The phrase "walks over time" is grammatically correct and can be used in written English.
It is typically used to describe a gradual process or change that occurs over a period of time. Example: "As he walks over time, he becomes stronger and more confident, leaving his shy and insecure self behind."
These changes included an approximately 9-fold increase in speed (flying and walking) over time (Table 2A).
This suggests a general habituation to cross-slope walking over time.
7 The increased proportion of older Americans with physical limitations (stooping, lifting, reaching, grasping and walking) over time may also partly explain these findings.
Consistent with a biased random walk, over time the axon will develop ventrally in response to UNC-6, even though at a discrete time UNC-40 localization and outgrowth can be observed anterior or posterior.
Furthermore, improvement in walking ability over time or maintenance of the ability to walk was observed in 29% of residents, which reduced the risk of hospitalization for UTI by 53%.
Multiple inflammatory markers (IL-6, TNF-α, C-reactive protein [CRP]) predicted mobility limitations, specifically the inability to climb 20 steps or walk one-quarter mile (Penninx et al 2004), and women with elevated IL-6 demonstrated declines in walking speed over time and disability in activities of daily living (Ferrucci et al 2002).
We find that the average number of unique nodes visited in a single walk increases over time, indicating an increase in the network's navigability.
The ability to track walking speed over time is a huge boon to clinical research, as a growing body of evidence suggests it's a great indicator for helping to predict health issues, and the ability to identify changes in stride length, too, can help better understand certain conditions, like Parkinson's.
I suppose one answer is that, as the economy allows new businesses and homes to be built in and around the bad stuff, we can gradually make the newer land uses better and more "walk-ready" over time, so that the place can function better for pedestrians when the good stuff reaches critical mass.
