A reliable and effective strategic road network
Average peak time travel speeds on strategic routes
The RLTP target is to reduce severe congestion on strategic roads and the 2025 outcome is an increase in average speed of 10%.
Unfortunately this monitoring series has been discontinued so there is no annual data for 2019/20. The average monthly travel speed for vehicles on each route is shown in the table below. The overall average speed for AM inbound and PM outbound traffic is 35 and 39 kph respectively for 2017-2019.
The figure below shows the average travel predictability over the period 2014-2019 for six strategic routes using a three year rolling average. Several changes have been made to the way travel time traffic speed is monitored. Travel speed variability is now defined as predictability.
In 2019 there was 63% inbound AM peak predictability and 64% outbound PM predictability. Initial findings show that traffic congestion is not improving
The vehicle travel data is collected using GPS data from commercial vehicles during March each year.
