Last month I wrote about the importance of evidence. The month before I wrote about how averages can’t always be used as evidence of what society needs from transport planners. And this month I have even more evidence of how little society may reflect averages.
The University Transport Studies Group annual conference was packed full of papers presenting ongoing or recently completed research from senior academics down to PhD students. The standard was high, and much of the work fascinating. A presentation offering an historic overview of urban transport policy by Professor Peter Jones of University College London best elucidated one conclusion I’ve been coming to over the last year – that we need to move from a ‘Predict and Provide’ to a ‘Vision and Validate’ model. To do this, transport planners must work with other sectors to change how their needs for accessibility can be met in order to meet mobility demand sustainably – and flexibly.
Flexibility is key. People’s need for mobility is dependent upon their need to access activities, goods, and services. As I’ve noted before, more and more people already maintain their accessibility in different ways at different times for different purposes. Their patterns of access can be variable instead of habitual. And between different people or groups of people, there is even more heterogeneity.
For example, there was a presentation on the night-time economy at the conference. I can’t say I’d given much thought to these sorts of workers before. Neither, it turns out, have policy-makers, who have focused on access to places of food, drink, and entertainment for the customers, ignoring those who work in these venues, who might require different travel options than those they serve. Never mind other 24-hour services, such as health and social care, or transport and logistics. How can we envision and plan for transport networks that work for these people, as well as the day-time commuter?
Various presentations also investigated whether ‘Mobility as a Service’ was a realistic scenario for the future of transport. There remain many barriers to its implementation and success. Not least if such services cannot match the flexibility of those most likely to sign on. One paper estimated that Mobility as a Service is of most interest to those who have private vehicles, but only drive their cars 1-2 days a week. Yet as noted in previous blogs, do our current methods of surveying and modelling sufficiently capture such regular, but infrequent behaviours that they enable the design of services catering to these people?
Another paper found that by looking at different data sources and then interrogating the results of one source with the results of the other, travel behaviours that seemed regular and even habitual masked variation. Those who travelled along a stretch of road regularly were more likely to vary their time of travel, whilst those who travelled less regularly were less likely to vary their timing. Getting the right messages out to these irregular travellers, who might not be familiar with their location or choices, is challenging. Yet, it is these people who most need advice, if, as another paper pointed out, they feel they can understand and trust that advice.
Trust is also key for all the ‘shared transport’ that we are apparently ever more willing to use in the 21st century, and, without which, many of our visions for a technologically-advanced, but sustainable future fall apart. However, to note the topic of one final presentation, we would do well to remember that not just vehicles, but roads too are a shared resource. And we don’t always trust each other to use even those flexibly and appropriately!
In conclusion, let’s hope for a New Year that brings not only transport research and policy development that supports flexibility and variation rather than habits and averages, but also a resolve to be a bit more flexible ourselves.
