Tykes who ride MTA buses will have designated stroller-only spaces across the entire fleet of nearly 6,000 carriages by the end of the year, officials announced Thursday. All future bus orders will include spots for open strollers, while others are presently being retrofitted at MTA bus depots. “Parents feel more comfortable — it’s become more normal and socially accepted for strollers to be on buses,” she said. Unfolded strollers can enter via wheelchair ramps or lifts attached to every bus. Avissar added that signs on buses marking the space for strollers have helped tamp down potential conflicts with other passengers.
