Safer Intersection Design Using Crossing Islands

Safer Intersection Design Using Crossing Islands

by Peter G. Furth and Milad Tahmasebi At unsignalized intersections, crossing islands make it so much safer and easier for pedestrians to cross the street. They can also deliver many other benefits, including slowing through traffic, slowing turning traffic, and...

Connectivity of Low-Stress Bicycle Networks

If you don't mind riding on high-stress roads, you can go anywhere on your bike. But for those who aren't willing to use roads with high traffic stress, it may be that you just can't get from here to there. When high-traffic-stress roads are excluded, the remaining...

Level of Traffic Stress

Level of Traffic Stress

Latest LTS criteria (v. 2, June, 2017) for classifying road segments by level of traffic stress are found here. Original (2012) criteria for classifying road segments by level of traffic stress are found here.   The chief deterrent to riding a bike in the U.S. is the...

Self-organizing Traffic Signals

Self-organizing Traffic Signals

These net­works could create safer and more effi­cient traffic pat­terns than existing sys­tems that cur­rently either use sen­sors to detect traffic or rely on coor­di­nated and timed loops—which can be dif­fi­cult to pro­gram and make travel less effi­cient for public transit and pedestrians.
