As an academic studying international law, climate change and human rights, Ladan Mehranvar is accustomed to navigating complex issues. But she said nothing prepared her for the challenge of getting her daughter, who has a seizure disorder, onto a New York City school bus.

“Sometimes I just sit and cry,” she said. “I feel like I have no control over it.”

Mehranvar said her daughter’s bus schedule is inconsistent. And the routes are inefficient, stretching from 90 minutes to nearly two hours each way from her Upper West Side home to a special education program in Queens. Meanwhile, the longer her daughter is stuck on the bus, the more vulnerable she is to seizures.

“It’s just excruciating,” Mehranvar said.
