Optimization of traffic flows to increase the capacity of urban unsignalized junctions

Abstract

Regular studies of traffic flows allow obtaining the actual parameters of the vehicle movement. Field observations using unmanned aerial vehicles help to optimize the research due to the wide capture field of the video camera, which allows comprehensively assessing traffic flows simultaneously utilizing all approaches to the intersection. When designing a road network, it is necessary to determine the capacity of all its elements. The characteristic elements are unsignalized intersections and junctions, the capacity of which largely depends on the intensity of the main and secondary directions, the behavior of drivers and the adoption by drivers of intervals between cars of the main traffic flow when entering the intersection.

The Unsignaled Intersection Performance Analysis of Arterial Access Road at Karawang Barat 1Toll Gate, West Java

“…The capacity of the unsignaled interchange depends on the composition of the flow, the intensity of the mixed flow of traffic flows, and the probability of the driver receiving a secondary boundary interval of the direction of movement (Pospelov, Kostin, Martyakhin, & Komarova, 2021). Traffic volume Congestion is the number of vehicles passing through a point on a section of road in a specific time interval expressed in units of vehicles at a particular time (Desmi & Yanti, 2019).…”
