SMART CROSSROADS
Smart Intersection is the foundation for building a scalable intelligent transport system.
It provides monitoring
and analytics of traffic traffic at intersections of city streets,
redistribution of traffic flows to increase the capacity of intersections
using dynamic traffic signal management.
The introduction of ITS must begin with the creation of "Smart Intersections"

— Subsystem for informing road users
— Subsystem for notification of emerging events
Modules of the following ITS subsystems are already integrated into the system:
— Video surveillance subsystem
— Environmental parameters monitoring subsystem
— Traffic light control subsystem
— Subsystem for detecting traffic and pedestrian flows
— Subsystem for monitoring compliance with traffic rules and transport control
The integration module provides
information exchange (open API)
and interaction

forecast of arrival at the stopping point)
— Information systems for operational services and maintenance services
— Vehicle detectors
— Traffic light controllers
In addition, it is possible to integrate
with any other ITS subsystems, as well
as organize information exchange
with similar EPUTS systems

ITS INTEGRATION POSSIBILITIES
VIDEO SURVEILLANCE SUBSYSTEM
Traffic surveillance
Video surveillance of the condition of the road surface
The main tasks of the subsystem:
Video surveillance of the road infrastructure
Traffic accidents and emergencies detection
Transfer of photo and video data to other ITS subsystems
Storage of photo and video data
Thus, the implementation of the video surveillance subsystem provides
in real time:
As part of the ITS, the video surveillance subsystem is designed for visual observation of a section of the road network in order to assess the state of transport and pedestrian flows, road surface and road infrastructure elements, identify road traffic accidents, facts of traffic violations
— Obtaining data on traffic and pedestrian flows
— Identification of emergencies and emergency situations on the road network
— Control of the movement of vehicles
— Identification of violations of traffic rules

LIGHT CONTROL SUBSYSTEM
Implementation of traffic light control of traffic flows
Collecting data on traffic flows at the approaches to the intersection for the purpose of adaptive control of the traffic light object
The main tasks of the ITS subsystem:
The purpose of the ITS subsystem: ensuring optimal traffic light regulation
at the intersection of traffic flows in order to reduce the likelihood of an accident and taking into account the current traffic situation
— Centralized coordinated management
of technical means of regulation and organization of
traffic according to prepared scenarios
(Library of coordinated management plans)
Main functional characteristics:
— Automatic selection of traffic control scenarios, depending on the current traffic situation, based on data coming from adjacent and external systems
— Adaptive coordinated management of technical means of regulation and organization of traffic on certain sections of the road
— Dispatch control

SUBSYSTEM FOR MONITORING ENVIRONMENTAL PARAMETERS
Collection of data characterizing environmental parameters in the ITS area
Processing of the received data
The main tasks of the subsystem:
Data storage
Data transfer to other ITS subsystems
Transfer of photo and video data to other ITS subsystems
Storage of photo and video data
Within the ITS, the subsystem for monitoring environmental
parameters is designed to monitor data
characterizing environmental conditions
in the ITS area for transferring them to other subsystems
— The implementation of a subsystem for monitoring environmental parameters requires the installation of a smart traffic light SmartLight at intersections, in which environmental sensors will be mounted.
— The set of monitored environmental parameters is determined by the type and number of sensors used.
— The concentration of the following pollutants in the ambient air can be continuously monitored: carbon and nitrogen oxides, nitrogen dioxide, sulfur dioxide
— Monitoring results are saved in the
database and can be used for further analysis.
— Depending on the set of installed sensors, it is possible both to monitor environmental parameters in the area of the road network, and to detect emissions of harmful substances not associated with the movement of
vehicles (for example, emissions from industrial enterprises).
In this regard, as part of the first stage of implementation, it is also proposed to install SmartLight traffic lights near large industrial facilities.

SUBSYSTEM FOR DETECTING
TRANSPORT AND PEDESTRIAN FLOWS
For this purpose, analyzers of WI-FI connections are also built into SmartLight traffic lights installed at intersections.
Implementation of a subsystem for tracking traffic
and pedestrian flows (in addition to the functionality
inherent in the video surveillance subsystem)
is proposed on the basis of a Wi-Fi network
The implementation of this functionality provides the calculation of the matrix of correspondence between pedestrians and vehicles.

Based on this matrix, it is possible to evaluate the characteristics of traffic and pedestrian flows, track crowded places

"DIGITAL TWIN" ROAD
A digital model ("digital twin") of a road is a database of spatial data of road infrastructure objects, road markings, road signs, traffic management schemes, objects of an intelligent transport
system and a high-precision graph of the road network.
— Navigation solutions
The digital model of the road is intended
to be used as part of a single
ITS information space for:
— creation of a platform for automatic traffic control of vehicles
— the content of complete and up-to-date information about the transport infrastructure of the city
— Creating the basis of transport infrastructure for use by unmanned vehicles
At the same time, the digital model of the city can serve as a "foundation" for building a digital twin of the city.
The digital twin of a city is a smart 3D city model
that accurately represents the streets, buildings, and other infrastructure of a physical city in a virtual model. Many digital elements are updated in real time, which allows you to track the movement of people, vehicles, track the location of emergency services for a faster response to emergencies.
In addition to the city's transport infrastructure, the digital twin is able to track electricity and water consumption.

SUBSYSTEM OF NOTIFICATION
ABOUT EMERGING EVENTS
Taking into account the priority of the goal of ensuring
road safety within the framework of the ITS implementation, the proposed installation of SmartLight smart traffic lights at city intersections will provide a smart lighting function. When a prohibitory signal of a pedestrian traffic light is used, the sidewalk is illuminated,
when the enabling signal is turned on for pedestrians, an additional illumination of the pedestrian crossing zone is turned on.
— Subsystem for notification of emerging events
The following ITS subsystems
are already integrated into the system:
— Video surveillance subsystem
— Environmental parameters monitoring subsystem
— Traffic light control subsystem
— Subsystem for detecting traffic and pedestrian flows
— Subsystem for monitoring compliance with traffic rules and transport control
This significantly increases the visibility and safety of pedestrians, especially at night, and reduces the risk of accidents
at pedestrian crossings.
