Denver Mayor Mike Johnston is trying new strategies to curb traffic fatalities on his city’s streets in a pilot program aimed at slowing down drivers who speed along major thoroughfares. Denver has recorded 27 traffic deaths so far this year, with the latest occurring last week on June 17. Last year, 83 people died, according to the city, despite officials launching the Vision Zero initiative several years ago, setting a goal of reaching zero traffic deaths by 2030. On Monday, Johnston announced the rollout of new approaches — initially along stretches of Federal Boulevard and Alameda Avenue — that include investing in more speed limit and speed feedback signs, expanded signal timing to give pedestrians extra moments to cross the street and more speed enforcement, such as ticketing. The city aims to cut the number of traffic fatalities by half over two years.
