The City of Ottawa has installed digital signs showing drivers how fast they're travelling on Bronson Avenue near Carleton University, a week after city staff launched a safety review of the road.

Last month Carleton University student Krista Johnson, 27, was struck by a car and killed on Bronson just south of Holmwood Avenue.

Though it is not known if speed was a factor in the collision, people who live near Bronson have suggested the speed of traffic on the road poses a safety risk.

The current speed limit for the stretch of road where Johnson was struck is 60 kilometres per hour.

While much of Bronson is 70 km/h, on Wednesday the digital signs were regularly recording speeds greater than the posted limit.

"I am concerned about the speed on Bronson, it's basically a highway in the middle of the city," said Katherine Arnup, after she walked across Bronson in front of Carleton University.

Avg. speed more than 20km/h above limit

Arnup also questioned how effective the signs would be at reducing speeds.

"The digital signs were parked off to the right shoulder of the road at a point where Bronson is six lanes wide, and in a wave of traffic it's not obvious which car the sign is measuring. The digital displays were also difficult to read with the glare of the sun," she said.

Further north near the spot where Johnson was killed, a sign informs drivers that there is "zero tolerance for speeding."

Coun. Marianne Wilkinson said studies showed the average speed is 84 km/h on Bronson near the university, instead of the posted 60 km/h.

The city's transportation committee last week asked staff to conduct a "comprehensive" review of safety on Bronson and report back to the committee in March 2013.

The sign is one part of the review, according to Wilkinson, who is also the chairwoman of the city's transportation committee. She said there was also a police blitz last week along Bronson.

Coun. David Chernushenko had asked the committee to consider lowering speed limits between Holmwood and Brewer Way to 50 km/h. He also said he would ask police to boost their enforcement of the current speed limit on Bronson until the study is completed.
