TL;DR
The results show that when the typical circular intersection of Fuye Square in Changchun City is changed to a planar cross intersection, the traffic capacity increases from 5326pcu/h to 9,906 pcu/h, and indicators such as queue length, service level, and average vehicle delay are all improved.
Abstract
This study addresses the challenges of insufficient traffic capacity and disorganized traffic flow at roundabouts, particularly under heavy traffic volumes. It investigates signal control optimization strategies for roundabouts and intelligent optimization methods for conventional signalized intersections. A traffic capacity optimization model is constructed, and a multi-index comprehensive evaluation model is based on the VISSIM simulation software. Taking the typical circular intersection of Fuye Square in Changchun City as the research object, the results show that when the circular intersection is changed to a planar cross intersection, the traffic capacity increases from 5326pcu/h to 9,906 pcu/h, and indicators such as queue length, service level, and average vehicle delay are all improved.
The operational status of intersections serves as a critical evaluation metric for urban road networks. For intersections featuring lane widening sections, once traffic volume reaches a certain threshold, queue spillover frequently occurs within these widened segments; this leads to a waste of effective green light tim...

Urban traffic congestion has become increasingly severe due to the rapid growth of vehicle demand, making efficient signal control a critical challenge. Existing traffic signal optimization methods typically focus on either isolated intersections or arterial coordination, lacking a unified framework that balances netwo...

Traffic congestion at many intersections in the Kathmandu Valley remains severe despite various traffic control and management measures, and the Lainchaur Intersection, a three-legged junction, is one of the most affected. The congestion is mainly due to uneven traffic distribution, vehicle composition, and the absence...

Urban traffic signal systems based on fixed-time plans may not adequately respond to variations in traffic demand among signalized intersections, limiting their operational efficiency. This study proposes a data-driven framework based on a Multilayer Perceptron (MLP) to support traffic signal timing optimization in an...

Vehicle-infrastructure cooperation (VIC), enabled by vehicle–road–cloud integration, enhances road capacity and network efficiency. For large-scale urban networks, optimal deployment of smart roadside facilities at various stages is crucial for effective traffic management and control. This paper proposes a method fo...

Traffic congestion remains a critical challenge in large cities. This paper presents a microscopic traffic simulation using a multi-agent approach that integrates an OpenStreetMap-derived road network, Intelligent Driver Model (IDM) for car-following, and MOBIL for lane-changing. The simulator targets a Bandung-scale R...
