Björn Gohla<p>If we assemble passenger transport modes into a hierarchy, ordered by speed and distance covered (e.g., air travel at the top, long distance high speed trains below, then regional trains, urban rail, subway, tram, cycling, walking), then the rule should be that in any multimodal trip we should only need to ascend, then descend the hierarchy.</p><p>Having to walk between train stations to transfer, or not having high speed rail directly at the airport violates this rule.</p><p><a href="https://mathstodon.xyz/tags/transport" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>transport</span></a> <a href="https://mathstodon.xyz/tags/travel" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>travel</span></a> <a href="https://mathstodon.xyz/tags/trains" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>trains</span></a> <a href="https://mathstodon.xyz/tags/planes" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>planes</span></a> <a href="https://mathstodon.xyz/tags/idleThoughts" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#<span>idleThoughts</span></a></p>
