Accessibility Statement
BusBusiness recognises the importance of providing a Web site that can be used in a variety of ways which do not depend on a single sense, ability, or technology. Building a Web site which is usable, desirable and accessible for all user groups, including the disabled, is our ongoing commitment.
Standards Compliance
The Bus Business Web site conforms to W3C's Web Content Accessibility Guidelines 1.0, level Triple-A.
Below there's a list of critical requirements, which alone cover nearly 40% of highlighted by W3C accessibility problems (according to DRC report). These has been given extra attention and highest priority during expert evaluation.
- Provide a text equivalent for every non-text element
- Ensure that foreground and background colour combinations provide sufficient contrast when viewed by someone having colour deficits or when viewed on a black and white screen
- Ensure that pages are usable when scripts, applets, or other programmatic objects are turned off or not supported. If this is not possible, provide equivalent information on an alternative accessible page
- Until user agents allow users to freeze moving content, avoid movement in pages
- Until user agents allow users to turn off spawned windows, do not cause pop-ups or other windows to appear and do not change the current window without informing the use
- Divide large blocks of information into more manageable groups where natural and appropriate
- Clearly identify the target of each link
- Use the clearest and simplest language appropriate for a site's content

Semantic markup
Structured, semantic markup is used to represent document structure. H1 tags are used for main titles, H2 tags for subtitles, and so on.
Cascading style sheets are used for visual layout, and Javascript is used to enhance usability and for decorative purposes, however pages are still fully accessible if these technologies are ignored or unsupported.
Images
Descriptive and meaningful text equivalents are provided for all content images, graphical buttons, symbols and objects. Images are not used to represent text, all headings are styled with the help of CSS and can be resized to suit users needs.
Colours
Web site design has been tested against color contrast to ensure that all information is still clear.
Most of the text is written as black on white and is perfectly contrasting. Red color (#AB231D) is used for headings and links. Red on white combination passes color visibility test successfully:
- The difference in brightness is sufficient. The threshold is 125, and the result of the foreground and background colours is 180.
- The difference in colour is sufficient. The threshold is 500, and the result of the foreground and background colours is 530.
Font sizes
Relative units have been used in markup language and CSS, therefore Web site layout accommodates resizing text even in Internet Explorer for Windows.
Tables
Tables are not used for layout. For data tables row and column headers are identified.
Forms
All forms follow a logical Tab sequence. Each form field has a descriptive label, implicitly associated with it either through markup or positioning on the page.
Links
Link phrases are meaningful and descriptive. Whenever possible, links are written to make sense out of context.
Language Clarity
Web site content is written in complete, grammatical sentences. Links, headings and navigational elements are labeled in meaningful and descriptive way.
Introductory text on the homepage has been checked with readability test (Gunning Fog, Flesch Reading Ease, and Flesch-Kincaid reading level algorithms) and provides satisfactory results.
- Gunning Fog Index - 11.53
Gunning-Fog index is a rough measure of how many years of schooling it would take someone to understand the content.
Typical Fog Index Scores:
Score Resources 6 TV guides, The Bible, Mark Twain 8 Reader's Digest 8-10 Most popular novels 10 Time, Newsweek 11 Wall Street Journal 14 The Times, The Guardian 15-20 Academic papers Over 20 Only government sites can get away with this, because you can't ignore them Over 30 The government is covering something up
- Flesch Reading Ease - 61.43
The index number rates the text on a 100-point scale. The higher the score, the easier it is to understand the document. Authors are encouraged to aim for a score of approximately 60 to 70.
- Flesch-Kincaid Grade - 8.21
Like the Gunning-Fog index, it is a rough measure of how many years of schooling it would take someone to understand the content.
