Area traffic control – examples of solutions in the context of traffic modeling in cities

Abstract: The article lists practical solutions for area traffic control in cities. The advantages and disadvantages of existing solutions in this area are presented. The optimization methods implemented in practice are discussed in the context of shaping traffic flow in dense transport networks.A concept for introducing modifications to existing area traffic control systems is presented, which involves incorporating traffic measurements at intersections without traffic lights located outside the direct influence area of such traffic organization forms.
1. INTRODUCTION TO AREA CONTROL
Intelligent Transport Systems (ITS) constitute a collection of information technologies used in transport infrastructure and vehicles
[1,3,4,5]. One of the most popular applications of ITS is the construction of Advanced Traffic Management Systems (ATMS). ATMS is a set of ITS technologies implemented in a single system that enable the monitoring and management of road traffic. The goal of building such a system is to increase the efficiency of the road network, mainly the capacity at selected road cross-sections. The use of ITS in road traffic leads to measurable benefits:
• 5%-15% reduction in traffic congestion, • 5%-15% reduction in traffic incidents, • 10%-20% reduction in CO emissions and other environmental pollutants [2][6][8].
Area traffic control systems are often used in road layouts characterized by high time losses and queues. Area traffic control systems most often include the following subsystems: traffic signal control, intermodal communication integration, traffic safety, information, toll collection, trip planning, public transport management, navigation, traction control, vehicle-to-vehicle interaction control, and many others.
In relation to urban areas, the concept of Urban Traffic Management and Control (UTMC) is used. These are systems that monitor, control, and manage road traffic in urban areas, usually centrally controlled in a TCC (Traffic Control Center) (…)
