|Bike track in Aarhus, DK. It is smooth, and it goes straight across the junction. The same priority rules apply both for cars and cyclists.|
Second, road users are always interacting and have to adjust to other road users. This is partly achieved through planning of roads and junctions. It is important to realize that adjustment is costly, usually involving breaking and speeding up again, and often maneuvering. Current cycle tracks put too much of these adjustment costs on cyclists. The tracks almost never go straight across intersections, even at the main thoroughfares, often forcing bikes to slow down to walking speed in order to cross curbstones and take sharp turns. Second, instead of dedicated bike lanes, cyclists are often expected to ride on pedestrian walkways. This is an acceptable solution only if these are wide and not crowded. The most critical points are typically bus stops, turns around street corners, and areas near pedestrian crossings. Sidewalks in these places are often narrow, visibility low, and many people standing and waiting. Now compare this with the car lanes at the same stretches. Those almost always retain their width, there are hardly ever obstacles like curbstones, and they go straight across the junctions. Most of the the adjustment costs are shifted to cyclists and pedestrians.
