On October 10, the standard “Technical Requirements and Test Methods for Road Traffic Signal Information Services Based on Mobile Internet” led by Smart Vehicle Innovation and Development Platform (Shanghai) Co., Ltd.(hereinafter referred to as the “Platform Company”) was officially released.
Based on full investigation and reference to relevant domestic and foreign standards, this standard clarifies the technical requirements for mobile Internet-based road traffic signal data collection, processing and release, covering system architecture, interaction processes, service quality and indicator requirements, and data quality.
Testing methods and other aspects.
By organizing industry experts to discuss, design system architecture, define service quality indicators, design test methods, and carry out actual test and verification work, the standards were verified in the demonstration area, and the test results generally met expectations.
, In terms of architecture, this standard defines the reference architecture of the road traffic signal information service system, including traffic signal data sources, road traffic signal data source platforms, road traffic signal information service operation platforms and vehicle terminals, as shown in the following figure.
And define the basic information interaction process and information interaction content.
, Figure System reference architecture.
In terms of data quality, the standard is divided into two dimensions: L3 and above, and L2 and below.
It defines 10 indicators such as signal color accuracy, signal color jump ratio, signal countdown accuracy, and intersection continuity.
, and designs the corresponding test process and evaluation method.
, The formulation and implementation of standards will help promote the coordinated development of intelligent connected vehicles and road infrastructure, improve the accuracy and real-time nature of road traffic signal data, enhance the perception capabilities and driving safety of autonomous vehicles, and promote intelligent transportation systems.
Construction and application.
