S.F. streets particularly mean for pedestrians

More than 800 people are hit by cars in San Francisco each year, making it one of the most dangerous cities in the state - and possibly the country - for pedestrians.

This is a city that last year was named the best walking city in the country by the American Podiatric Medical Association and Prevention magazine because of the many city agencies assisting in walking issues. Yet more than two pedestrians are hit each day on average, accounting for about a quarter of all injury crashes and, according to some reports, nearly half the city's traffic fatalities.

The streets of San Francisco are especially dangerous in December, when shorter daylight hours, holiday-swollen numbers of pedestrians and cars, increased alcohol use and winter weather lead to the highest number of pedestrian-vehicle accidents.

The problems aren't all in December, however. A series of daytime collisions last month showed just how dangerous the city's streets can be.

-- On Nov. 17, 65-year-old Nu Ha Dam was struck and killed by a UCSF shuttle bus at lunchtime while crossing Geary Street at Leavenworth, two blocks from her home.

-- On Sept. 2, a hit-and-run driver who was later arrested killed 70-year-old Joyce Lau as she was crossing Cole Street at Waller shortly before 8 a.m.

-- Later that same day, around 5 p.m., a 79-year-old woman whose identity has not been released sustained life-threatening injuries while trying to cross Bayshore Boulevard at Bacon Street.

Each of the victims was in a crosswalk when she was struck.

"Why isn't that seen as a priority public health problem?" asked Dr. Rajiv Bhatia, director of occupational and environmental health for the San Francisco Department of Public Health.

Transit problem

But the high number of pedestrian fatalities, both locally and nationally, is typically viewed as a transit, rather than a public health, problem.

"There's a federal goal for zero airplane fatalities and a federal goal for zero railroad fatalities," Bhatia said. "Yet we have these acceptable levels of people getting hit by cars and killed."

When ranking traffic fatalities per 100,000 residents - including people killed in cars as well as pedestrians - San Francisco fares worse than such far larger cities as New York, London, Hong Kong and Tokyo, according to a report released in August by the New York City Department of Transportation, using 2008 data.

While San Francisco obviously is a dangerous city to walk in, the city's size may skew the numbers. Since the city is relatively small - with fewer than 800,000 people - and has a large number of pedestrians, especially downtown, the number of people hit might appear high when based on per capita rate.

Inattentive drivers

The San Francisco Municipal Transportation Agency released a report in October that found that the actual number of fatalities has consistently declined over the years, although the city still has a higher percentage of such deaths than other major cities. Motorists who fail to yield and inattentive drivers are the primary causes of the accidents.

Pedestrian advocates say the 800 pedestrian collisions a year - a number that has held fairly steady in recent years - is far too many, no matter how it's calculated.

"You don't really need to know more than the number of people being hit," said Elizabeth Stampe, executive director of Walk San Francisco. "The absolute number in issues of health is what really matters."

While the health effects of traffic include pollution, noise, stress and higher rates of asthma hospitalizations, pedestrian injuries are a blunt measure of the human cost of driving.

The top 10 most dangerous parts of San Francisco for walkers are concentrated in the Financial District and the Tenderloin, South of Market and Bayview neighborhoods. While those 10 U.S. Census tracts are home to less than 4 percent of the city's population, they account for about 21 percent of pedestrian collisions, according to an analysis of the data.
