GB/T 42442.1-2023Smart city - Smart parking - Part 1: General requirements (English PDF)

Foreword

This document was issued on 17 March 2023 by the State Administration for Market Regulation; Standardization Administration of the PRC and takes effect on 1 October 2023.

It is a GB/T standard: recommended rather than compulsory, but it is the text a Chinese reviewer applies when assessing a submission.

1 Scope

GB/T 42442.1-2023 sets the overall architecture for smart parking in a city, as the first part of GB/T 42442. Clause 5 establishes that architecture and clauses 6 to 9 work up through its layers: Internet of Things perception, described in the text as unified sensing and intelligent edge processing that supplies data collection and control; network communications, treated as the networks connecting equipment to each other and to the platform; computing storage; and data support. Clause 10 covers application services and divides them by who is served — public services, operation services and regulatory services. That division is the one that matters, because the driver hunting a space, the operator billing for it and the authority policing kerbside rules all read the same occupancy data for different ends, and a platform built around only one of them cannot serve the other two. Clause 11 sets security requirements and refers to GB/T 22239-2019 and GB/T 40645-2021, while clause 4 lists the abbreviations used. Written for city transport authorities, parking operators, and vendors building parking platforms and roadside sensing equipment.

This document establishes the overall architecture of smart parking, and specifies the basic

requirements for Internet of Things perception, network communication, computing storage,

data support, application services and security, etc.

This document is applicable to the planning, design, construction, operation and maintenance

of smart parking.

3 Terms and Definitions

The following terms and definitions are applicable to this document.

3.1 smart parking

Smart parking is a smart application that utilizes information and communication technology

to realize the monitoring, management and service of urban parking resources, and improves

the utilization rate of urban parking resources, parking management efficiency and parking

service quality.

3.2 parking lot

Parking lot refers to the site, as well as aboveground and underground structures for motor

vehicle parking. Generally speaking, it is composed of entrances and exits, parking spaces,

passages and ancillary facilities.

NOTE: the parking lot referred to in this document includes on-street parking spaces and urban

public parking lots. Among them, urban public parking lot refers to the independently

occupied parking lot for public services located outside the red line of the rod and the not

independently occupied parking lot for public services built by constructions.
