Holographic intersections use two sensing methods: intersection radar + electric police/checkpoint cameras, integrating the industry's latest sensor technology, high-precision map technology, AI algorithms, etc. to build "smart + perception" capabilities.
The traffic organization of the intersection is related to the traffic situation of the section and the region. NRT is aimed at the pain points of the low degree of fine management of the intersection traffic and the difficulty of information integration , and has launched the traffic holographic intersection solution .
Holographic intersection is to use the intersection radar + electric police / card camera two means of perception, the integration of the latest industry sensor technology, high-precision map technology, AI algorithms to build "smart + perception" capabilities。By presenting all kinds of traffic operation indicators through the panoramic three-dimensional visualization platform of the digital twin of the city, the real-time traffic operation state can be quickly formed, which provides a favorable foundation for urban traffic management and governance.
System Architecture
NRT Holographic Intersection System is divided into : Inner Field System , Data Center , Outer Field System three modules .
The main function of outfield system is data acquisition; The core function of a data center is to carry out trajectory matching; The infield system is based on the company's self-developed NRT Digital Twin platform, which can realize the city digital base construction, signal control settings, traffic flow settings, traffic simulation evaluation and other functions.
System Highlights
Intersection simulation deduction as the highlight of the holographic intersection system , provides a basic digital base for the fine governance of urban traffic , through diagnosis → optimization → evaluation → control , to achieve closed-loop simulation evaluation of intersections .
01. Road Scene Visualization
Users can visually manage urban road topology, road facilities and equipment, road environment and other transportation infrastructure elements. At the same time, the platform provides scene editing tools, which can enable various elements in twin scenes to be modified, set up, etc.
02. Urban environmental visualization
The platform has built-in comprehensive urban building models and road facilities equipment models, which can be built and set up through simple drag / edit operations. At the same time, the weather renderer inside the platform can enable real-time visual rendering of urban weather.
03. Intersection signal control diagnostics and optimization
Based on the platform's internal control adaptive algorithm, based on the current intersection traffic, the intersection control adaptation can be optimized to achieve automatic optimization of single point control, automatic override of green wave control, and automatic omission of regional coordination control.
04. Intersections Evaluation
Through the internal detector of the platform, it is possible to detect the current vehicle operation indicators at the intersection in real time. Specifically, the overall intersection indicator IS, the visual display of lane indicators, flow analysis, the clearance of the import lane, the number of stops, the average delay analysis, the direction evaluation analysis, the signal evaluation analysis and so on. (The indicators are based on the National Standard GB / T33171-2016 of the People's Republic of China)
