intersections

A short BicycleDutch episode showing how Dutch protected intersections continue cycle paths through the junction without needing extra street width.

A short research demo of Autonomous Intersection Management, a protocol in which self-driving cars reserve slots through an intersection instead of obeying signals or stop signs. It uses UT Austin's autonomous vehicle Marvin and a simulation to show cars crossing without stopping.

A short BicycleDutch episode showing how Dutch junctions with protected cycle paths are laid out. It argues these are proven, non-experimental designs that make intersections safer for cyclists.

A short clip of Meskel Square in Addis Ababa, a busy crossroads where vehicles and pedestrians mix with few apparent rules. Filmed in 2013.

Cities: Skylines experiment measuring traffic flow across 30 different four-way junction designs, comparing vanilla traffic AI with the TMPE mod.

A five-minute BicycleDutch episode showing how Dutch junctions are designed so cyclists and pedestrians can cross safely. It explains the layout choices that separate and protect them.

Chris Urmson, head of Google's self-driving car program, shows footage of how the car perceives the road and decides what to do. Examples include cyclist hand signals, school buses, police officers and complex intersections.
