Traffic intelligence network INRIX has seen congestion double on some of London’s key routes in the wake of Olympic lane restrictions implemented by authorities in the UK.

INRIX noted the congestion increase on the A12, A13 and A40 from an average of 36 minutes congestion to 80 minutes, taking place on the morning of Monday 23 July 2012.

According to INRIX, this increase in congestion is due to the introduction of additional traffic management schemes related to the implementation of the Olympic Route Network.

INRIX traffic analyst Cat Kobylinski said that there were 35 minute delays along the A12 on Sunday 22 July 2012 due to the lane restriction now in place at the Lea Interchange.

"That is 30 minutes longer than a usual Sunday," Kobylinski added.

"However, this morning the delays were more severe. A lane closure on the A13 Newham Way caused two hour delays and traffic heading into town from the west had delays of almost 80 minutes from the M40 because of the lane restriction at A40 Hanger Lane."

An unsafe building affecting traffic approaching the Hanger Lane junction on the A40, in addition to the lane restrictions, has led to congestion being more than doubled on these key routes.

The journey time for motorist from the M40 at Denham in to the Westway has increased to twohours, with a similar time to travel between Dagenham and Aldgate on the A13, while an hour is required to travel on the A12 between Redbridge and Blackwall.
