social benefits, it would be good policy to actively encourage greater uptake of SAMs in lieu of driving. Safety is the key obstacle, so that’s where any strategy has to start. Current approaches to safety stress factors like rider skills and greater awareness of SAMs on the part of drivers. These are important, however within large urban areas the best strategy is safety in numbers. Achieving a critical mass of riders could be facilitated by initiatives such as lowering registration charges for small capacity SAMs, relaxing restrictions on lane-splitting, giving riders access to transit lanes, and increasing the supply of dedicated parking spaces (with locking points). There might also be scope for small works – for example, access lanes could be reserved to enable riders to move directly to the head of traffic at intersections.

But there are other important issues that need to be addressed too. Engines in SAMs are not generally as sophisticated in dealing with pollutants on a per kilometre basis as car engines. Nor are they generally as quiet under acceleration. These drawbacks are partly technical – it’s harder, for example, to incorporate catalytic converters in SAMs – but they can also be addressed through better regulations and more pro-active enforcement. In the medium term, electrically powered SAMs may mitigate some of these problems. Read the rest of this entry »
