Measurement and analysis of traffic delays in front of controlled intersections based on quadcopter images

Abstract

The paper presents the results of studies of the congestion of a regulated intersection of the city based on the use of quadcopter technologies for recording the dynamics of vehicle flows during times of peak traffic, when it can be problematic to determine the parameters of traffic delays due to the limited visibility of stationary means of video observation. The selected calculation method for the adequacy of transport delay calculations requires precise geo-positioning data of a number of cars at the intersection, which is fully provided by quadcopter surveying. The results of the calculations can be used to adjust the parameters of the intersection regulation, or to assess its environmental friendliness and economic losses at times of the highest traffic loads. Transport delays at regulated intersections of large and even medium-sized cities lead to the accumulation of significant concentrations of harmful emissions, which can many times exceed the maximum permissible concentrations, and this exacerbates already existing environmental problems. It should be noted that the use of quadcopter surveying technologies is a method of the transition period to the introduction of modern geo-information technologies and intelligent electronic systems based on satellite navigation data, which can be adaptive traffic control systems. The transition to adaptive traffic control systems is a promising direction of optimal traffic management, which provides local adaptive control of the most complex and important intersections of the transport network.
