Lagging Left Turns Would Improve Crosswalk Safety at Complex Intersections
When left turn signals are installed, they typically turn green at the start of a street's green phase. However, simply reversing that order and putting left turns at the end of the green phase could reduce conflicts between turning cars and people walking in the same direction. As left turn signals have been installed at more Chicago intersections, motorists often are caught completing their left turns just as through traffic – and pedestrians – get a green light. The resulting conflict isn't safe for anyone.

Mapping How Far You Can Bike Without Breaking a Sweat
Any bicyclist knows that maps can be quite deceiving at first glance. The first time I tried to traverse San Francisco on a bicycle, I foolishly set out from the bike-rental shop on Fisherman's Wharf with a basic street map, and decided that I'd avoid downtown traffic by heading south across the grid. While I was correct that the city's connected street grid offered many direct routes, I neglected to notice the huge ridge of Pacific Heights looming directly ahead, or the numerous full-stop intersections along the way that would further sap my momentum.
