New study on expectations and reality of safe overtaking maneuvers in bicycle traffic
Subjective impressions of safety differs according to the type of road and speed limit Dangerous situations can develop when cyclists are overtaken by cars. How threatened or safe cyclists feel during an overtaking maneuver depends on the type of road. They expect to be safer on roads with a speed limit of 30 kilometers per hour (kph), as well as on living streets, bike streets, and roads with cycle lanes.

New AI method analyzes Swiss fleet consumption
New AI method analyzes Swiss fleet consumption
How much does a country's vehicle fleet consume on average? How does it change from year to year? With the increasing number of electric vehicles and more and more "crossover" models that can hardly be assigned to one vehicle segment, analysis is becoming increasingly difficult. researchers analyze databases using deep learning methods - and can make precise statements: In which region of the country do the fattest cars drive? What can car buyers do to reduce CO2 consumption? In recent decades, there have been major technical changes in new cars.
