The city let data drive its decision making in the placing of 20 new red-light cameras that will be put up across the city this year.

The new locations were announced on Monday, bringing the total number of cameras in the city to 54.

Krista Tanaka, program manger of road safety and traffic investigations, said they initially looked for place s where there had been three or more angle collisions in a given year. They then expanded that list to any intersections with five or more angle collisions involving vehicles heading in the same direction over the last several years.

(...)Tanaka said cyclists are counted in the vehicle tallies, so any intersections where cyclists and cars collide at right angles would have been captured in their search.

She said while pedestrians would not have been captured in the same hunt, they also don’t see many pedestrian collisions where red-light running is the major factor.
