It’s not so much a phenomenon, as it is the fact that the LIRR right of way in those particular neighborhoods doesn’t align with major roads, which causes them to be inconvenient. Furthermore, the passengers that utilize the nearby Q12/Q13/Q15/Q28/Q31/Q76 aren’t the people who regularly use the LIRR for a multitude of reasons. Demographic travel patterns for those who take the train and/or NYCT buses is distinct to those who use the LIRR in the same neighborhoods. The people getting off the Q12/Q13 at say, Northern Boulevard & 192nd Street (Near the Auburndale LIRR Station) originate from the Flushing–Main Street Station, compared to Midtown Manhattan for the people getting off the LIRR at Auburndale Station.
