Council is expected to take a final vote next week on legislation that would permit about 20 cameras at intersections throughout the city. Under state law, the measure would die on July 15, 2017, unless the Legislature and council reauthorize it.

Pittsburgh police couldn’t provide information about which intersections in the city are most dangerous.

Council members cited traffic safety, ticket revenue and the “sunset” provision allowing for the measure to end as reasons for considering the program.

“What raised my comfort level enough to vote on it is there is a sunset provision,” Councilman Bruce Kraus said, adding that the city can use new revenue for traffic safety enhancements. “We can try it for two years. If it doesn’t work, council doesn’t have to renew it.”
