Abstract. Urban environments are more or less characterized by active travel modes, including the bicycle usage. Present transport infrastructure for bicyclists can often not serve the high traffic volumes, especially in rush hours. Therefore, introducing novel and specific traffic control strategies for bicyclists might serve as supportive element for improving bicycle traffic efficiency and safety. We evaluate a traffic control strategy implying countdown timer displays for bicyclists with one device being permanently installed in Munich (Germany) by (1) extracting cyclist trajectories from video observations before and after the installations, and, (2) introducing a bicycle simulator scenario via a map design approach. The latter includes a sequence of fictional and real road intersections and goes beyond evaluating the present countdown timers in VR, since different other countdown timer display designs are being tested. The whole bicycle simulator study consists of test rides and subsequent questionnaires with test subjects. We explain the design of the first simulator study and show selected results, which imply significant new insights resulting from the first 30 test rides and questionnaires.
