Mansfield Lane Traffic lights

Could something be done regarding the length of time the lights turn green, for traffic entering Barrett Road from Mansfield lane?

The lights do not stay green long enough, with maybe only 2 or 3 cars getting out at a time. Even less vehicles if its a bus or having to turn right and other cars are going straight across the junction.

It's also been made worse, with more cars using this junction since the restriction on using White Horse Lane through Trowse to enter the city a peak times.

Check the junction at peak times to get a true reflection of the problem. This has been like this for years now.
