<p>The criterion for the spacing of emergency areas for the initial dynamic hard shoulder
running pilot scheme on the M42 was set at approximately 500 metres. Based on more
operational insight and further performance data, the spacing was progressively increased
to a maximum of 1000 metres on all other dynamic hard shoulder running schemes and
then to 2500 metres on existing All Lane Running schemes.</p><p>Highways England undertook
a comprehensive review of smart motorways and found no consistent correlation between
the number of live lane stops and the spacing of emergency areas. Nevertheless, Highways
England understand motorists want to feel safe and therefore are making a number of
changes to the design of emergency areas.</p><p>On new schemes, starting construction
from 2020 onwards, the maximum spacing of emergency areas will be reduced to 1600
metres (1 mile). Highways England are also enhancing the visibility of emergency areas
on all new and existing smart motorways by installing orange surfacing and improved,
more frequent signs. These changes are designed to help drivers feel more confident
that they can find a safe place to stop in an emergency.</p><p><strong> </strong></p><p><strong>
