Yes. Mostly, the literatuture looks at the manner in which mobility and sensory deficits, which inhibit automobile use, affect transportation choices. In the U.S. around 20 percent of seniors are limited in their transportation choices. See, here,
Anna I. Torres-Davis, “The need for improved transportation options for the elderly and the elder advocate’s role,” Journal of Poverty Law and Policy 42 (5&6) (2008): 281-291. This fits into a broader on "transportation disability". In my own work, this includes the manner in which public transit systems that do not accommodate persons with physical or sensory deficits can limit citizen interaction with the urban environment.
Good question, and nice to see the first response from my friend Tom Koch.
From another perspective, and assuming you literally mean age-specific attraction of traffic to specific zones, I'm sure you will want to consider the role of schools -- especially in the US there are huge resources used to transport children (elementary - middle school and high school) to very specific clusters of buildings -- schools. These are significant traffic generators, and both auto and buses are involved. An important valid age related factor here for mode choice would seem to be possession of a driver's license (16 +).
There are also certain land use attractors that are likely to have some age (and possibly gender and socioeconomic biases). I'm thinking of concerts, sports event, entertainment districts, and so on.
Finally, more along the line of Tom's response -- if one has a disability that prevents driving, and if public transit (Americans with Disabilities Act [ADA] is important here) does its job, there are probably pockets of accessible places that are reachable differentially by varying sub groups of the population. I will not presume that this is causally linked with age, but there could well be some correlation / interaction effects (say age vs visual impairment). In certain cases the train and bus is an option, whereas the car is not.
