Transport Advice Portal
TAP is a paper-free technical library devised to help you find the up-to-date documents you need when planning, designing and operating road networks in the UK. The portal acts as a one-stop-shop depository of web links to core documents produced by a range of organisations. It will help you find specific documents you already know about but will also direct you to helpful information you may not previously been aware of.
