How Bad is Traffic in San Francisco?

How Bad is Traffic in San Francisco?

Residents of San Francisco are no strangers to traffic jams and long commutes. According to 2020 Census data , more than 870,000 people call the city home. Including the surrounding Bay Area, the number of residents would exceed 7 million. At this time, drivers often find themselves stuck in traffic jams or because of accidents. This has some people wondering, "How bad is traffic in San Francisco?" For residents and tourists, knowing the answer may help solve traffic congestion and keep roads safe.

Traffic in the Bay Area

While Los Angeles is consistently ranked as the most congested city in the U.S., the Bay Area is "not far behind." According to Bay Area traffic statistics , the subway holds a place in INRIX's global congestion rankings. The report also found that in 2019, drivers typically waited 97 hours in traffic, indirectly costing the city about $3 billion.

What's more, there are other factors that contribute to increased traffic congestion in addition to the large population. For one thing, San Francisco's dense infrastructure doesn't allow cars and buses to navigate city streets and highways with ease.

On the other hand, poor overall road quality can also cause congestion. San Francisco has most of the poorly maintained roads in the United States. An analysis by Teletrac found that 71 percent of roads in the Bay Area are in poor condition. Ongoing construction projects to restore roads and poor road conditions have made traffic jams worse.

When San Francisco traffic is at its worst

Several models have emerged to help drivers reduce the chance of a Bay Area crash when traffic is heavy . An analysis of traffic patterns by the city of San Francisco found that rush hour traffic hours are more prone to accidents from 7 a.m. to 9 a.m. and 4:30 p.m. to 6:30 p.m. Monday through Friday. Given that this is the traditional "rush hour" when most people commute to work or home, this is not surprising.

However, people on the road need to be extra careful during these times of the day due to the increase in the number of cars. While biking may be a healthier way to commute than driving, San Francisco's bicycle accident statistics suggest that it carries its own risks. According to UC Berkeley's Traffic Injury Mapping System (TIMS), San Francisco has the second-highest rate of bicycle-related deaths and injuries in the state, with 46 people killed or injured.


旧金山交通状况有多糟糕?

旧金山的居民对交通拥堵和漫长的通勤时间并不陌生。根据2020 年人口普查数据,超过 870,000 人以这座城市为家。如果将周围的湾区包括在内,那么居民人数将超过 700 万。这时,驾驶员经常发现自己陷入了交通拥堵或因事故的困境。这使一些人想知道,“旧金山的交通有多糟糕?” 对于居民和游客来说,知道这个答案可能有助于解决交通拥堵和保持道路安全。

湾区交通状况

虽然洛杉矶一直被评为美国交通拥堵最严重的城市,但湾区也“不甘落后”。根据湾区交通统计数据,地铁在 INRIX 的全球拥堵排名中占有一席之地。报告还发现,在2019 一年中,司机在交通中通常要等待 97 小时,间接导致该市损失了约 30 亿美元。

更重要的是,除了人口众多之外,还有其他导致交通拥堵加剧的因素。一方面,旧金山密集的基础设施不允许汽车和公共汽车轻松地在城市街道和高速公路上行驶。

另一方面,道路整体质量差也会造成拥堵。旧金山拥有美国大部分维护较差的道路 。Teletrac 的一项分析发现,湾区 71% 的道路状况非常糟糕。正在进行的修复道路的建设项目以及由恶劣的道路条件让本就堵塞的交通雪上加霜。

当旧金山交通最糟糕的时候

现在已经出现了一些模式来帮助司机减少在交通拥堵严重时发生湾区车祸的机会。旧金山市对交通模式的分析发现,交通高峰期更容易发生事故的时间是周一至周五早上 7 点到 9 点,以及下午 4:30 到下午 6:30 。鉴于这是大多数人在路上上班或回家的传统“高峰时段”,所以这并不奇怪。

然而,在一天中的这些时间里,由于汽车数量的增加,路上的人需要格外小心。虽然骑自行车可能是比开车更健康的通勤方式,但旧金山的自行车事故统计数据表明,它有其单独的风险。根据加州大学伯克利分校的交通伤害测绘系统 (TIMS),旧金山的自行车相关死亡和受伤发生率在该州排名第二,有 46 人死亡或受伤。
