Transportist: Fifty Ways to Please Your Funder
A conversation with ChatGPT to identify "The Great Unknowns in Transport Research"
Following up on the February Transportist, a few people replied.
RN:
The one area that needs more research is into political and institutional elements of transport decision making, which I think you get at - that is, we know the answers but we don't know how to get policies implemented. The institutional inertia of engineering-oriented agencies is a big part of the problem.
SD:
What would be the consequences of drastically raising the cost of drunk driving (and DUI)? For example, anyone caught driving drunk once will have their insurance jump by a factor of 10 instead of the factor of 2 or so that it is currently. Considering more than 10000 fatalities per year in the US alone due to drunk driving despite a gradual decrease over the years, would this lead to a faster reduction of those?
[Or better yet, if convicted of drunk driving you would be imprisoned so you couldn’t drive again. On this topic, we know that countries that have steeper penalties for drunk driving, not surprisingly, have less drunk driving. The question in my mind is why US society especially tolerates drunk driving, and even elects drunk drivers as President, with a ‘boys will be boys’ attitude.]
On the larger question, I figured I would ask the oracle, ChatGPT, a compressed container of all human knowledge [read that link by Ted Chiang, it’s excellent, I will wait], what are the unknowns in transport research.1 2
So below you now have more than 50 proposal topics to inspire your imagination. But as a reviewer, I will be skeptical if I see any of these in the proposals I am asked to review.

Go deeper on item 5, how would one incorporate environmental factors into measurements of transport access.
Incorporating environmental factors into measurements of transport access is a critical aspect of sustainability. Environmental factors, such as air and noise pollution, greenhouse gas emissions, and energy consumption, can have significant impacts on public health, the environment, and the quality of life in communities.
To incorporate environmental factors into measurements of transport access, it is necessary to:
Develop comprehensive indicators of environmental impacts: Indicators such as emissions of greenhouse gases, energy consumption, and exposure to air and noise pollution can be used to assess the environmental impacts of transportation systems. These indicators can then be incorporated into measures of transport accessibility to provide a more comprehensive picture of the sustainability of transportation systems.
Consider the life cycle of transportation systems: It is important to consider the entire life cycle of transportation systems, from the extraction of raw materials to the disposal of end-of-life vehicles, in order to understand their full environmental impact. This includes considering the environmental impact of production, use, and maintenance, as well as end-of-life disposal.
Use a multi-modal approach: To achieve sustainability, it is important to consider the environmental impact of all modes of transportation, not just cars. This means taking into account the environmental impact of public transportation, walking, and cycling, as well as the environmental impact of private vehicles.
Consider the geographic context: Environmental impacts can vary greatly depending on the geographic context, such as urban, rural, or suburban environments. It is important to consider these differences when evaluating the environmental impact of transportation systems.
Use scenario analysis: Scenario analysis can be used to model the environmental impact of different transportation systems under different conditions, such as changes in population, land use patterns, and technology. This allows researchers to evaluate the potential impact of different transportation systems and make informed decisions about the most sustainable options.
By incorporating these considerations into measurements of transport access, it is possible to provide a more comprehensive understanding of the environmental impact of transportation systems, and to support the development of sustainable transportation solutions that balance accessibility, environmental impact, and social and economic factors.
Is there a way to do this systematically, for instance, by changing the Cost Function in the transport accessibility (Hansen) equation? [ed. (not shown to ChatGPT) See Cui and Levinson for what I am thinking of here.]
Yes, one way to incorporate environmental factors into transport accessibility measurements is by modifying the cost function in the Hansen accessibility equation. The Hansen equation is a commonly used formula to calculate the accessibility of a transportation system, by considering the travel time and cost associated with different transportation modes.
By modifying the cost function in the Hansen equation, environmental factors such as emissions of greenhouse gases, energy consumption, and exposure to air and noise pollution can be taken into account when calculating accessibility. For example, a higher cost could be assigned to transportation modes with higher environmental impacts, such as private vehicles, and a lower cost to modes with lower impacts, such as public transportation or cycling.
This approach allows researchers to systematically incorporate environmental factors into transport accessibility measurements and provide a more comprehensive picture of the sustainability of transportation systems. The modified cost function can be tailored to the specific environmental and geographic context, allowing for a customized assessment of the environmental impact of different transportation systems.
It is important to note that this approach should be combined with other methods, such as scenario analysis and life cycle assessments, to provide a comprehensive understanding of the environmental impact of transportation systems.
That answer is good as far as it goes, but I did have to spell it out. If you prompt chatGPT enough, you get a decent answer … but it doesn’t yet come up with this on its own. It is a bit of a bullshitter, (in the technical sense of the term), as has been observed elsewhere. In any case, it’s not good with equations yet, so we have a little bit of running room on the technical side of things before we are made obsolete.

Research into what is politically important in decision making is difficult. I work at that intersection of politics and infra/services change and while there are thematic similarities, I have to say that context, temporal issues, personal interests (politicians, their staff and advisors), fashion (everyone wants x), mis/understanding and financial cycle intersections (DFI/budgets/stimulus/inflation) all cross-cut in a hyper-localised way. It is rarely the technical excellence of planning, or the "obvious" best solution but rather the match of project/investment outcome narrative to self-interest (which can be good, bad, other) that drives one thing past another.
