Transit Delivery Atlas

Independent analysis · Unofficial

Accessibility

Accessibility is a release requirement.

The atlas targets WCAG 2.2 Level AA and is being evaluated against applicable Revised Section 508 web requirements.

Standards target

Revised Section 508 incorporates WCAG 2.0 Level A and AA for web content. WCAG 2.2 AA adds newer success criteria, but does not by itself prove full 508 conformance. Scoping, functional performance, support, and documentation still matter.

This independent site is not represented as a federal system or as certified. Section 508 readiness is relevant because California Government Code §7405 applies Section 508 accessibility requirements to state governmental entities’ information technology work and procurement.

Current evaluation status

Completed on the current development build

  • Static: lint, canonical-data validation, and rendered HTML assertions.
  • Structure: checks for page language, titles, skip navigation, main regions, layer labels, and the result-count live region.
  • Automated review: representative-route scans plus programmatic reflow, focus-order, and reduced-motion spot checks.

Pending before any conformance claim

  • Keyboard: complete user-flow review in current Chrome, Firefox, and Safari.
  • Assistive technology: VoiceOver and NVDA or JAWS review of the explorer, directive detail, method, and download flows.
  • Low vision: full 200% and 400% zoom, text-spacing, forced-colors, and narrow-width review across every route.
  • Human evaluation: testing with disabled users and a documented decision about the inaccessible external source PDF.

Automated checks are quality controls, not certification. Until the pending reviews are complete and exceptions are documented, the project does not claim WCAG or Section 508 conformance. A future Accessibility Conformance Report would need to name the exact release, evaluator, method, environment, and exceptions.

Known external limitation

The signed executive order is hosted externally as a scanned, untagged PDF outside this repository and the site evaluation scope. The atlas provides semantic HTML summaries, short reviewed excerpts, and page locators to reduce that barrier, but those are not a complete alternative version and cannot remediate the authoritative source file.
