I am looking for the effect of hot climate on the behavior of transit use and public transportation ridership? and what is the human thermal comfort in outdoor spaces in a hot arid region?
I had some experiences in the desert and in pre desert areas but I don't consider exactly them as public transportation' issue.
I remember that the low percentage of umidity let the temperature much more affordable respect those I have to deal with in summer in my home town (north of Italy) where I found during the night around 30 Celsius degree with an umidity of 95/100%.
I'd like to be informed about the development of your research.
This is not an accademic point of view. Some 20 25 years ago I studied what is now called sub saharan Africa.
The arid region in Africa are scarcely populated. They tend to use rail if rail where it has been implemented for goods transport (ore) and when this is possible.
The populations are poor, so most of them can't afford public transit they mostly walk for short distances. Bicycles and scooters are the main competitors of public transit.
The traffic flows are very small, so some small capacity vehicules are used. for urban and interurban transport.
another observation : the red centerr in Australia (not a desert but an arid area)
population rdensity and very long distance don't allow for convenient roads to be buit.
conversely it is relatively easy to maintain dirt runway (very few rain). This lead to a situation where, for exemple, the doctors are flying to the population (the famous Roal Flying Doctor, base in Alice Spring.
