They then went on to look at, 'Okay, so what are the additional policy levers that might fill the gap and generate the scale of change', which, in their first report, they identified was necessary. So, they started by looking at, if you like, the logical extremes, in terms of making motoring more expensive, and making bus travel free—so, the ends of the spectrum, if you like. So, you could do it through making motoring more expensive. Their research suggests that, in order to generate the scale of change needed, you would have to increase the real cost of motoring by about 4.5 per cent per year in real terms, each year from now until 2050, which, obviously, is politically somewhere on the scale from 'difficult' to 'impossible', I'm sure.
The other end of the spectrum—making buses free—would be very, very expensive and would actually have limited impact. Most of the benefit of the policy would go to people who already use buses, and that may well be something that Government decides is a good thing to do for its own purposes. But, as a contribution to the modal shift required, it's actually pretty poor value for money—so, expenditure of about £150 million per year, which would generate around 11 per cent of the total modal shift that is required. So, no surprise really that they concluded that modal shift was very, very unlikely to be about single policies, and you actually need a package of complementary measures.
So, what we did with WPI and with the Social Market Foundation, over the course of last summer, was run a series of seven, I think, round-tables across the country to identify what might go in that package of measures. There's a very, very long list of possible policies in the annex to our report, but, broadly speaking, they fall into three categories: one, you can make the bus network more attractive—you can make it bigger, more frequent, better services, better quality of buses. Secondly, you can make buses cheaper. And against those two carrots, you've got the stick—option number three—of discouraging the use of cars, by making car travel relatively less attractive. Underpinning all of those, although it is very, very hard to research because there are very few examples of it actually taking place, you've got a range of behavioural interventions, or nudges, that might influence consumer choices, on top of those three measures.
So, WPI very consciously didn't try to design a particular solution—they didn't try to come up with all of the answers in the time available. But what they did model for us were some examples of the sort of scale of intervention in each area that might be necessary. So, under the—sorry, this font's so small, I'm struggling to see it from here—under the category of 'Increasing attractiveness of bus network', they looked at what's been going on in England in recent years, where all local authorities have been invited to bid for funds to improve their bus network, and said, 'Let's take that as a marker of what's needed, and let's take that per capita amount and assume that that amount is spent in Wales, in this case, as well'. And they called that an 'ambitious investment' in the bus network, totalling about £1.8 billion over the period in question.
