Edmonton police handed out 2200 speeding tickets in a one-day blitz last Thursday. Do these campaigns actually make the streets safer or do they just serve to make drivers' pockets lighter?

The CBC's Scott Fralick spoke with international experts visiting Edmonton for the International Conference on Urban Traffic Safety. Most, like professor Ian Johnstone, who studies traffic injuries at Australia's Monash University, says speeding crackdowns are important to keeping roads safe, if they are well-publicized. 

"You actually change the climate around speeding and then there's no money."

This year, police wrote 700 more tickets during last week's speeding crackdown compared to a similar event last March.
