截至 2026 年 4 月 24 日美国司法部《美国残疾人法案》(ADA)第二章规则的截止日期,许多美国城市的数字服务仍存在可访问性障碍。AccessLumens 分析了 158 个美国大型市政府网站,发现尽管平均可访问性得分为 93/100,但仍有 42% 的网站存在关键性障碍。 这些障碍(如无法使用的按钮、菜单或链接)阻碍了依赖辅助技术的居民获取基本的政府服务。与商业网站不同,城市门户网站是居民必须使用的平台;一旦这些平台出现故障,居民将无法缴纳税款、申请许可证或参与地方政府事务。 AccessLumens 强调,较高的平均得分可能会掩盖那些将用户拒之门外的“致命”缺陷。鉴于新的法律要求服务人口超过 5 万的司法管辖区必须符合 WCAG 2.1 AA 级标准,该研究指出,各城市亟需优先修复这些关键且可检测的可访问性漏洞,以确保公共服务的公平获取。

最近的一篇“Show HN”帖子指出,92% 的美国城市网站未能达到《美国残疾人法案》(ADA)的无障碍标准。该帖在 Hacker News 用户中引发了关于政府门户网站导航长期存在困难的讨论。 评论者指出,这些网站的设计往往十分糟糕,导致残障用户几乎无法获取重要信息或完成表格填写。一位用户认为,联邦政府应强制所有“.gov”域名使用标准化的设计系统(如美国网络设计系统 USWDS),以确保各方能够保持一致的无障碍访问体验。

The ADA Title II deadline passed on April 24, 2026. 42% of city sites still have a critical accessibility barrier.

Under the Department of Justice’s 2024 ADA Title II rule, state and local governments serving 50,000 or more residents had until April 24, 2026 to make their web content conform to WCAG 2.1 Level AA. We scanned 221 of the largest US city governments after that deadline — homepage and a resident service page each — to ask a simple question: did they make it?

The nuance that matters: city sites are not catastrophically broken. The average score across the 158 scored cities was 93 out of 100. But 42% still carried at least one critical barrier after the compliance deadline — a control a resident cannot operate: a button a screen reader announces as nothing, a menu a keyboard user can never reach, a link with no discernible purpose. A good score and a locked-out resident are not mutually exclusive.

And unlike a retailer, a city is not optional. If its permit form, tax portal, or council page is unusable with assistive technology, there is no competitor to switch to — and, post-deadline, there is a legal obligation it is now missing.

Methodology

We selected the largest US city governments by population and attempted 221 of them; our sample covers cities of roughly 100,000+ residents, the upper portion of the 50,000+ cohort covered by the April 24, 2026 ADA Title II web deadline. Each city was scanned on up to two pages — its homepage and one resident service-flow page (online payments, permits, or contact) — using the AccessLumens scanning engine (SWBS-1.3 scoring) with identical configuration for every page of every city, including scripted keyboard testing (focus traps, focus visibility, reachability, skip links). 51 cities (23%) could not be scanned because bot-protection challenges blocked a real headless browser; those are reported as a finding but excluded from the scored statistics, leaving 158 scored cities. We enforced strict robots.txt compliance — pages a site disallows were not scanned. CMS vendors were fingerprinted from page markup and response headers; vendors with fewer than eight cities are excluded from the vendor comparison. ADA Title II requires WCAG 2.1 Level AA; our engine tests WCAG 2.2 AA, a superset, so a city failing here also fails 2.1 AA. Headline failure statistics count automatically detectable WCAG violations; best-practice advisories and manual-review items are excluded. A city’s score is the mean of its scanned page scores. Individual cities are not named — the purpose of this study is to describe the state of the sector, not to single out governments. Scores use our SWBS model; this is a diagnostic snapshot, not a legal conformance determination (see our disclaimer).
