– Can parking be managed better?

SFpark, San Francisco's experiment with dynamic pricing of parking spaces

I’m disappointed by the discussion of parking in Melbourne City Council’s draft Transport Strategy Update 2011-2030 (note – it’s a big download). There’s an opportunity to improve the efficiency of parking space allocation through using technology and pricing in combination, but Council seems content to pass on it.

The broad thrust of the discussion in the report is that the number of on-street parking spaces will decline over the next 20 years to enable public transport and amenity improvements to be implemented. Council is mindful of the impact this will have on its own revenues and those of local businesses, but is persuaded by the social and environmental benefits.

A key recommendation in relation to on-street parking is that Council “will implement new parking technology systems that allow payment without requiring parking machines or meters (and) will remotely sense and assess parking occupancy”. Surprisingly, this recommendation is entirely unsupported by any explanation or discussion. As far as it goes, it nevertheless sounds good – it’ll lower costs by eliminating the need for parking inspectors and it’ll give drivers more flexible payment options.

What seems to be missing, though, is the opportunity to provide drivers with real-time information about parking availability. More importantly, it squibs the opportunity to improve efficiency in allocating parking spaces by setting a price that’s responsive to demand.

The current pilot project just introduced in San Francisco, SFpark, gives a sense of what can be done. Like Melbourne City Council’s plan, it involves sensors that automatically sense if a parking space is empty. SFpark however will convey that information to drivers electronically via a smartphone app. That should reduce the time drivers spend cruising for parking. According to Donald Shoup, a Professor at UCLA and the author of The High Cost of Free Parking, several studies have found that cruising for curb parking generates about 30 percent of the traffic in CBDs in the US. He cites a study he did of a 15 block district in Los Angeles where cruising for on-street parking created 950,000 miles of excess vehicle travel per annum, in the process consuming 47,000 gallons of petrol and producing 730 tons of carbon dioxide.

But the real innovation of SFpark is that prices are adjusted in real time in response to rises and falls in demand. The objective is to ensure that, on average, there is at least one vacant space in each city block:

SFpark will adjust meter prices based on demand to encourage drivers to make trips in off-peak hours and to use parking lots and garages. While high-demand spaces will gradually go up in price, other spaces will decrease in cost……Once a space is found, longer time limits and new meters that accept credit and debit cards will make it easier to avoid parking tickets.

W Class trams – is this a great opportunity?

Posted: August 17, 2010 | Author: | Filed under: Public transport | Tags: , , , , , , , | 3 Comments

Melbourne’s W Class trams have serious limitations when it comes to doing what urban transit systems are supposed to do – move people around efficiently and quickly.

But they might potentially provide enormous benefits – particularly in relation to tourism and city “branding” – that could make their continued operation (and expansion!) more than worthwhile.

Twenty five W Class trams currently operate on the 78/79 route (Chapel St) but the Minister for Transport says they will be phased out by 2012. Another twelve operate the free City Circle route. There are possibly another 200 W Class trams in storage.

While they exude history, they are old and more like museum pieces than components of a modern public transport system. The youngest models were built in the 1950s, but the design dates from the 1920s. So there is no denying that the W Class has many shortcomings for use on a contemporary transit network.

They are slow. They are not air conditioned. They don’t have low-floor access. They are extremely noisy. They are bumpy. They do not offer adequate protection to the driver in the event of a collision with another vehicle unless they run at speeds lower than 40 Km/hr. On mixed routes they would hold up faster and more efficient trams like those operating on the 109 route, preventing them from being used to their potential. Read the rest of this entry »
