Nonresponse bias occurs when some respondents included in the sample do not respond. The key difference here is that the error comes from an absence of respondents instead of the collection of erroneous data.
The margin of error is usually calculated based on the number of responses. With a sample from a finite population and a small sampling fraction you can treat the population as infinite, but with a large sampling fraction (more than 10% of the population size, say) you need a finite population correction.
So margin of error doesn't account the non response bias.
The asnwer is
People who have longer travel times to work might have less time to respond to a survey. This would cause our estimate from the sample to be less than the true mean travel time to work. The bias due to nonresponse is not accounted for by the margin of error.
