The paper presents conclusions drawn from an analysis of available methods of evaluation of road traffic conditions at approaches of signalized intersections and at interchanges. The analysis was performed due to the need to evaluate changes in the length and reach of vehicle queues, in order to gain insight into the process of development (accumulation, dispersion, concentration and relief) of the queues. The analysed methods included: conventional recording of the number of vehicles in a queue using a form, methods that involve the use of a voice recorder, photo camera, UAV (drone) and individual miniature video cameras (with built-in power supply) installed on streetlight poles along the relevant road section. Ultimately, the latter was chosen to evaluate the process of queue formation, having confronted the advantages and disadvantages of all the methods considered. The paper also describes the course of analysis and processing of measurement data using specially-developed computer software for the selected method. |
