4. Performance of the transport networks<br />
with a sharp 13 per cent <strong>in</strong>crease <strong>in</strong> average traffic delay, provid<strong>in</strong>g a marked<br />
contrast to the historic trend.<br />
• The historic stability <strong>in</strong> these trends is thought to reflect a comb<strong>in</strong>ation of<br />
fall<strong>in</strong>g traffic levels and much improved network management, albeit that<br />
effective network capacity for general traffic cont<strong>in</strong>ued to be reallocated to<br />
other MTS priorities. The recent change <strong>in</strong> trend is thought to reflect <strong>in</strong>creas<strong>in</strong>g<br />
traffic levels, coupled with temporary disruption from the unprecedented<br />
construction boom affect<strong>in</strong>g <strong>London</strong>’s roads. Clearly, this change <strong>in</strong> road<br />
network conditions will need to be a focus for future plann<strong>in</strong>g, especially given<br />
the expected cont<strong>in</strong>ued rapid growth <strong>in</strong> <strong>London</strong>’s population and the <strong>in</strong>creas<strong>in</strong>g<br />
requirement for improvements to the wider urban realm <strong>in</strong> <strong>London</strong>.<br />
• Journey time reliability on the TfL road network (the TLRN) – has largely<br />
reta<strong>in</strong>ed its historic stability <strong>in</strong> the most recent year, stand<strong>in</strong>g at a value of 88<br />
per cent <strong>in</strong> 2014/15, aga<strong>in</strong>st an average over the available time series of 89 per<br />
cent (of road journeys completed ‘on time’). This reflects a strong focus by TfL<br />
to m<strong>in</strong>imise the impact of temporary disruptions and works, and to actively<br />
manage traffic to optimise overall network conditions.<br />
