First Free Flow frames have been installed on CRR

Workers have finished the installation of frames of Free Flow system on the third launch complex of the Central Ring Road (CRR). 

The system will become a component of a single Intellectual Transport System (ITS) for the entire ring road. The ITS of the CRR-3 will include three Free Flow frames, 75 transport flow detectors, 71 video surveillance cameras for automatic traffic control system (ATCS), and 7 weather stations. 

The necessary communication lines have been laid on the CRR-3 for the interaction of smart sensors of this launch complex and further transfer the obtained data to the Central Control Room (CCR). 
The CCR will serve as a basis for ATCS and Free Flow system equipment of the entire CRR, and new workplaces for personnel will be created. When the traffic on the ring road is opened, data from all sensors along the highway will be transferred to the Central Control Room. 

The obtained data, information on precipitation, mist, wind gusts and road accidents will be shown on seven dynamic panels to give notices to the drovers about bad weather, discomfort traffic, and changes in the speed limit. The data on weather will be used by the services in charge of CRR maintenance.
In addition, 40 variable message signs will be installed along the highway. They will allow to regulate speed limits and to optimize traffic flows.

With Free Flow system introduced in Russia for the first time ever, car drivers will pass along the CRR without stops, at that, toll collection points and barriers will be eliminated. 12frames for contactless toll payments will be installed on the Central Ring Road.

All of them will be equipped with video surveillance cameras, antennas and laser scanners. 
Antennas will read data from transponders, cameras will record car passages, identify state license plates of the cars, and “count” the number of axles. Laser scanners will be used to define overall dimensions of vehicles for classification purposes (passenger cars and cargo vehicles). Data from these devices will be transferred to an industrial PC also mounted here, on a support. The PC will consolidate the data obtained, create a transaction, record the fact of car passage and transfer the data to the CCR. 

CCR will be put into operation in the third quarter of 2020 before the opening of traffic on the CRR-3. 

The length of the third launch complex of the CRR amounts to 105.87 km. It is a four-lane highway with two lanes in both directions. The complex will connect M-11 and M-7 Kholmogory highways. Speed limit for passenger cars may be 130 km/h on this section.
