The introduction of countdown timers at signalized intersections changes the perception of traffic control signals by drivers. Devices can have negative impact on safety, manifested by an increased number of dangerous behaviour events such as early starts during red signals and rear end collisions. On the other hand countdown timers can affect the traffic conditions at intersections, as drivers receive advance information on the changes of traffic lights. This information favours drivers earlier starts and lower time losses for intersection entries. The problem is analysed using video data collected at intersections using UAVs. Intersections with varying traffic conditions are chosen as test sites. Traffic is observed at whole intersections including approaches with queues of up to several vehicles. Measures of drivers behaviour changes such as: start time and intersection travel through speed related to the intersection traffic conditions are discussed.
