A woman in West Sacramento is in critical condition after, police say, she was struck Friday night by a passing vehicle on West Capitol Avenue.

The unidentified 40-year-old woman was walking down West Capitol near Jefferson Boulevard around 10:30 at night when she was hit in the roadway.

The incident is just one of several that have West Sacramento police taking notice of a surge of accidents in 2016, many of which, have resulted in deaths.

"We have seen a definite increase in fatal accidents in the area," said West Sacramento Police Sgt. Roger Kinney.

According to Kinney, nine people have been killed in accidents in the city so far in 2016. Of those, five were pedestrians, two were bicyclists and two were in vehicles. And most have happened along the miles-long West Capitol Avenue.

On August 28, a 92-year-old man was riding his bicycle near Jefferson Boulevard when he was struck by a vehicle. And just three days later, UC Davis professor Kentaro Inoue, 47, was hit by a garbage truck and killed while riding his bike near Poplar Avenue.

"It's not just one spot, it's a problem area up and down West Capitol Avenue," Kinney said.

Kinney added that one man was fatally hit by a charter bus Oct. 8 in the 4200 block of West Capitol Avenue when he was walking his bicycle across the street.

Meanwhile, the driver involved in Friday's collision has been cooperative, and police are investigating what led up to the accident.
