Within the framework of RadOnTime the effects of the signal control measure on traffic safety and efficiency will be investigated in real traffic and using a bicycle simulator. Countdown times will be installed at selected research intersection in Munich. Safety and efficiency parameters will be derived from trajectory data from all types of road users, which will be extracted from video data using automated video analysis. The acceptance and evaluation of various design alternatives for the control measure by different bicyclists will be examined in a bicycle simulator study.
The number of red signal violations as well as the waiting time for bicyclists are both expected to decrease by 10% as a result of the prototypical implementation of the countdown timers. This will be accompanied by the significant reduction in safety critical situations.
