Transportation Research Board | Main Meta Description

This is the Transportation Research Board Home page Test Results Mobile Usability: 50/100

Quick overview:
Size content to viewport
The page content is too wide for the viewport, forcing the user to scroll horizontally. Size the page content to the viewport to provide a better user experience.
The page content is 1,363 CSS pixels wide, but the viewport is only 980 CSS pixels wide. The following elements fall outside the viewport:
The element <a href="/Publications/…ewsletter.aspx" class="topHeader2014">E-NEWSLETTER</a> falls outside the viewport.
Use legible font sizes
The following text on your page renders in a way that may be difficult for some of your visitors to read. Use legible font sizes to provide a better user experience.
The following text fragments have a small font size. Increase the font size to make them more legible.
E-NEWSLETTER and 6 others render only 5 pixels tall (13 CSS pixels).
Configure the viewport
Your page does not have a viewport specified. This causes mobile devices to render your page as it would appear on a desktop browser, scaling it down to fit on a mobile screen. Configure a viewport to allow your page to render properly on all devices.
Size tap targets appropriately
Some of the links/buttons on your webpage may be too small for a user to easily tap on a touchscreen. Consider making these tap targets larger to provide a better user experience.
The following tap targets are close to other nearby tap targets and may need additional spacing around them.
The tap target <a href="/Publications/…ewsletter.aspx" class="topHeader2014">E-NEWSLETTER</a> and 1 others are close to other tap targets.

Quick overview:
Eliminate render-blocking JavaScript and CSS in above-the-fold content
Your page has 17 blocking script resources and 4 blocking CSS resources. This causes a delay in rendering your page.
Remove render-blocking JavaScript:
Use asynchronous versions of the following scripts:
Optimize CSS Delivery of the following:
Optimize images
Properly formatting and compressing images can save many bytes of data.
Optimize the following images to reduce their size by 239.3KiB (77% reduction).
Compressing could save 26.9KiB (98% reduction).
Reduce server response time
Leverage browser caching
Setting an expiry date or a maximum age in the HTTP headers for static resources instructs the browser to load previously downloaded resources from local disk rather than over the network.
Leverage browser caching for the following cacheable resources: (expiration not specified)
Prioritize visible content
Your page requires additional network round trips to render the above-the-fold content. For best performance, reduce the amount of HTML needed to render above-the-fold content.
162.7KiB of the HTML response was required to render the above-the-fold content. This requires 4 network round-trips. Prioritize the above-the-fold content so that it can be rendered with only the first 2 round-trips' worth of HTML.
None of the final above-the-fold content could be rendered with the HTML delivered within 2 round-trips.
Enable compression
Compressing resources with gzip or deflate can reduce the number of bytes sent over the network.
Enable compression for the following resources to reduce their transfer size by 92.9KiB (55% reduction).
Compressing could save 89.3KiB (54% reduction).
Avoid landing page redirects
Your page has 2 redirects. Redirects introduce additional delays before the page can be loaded.
Avoid landing page redirects for the following chain of redirected URLs.
Minify JavaScript
Compacting JavaScript code can save many bytes of data and speed up downloading, parsing, and execution time.
Minify JavaScript for the following resources to reduce their size by 17.5KiB (37% reduction).
Minifying could save 13.9KiB (41% reduction) after compression.
Minify HTML
Compacting HTML code, including any inline JavaScript and CSS contained in it, can save many bytes of data and speed up download and parse times.
Minify HTML for the following resources to reduce their size by 16.4KiB (11% reduction).
Minifying could save 16.4KiB (11% reduction).
Minify CSS
Compacting CSS code can save many bytes of data and speed up download and parse times.
Minify CSS for the following resources to reduce their size by 2KiB (16% reduction).
Minifying could save 1.4KiB (18% reduction) after compression.
