Opportunities to improve road traffic on short-length road connections by correlating intersection traffic lights

Abstract

The paper aims to explore the possibilities of improving road traffic in the central area of cities characterized by a longitudinal arrangement of the street network, with application for the case of Pitesti, where the road network in the central area consists of two main roads arranged longitudinally, having one-way regulated traffic, interconnected by several streets. A special traffic problem is reported in the city center: on the main road connecting the two boulevards, the vehicle storage space is insufficient - because the distance between the two road intersections is too small and there is no correlation between the Green phases of traffic lights in the two intersections. The research, based on traffic measurements performed with DataFromSky software and micro-simulation traffic analyses performed with Vissim PTV software, indicated that the best solution is the partial or total correlation of the green time from the traffic light intersections that delimit the connecting road artery. As, almost exclusively, the works dedicated to the correlation of green light of traffic lights treat the problem only along the road arteries, this paper raises a special issue and reveals the possibility of simple solutions, by correlating the traffic lights at the intersections connecting the main arteries.

Analyzing Escalator Infrastructures: A Pilot Study in Santiago Metro

“…This study included the opensource software Datafromsky (https://datafromsky.com/, access date: 2 August 2023) which may be an alternative to Guo and Zhang [29], who analyzed a subway station using the Yolo artificial vision library. These researchers expanded the use of Datafromsky which has been widely used in traffic analysis [35].…”
