"What the local businesses asked for was traffic lights on the original pedestrian crossing," Wallen told the council.
"There was no actual problem in Greerton... somehow, you managed to turn the simple request on behalf of businesses and motorists into an expensive... safety issue about pedestrians."
People called out "hear, hear" in support of Wallen's submission.
The issue of the Greerton traffic safety improvements was discussed for two hours.
Councillor Terry Molloy said: "Nobody disagrees that we have problems in Greerton."
Councillor Bill Grainger asked acting general manager of infrastructure Martin Parkes why congestion was not given consideration at all during the inception of the project "and what steps are we prepared to take to try to improve this?"
Parkes said alleviating congestion was not part of goals his team were tasked with. He said Greerton's congestion issues could be the result of significant population growth in area.
When Parkes said the project was a success, in terms of meeting its outlined goals, members of the public gallery jeered with one man calling out "What world do you live in?"
When things became heated committee chairman Councillor Rick Curach asked Wallen, and members of the public gallery, to refrain from personal attacks on council staff.
The council agreed to engage consultants to investigate options for improving the situation, including moving the pedestrian crossing and exploring the idea of a pedestrian overpass or underpass.
