Bright yellow flowers mark the crosswalk where Mariah Danforth- Moore was killed last fall.
Her family said it was her favorite color and a reflection of her cheerful personality.
"Her smile so outgoing,... got along with everybody, she didn't have any enemies," said her mother, Lisa Moore.
Though no longer married, Stephen Danforth and Lisa Moore share the heartache over losing their only daughter.
On November 20th 2011, Danforth- Moore died crossing Kamehameha Highway near Hawaii Pacific University's windward campus.
The 19-year-old attended the school, where she blossomed as a psychology student.
Danforth-Moore's grandparents, siblings and extended family, who flew in from the mainland, grieved at the crash site Saturday afternoon.
"It's unbearable it doesn't feel like it's going to get any better," said Moore.
Shortly before Danforth-Moore's death the state installed a button activated voice alert, warning pedestrians to cross with caution.
It also added solar flashing lights signaling to drivers that someone is crossing.
Danforth, who moved to Oahu from Wisconsin to be closer to his daughter, says the safety features provide a false sense of security.
"It's still inadequate. It's still unsafe and if nothings done about it's going to happen again," said Danforth.
The young woman's parents and her relatives attended a memorial service Saturday afternoon on the HPU where a tree was planted in honor of Mariah's life
Her parents want the state to build a bridge over the highway.
They are hoping others will support their cause, so no other family suffers their pain.
What I really want to happen is for the whole community, this whole area to fix intersections not just this intersection but every intersection," said Danforth.
Danforth-Moore's parents are scattering their daughter's ashes in a private memorial tomorrow.
The driver involved in the crash was released pending further investigation.
Honolulu police said he failed to render aid.
