New TFL website

Reply with quote It seems Transport for London has redesigned

http://www.tfl.gov.uk/

I find this interesting (from their accessibility statement):
Quote:
Access Keys

Access Keys are keyboard shortcuts to common pages on a website. This website does not use Access Keys because evidence suggests that they interfere with the keyboard controls of many browsers and screen readers.


Another reason to consider whether accesskeys are dead
Reply with quote I think this is definitely an unfailed (i.e. successful) redesign:
  1. First thing which really stands out (in every sense) is how strong the a:focus styling is. I hadn't considered using such a strong change but it does make sense.
  2. Interestingly, their skip link comes after a link to their homepage. The link to the homepage is present even when you are at the homepage. The image in the link has a non-empty alt attribute even though the link also has text; this will result in the link being spoken as "Transport for London Logo Transport for London".

    I think it would be better if they used alt="" here and had the skip link before it.
  3. A hyperlinked image of two people taking a picture in front of Tower Bridge is using an alt attribute whose value exactly matches a regular text link which points to the same location ("Get where you want to be"). That's nice attention to detail.
  4. It doesn't respond particularly well to text resizing. In particular, the "Service updates" section on the homepage becomes mis-aligned.
  5. The <title> is unique to each page and is front-loaded. It uses a vertical bar (|) to separate the page title from the website name; both are present on all pages. Looks like someone's been reading blogs about best practise. Smile
  6. From the accessibility page:
    Transport for London wrote:
    Use a 'plain' layout

    Many browsers allow you to strip a web page of all layout and styling by turning off the website 'style sheets'. If your browser supports this setting you will most likely find it in the 'View' menu.
    The person who supplied this text is probably a non-IE user, then. So this is probably provided by the website developer and if so, their choice of browser goes some way to explain the all-CSS layout.

    Again, they seem to be very up-to-date as they provide instructions for users to get the most from their setup rather than duplicating functionality with widgets on the website.
  7. Uses conditional comments to provide styling to IE! The developers of this site must really keep track of best practise blogs.
  8. The lack of visible labels in the "Journey Planner" sidebar might make the form harder to interact with for voice-activation users?
  9. I'm in two minds about the standards compliance of the markup. The Maps page has 75 errors or 81 when against the Strict standard. These are mostly from using uppercase tags when the document type declaration is XHTML. However, since the Content-Type response header is text/html, browsers will process it as HTML and therefore be case-insensitive. There are also some unquoted attributes for which the same is true. So it will work fine, but it's not strictly correct.

    Would probably be a good idea to make all tags lowercase and quote all attributes to make the markup more consistent, easing maintenance.
  10. The semantics of the markup seem excellent overall. But I'm not sure about their use of <dl>. It seems they think <dd>s all apply to the <dt> at the same time (accumulative) which is probably not the case.

    When used for dictionary definitions, only one description logically applies to the term at the same time (alternative). Although HTML4 relaxed the use of <dl> for things other than dictionary definitions, it didn't say whether <dd>s are accumulative or alternative. So, I guess it's still alternative (zcorpan also thought this last time I talked to him about it).

    As such, having a navigation parent item as a <dt> which then has a navigation child item in each of several <dd>s probaby isn't quite correct. Only one of these child items is semantically linked with the parent item at a time which doesn't reflect the navigation structure. Also, it's arguable whether these child items are actually describing the parent.

    The use the same thing in several other places, where it also doesn't seem quite right. I think <p> and <ul> would be more appropriate for this, or perhaps a twin layer nested <ul>?
From a standards compliance and best practise standpoint, I'm pretty impressed with this. I wonder if they did user testing to see if the theory improved usability?

Reply with quote It is quite nice

As you said it doesn't resize too good and the light blue links look like they are missing contrast

Didn't see the A:focus. You're right that is very nice. Almost reminds me of keyboard controlled computer games

I wonder if they did the site in house?
Reply with quote Hi there,

We designed the site in collaboration with a company called Detica, the template design and coding was done in-house though.

Thanks for your feedback, both positive and negative - it's all valuable. We put the site through some thorough user testing prior to launch, including users with various visual and other disabilities. In fact, it was watching people trying to use the site with a keyboard that prompted us to implement the 'focus' styles.

Your point about the semantics of definition lists is very interesting. It hadn't occured to me before that when you have multiple <dl>'s it might be interpreted that only one of them actually applies to the preceding <dt>.

Hopefully (one day) HTML 5 will give us a few more tools and we won't have to 'bend' the meaning of things like definition lists to suit our purposes.

Incidentally, we also implemented alternate style sheets (hi-contrast and large-text), for browsers that support these (try 'View -> Page style' in Firefox).

Reply with quote I think the site needs real world testing...

I am not sure if <dl> for such a critical area of the site is appropriate as they may not be supported by older devices such as versions of JAWS.

Code:
<a href="/gettingaround/1123.aspx" class="left" title="Timetables"><img src="/assets/images/landscape/bus-stop-display.jpg" alt="Timetables" width="246" height="145" class="border" /></a>
        <div>
            <h1><a href="/gettingaround/1123.aspx">Timetables</a></h1>

This main picture and title would be annoying for screen reader users having to read the link again. I would remove the <a> from the picture and leave the alt attribute blank OR use only 1 <a> making the title and link clickable again with no alt text.

Again the title attribute simply servers to annoy.

Very good job overall... down to the way a PDF icon appears via CSS in the search results.

Reply with quote Hi Tim

Nice work! It most have been a massive project. Are you planning on turning it into a case study to talk about the learnings you've made etc ?
Reply with quote Overall, the design is very nice. I do rather miss the prominant links to the different modes of transport that used to be across the top. It's much harder to see where to go from the front page if you want to know about the tube for example.

And I find the structuring a bit odd and hard to follow compared with the previous "one main section per mode of transport". For example the sifferent categories under http://www.tfl.gov.uk/... are different types of categorisations (eg some are modes of transport, but not all modes are present).

The URL scheme could probably be improved somewhat, though presumably it's somewhat impared by the structure behind it...
Reply with quote Thanks Chaos,

we thought very hard before switching to a task focussed IA from the old 'mode'-focussed one. The user testing, stats analysis and other evidence repeatedly bore out that, for most people, a task focussed site structure would help them find information more quickly - and the general feedback post-lauch seems to confirm this.

A failing of the old 'modal' structure was that it encouraged repetition - every modal section (Tube, buses, rail etc) would contain slightly different versions of the same content - a sure sign that something is wrong with the structure.

The transport-modal perspective is obviously what some people want though, which is why we've provided 'modal' landing pages available from the homepage.

Fransgaard - we have no plans currently to produce a case-study (no time, unfortunately!) - but did you have anywhere specific in mind where such a study would be published or made available?
