On 30/6/15 at 5.00pm. noticed that green light phasing at Matai St / Staven Rd intersection for southbound traffic heading south on on Straven Road is not lasting long enough. Traffic building up all the way back up to Fendalton Rd. Matai street westbound traffic getting a much longer green light phasing. This set of lights is not normally a problem. But was very noticeable tonight.
