On January 2, two people suffered life-threatening injuries in separate traffic collisions. Both victims were transported to a hospital, police said Friday.

A pedestrian, identified only as a woman, was hit by a 41-year-old man near the City College of San Francisco, and San Francisco Fire Department Station 15, in the Ingleside neighborhood at Ocean and Harold avenues. Police said the driver made contact with the pedestrian, who suffered life-threatening injuries from the encounter. The collision occurred at 7:37 a.m. and remains a pending investigation.

Then, at 6:01 p.m. on the same day, an 18-year-old man who was riding a bicycle was struck by a driver while walking at 43rd Avenue and Fulton Street near Golden Gate Park, causing life-threatening injuries. The driver remained on scene and cooperated with the investigation. No arrests were made in both cases.

Neither intersection is identified as a high-injury corridor under the city's Vision Zero plan, which aims to eliminate traffic fatalities by 2024. Last year, 29 people were killed on San Francisco streets, including 18 pedestrians and one bicyclist. The city is currently not meeting its Vision Zero target, according to Vision Zero's website.
