ATCS

Each year sees greatly increasing urban traffic volumes, densities and intensities resulting into growing number of traffic jams.

The ATCS is designed primarily for improving traffic control efficiency at traffic lights, reducing the total number of vehicle delay at intersections, and ensuring greater comfort and safety for travelers while reducing harmful emission.

The ATCS relies on proper traffic control at various with adaptive traffic light control being the most efficient and advance method.

The system is adapting to traffic conditions continuously, responding to traffic intensity changes, contingencies, traffic accidents, etc.

The core components of the automated traffic control system include:

Vehicle detectors

Smart road controllers

Top level software

Network interfaces between field hardware at intersections and ATCS central software via encrypted wired and wireless communication channels.

Control center hardware:

Switching hardware

Central server

Automated operator workplace

Videowall

Intersection hardware:

Pedestrian traffic lighths

Road traffic lights

Road controlls

Pivot cameras

Vehicle detectors

Switching hardware

Traffic control level

Improving controls increase road network throughput overall.

Currently, nearly all controllers in the Russian Federation rely on fixed plans. This a legacy approach preventing adaptation to continuously changing traffic conditions.

Control Algorithms

Various traffic control patterns and algorithms are used throughout cities The most efficient solutions for improving of traffic conditions may be found on a case by case basis.

Fixed Plans:

Controllers rely on fixed daily programs.

Traffic lights respond in no ways to changing traffic conditions and operate independently of adjacent intersection

Local Adaptive Mode:

Phase and cycle durations are calculated relying on detector readings.

Traffic lights adapt to traffic conditions on a real time basis but operate independently of adjacent intersections.

Network Adaptation:

ATCS synchronises all traffic lights to ensure that traffic flows pass all subsequent intersections without stopping.

Traffic lights adapt to traffic conditions on a real time basis and operate depending on adjacent intersections.

Local Adaptation

Adaptive control system performance is visible even at individual intersections. It requires no traffic control centers as all the hardware is within the traffic light.

Video detectors provide continuous traffic flow parameter information for all directions and lanes. The road controller receives the information and processes it depending on the selected algorithm to streamline phase durations for specific traffic directions.

Network Adaptation

Usage of control centers enhances traffic control capabilities. All controllers and peripherals form a common network using wired and wireless communications. It allows reaching a new level, that of network adaptation.

Control Centers allow:

Centralized control of entire cities from a common point;
Prompt response to contingencies (traffic accidents, traffic jams, vehicle failures);
Video monitoring of traffic conditions at all intersections;
Getting information on current statuses of all field equipment pieces.

Networking benefits include:

Remote setup of controller and hardware operating modes;
Graphical display of traffic processes at intersections;
Display of system messages and automatic SMS and email forwarding thereof;
Centralized database maintenance with all parameters, and graphical display thereof;
Multiple system access levels with various powers (5 access levels);
Traffic incident and jam identification system;
Public transit prioritization;
Mobile device management (Android and iOS support);
Light Web interface versions;

РVarious control algorithms:

adaptive control of traffic light groups relying on vehicle detectors;
flexible daily coordination plans;
green times and green streets;
adaptive green times.

The software is supplied in two versions being the server solution, and the intuitive Web client.

Vehicle detectors are versatile products installed at thoroughfares to collect traffic data or installed within hardware suites ensuring automatic traffic control at traffic light locations.

The primary task of vehicle detectors is transmitting dynamic traffic information for each lane of the intersection such as:

All instruments have network interface for connecting to road controllers and control centers, allow connecting multiple information recipients simultaneously, and also allow direct interfacing with road controllers (bypassing control centers) in the local adaptive control mode.

Surveillance Cameras

Surveillance cameras installed at traffic lights ensure round the clock monitoring of traffic conditions and rapid responses to contingencies as well as video streaming to customer servers.

Intersection video surveillance suites include fixed cameras for each of the traffic directions as well as circular scanning dome cameras controllable remotely from traffic control centers to allow prompt assessments of traffic conditions at any intersection areas.

Video surveillance covers all traffic directions at intersectionsе

Recognition

Video streaming from all sides of intersections is continuous. Servers retain videos for 30 days minimum. Operators may use motorcar license plates at any time to request motorcar routes and intersection passing times.

Video surveillance covers all traffic directions at intersections

It records and retains data including:

Motorcar license plates;
Vehicle types;
Vehicle makes and models;
Photos of vehicles passing intersections;
Videos of vehicles passing intersections.

Neural Networks

Awareness of individual routes of all individual motorcars allows us to forecast the urban traffic conditions overall. It improves quality of traffic control solutions. The system reviews routes of various vehicle types and models.

Special neural network algorithms are in use to create vehicle route chains.
