Management Systems

Dynamic Junction Control System

Dynamic Junction Control System, CHAOS®- optimizes signalization durations at junctions based on vehicle densities. CHAOS consists of two sub modules.

Vehicle Counting System

VIERO® Vehicle Counting System, VIERO®, is able to count vehicles with its image based analysis capability 24/7, under any weather condition. The system can send the analyses to a remote center via network connection.

Dynamic Junction Control Unit

CENTRIS is a unit that provides remote management and control of signalized junctions. The unit is integrated with the Junction Controllers and provides remote management of phase durations and operation mode of Junction Controller, notifies the operators about malfunctions at the junctions and enables remote monitoring of the junctions in real time.

Traffic Analysis System

Bluetooth Based Traffic Analysis System, BLUESIS, can calculate average travel time between two or more installation points in real-time and shares the information with drivers on mobile platforms and/or Variable Message Signs (VMS).

Enforcement Systems

POINTR 3000 and POINTR Moonlight are an integrated ANPR system which recognizes number plates, brands and colors of the vehicles within the range.It can keep the collected data in the internal memory or transmit to a remote server via internet.

POINTR K3000, POINTR® K3000 detects the vehicles that violates red lights. The system helps improving traffic safety by minimizing the traffic accidents due to red light violation.
POINTR P2000 has the ability of automatically detecting number plates of the vehicles which violate parking rules.

Traffic Management Center Software

Traffic Control Center Software, METIS, as a part of CHAOS® System is a completely web based control center software which is based on digital maps. METIS can control and communicate with the junctions in real time according to the international communication standards and keep on the communication for 24/7. METIS has the capability of statistical analyses according to live and historical traffic data.

Tunnel Incident Detection System, SPECTO

SPECTO® is a vision based automatic incident detection system that reduces the operator reaction time by informing the operator against abnormal cases likely to occur in the tunnels. SPECTO® can be integrated into any analog/digital camera systems available in the tunnels.

Simulation Software

Traffic Simulation

PTV Vissim is the ideal tool for state-of-the-art transportation planning and operations analysis. The software is designed to assist you in realistically simulating and balancing roadway capacity as well as traffic and transport demand.

Transport Strategy

PTV Visum is a comprehensive, flexible software system for strategic traffic and transport planning. Around the globe, the system is used for metropolitan, regional and state-wide infrastructure planning.

Traffic Impact

PTV Vistro is the ideal tool for all your traffic analysis needs. Its intuitive user interface places all functions at your fingertips so that you can keep traffic flowing at the touch of a button.

Pedestrain Traffic Simulation

Walking always was and remains the most prevalent mode of transport. But unlike vehicles, pedestrians do not follow strict rules. They spontaneously stop, change directions or make sudden turns. We have accepted the challenge and have developed a solution that takes into account the psychology of human walking behaviour.
