Foreword

This document is in accordance with the provisions of GB/T 1.1-2020 "Guidelines for standardization work Part 1: Structure and drafting rules for standardization documents" Drafting.

This document is Part 1 of GA/T 2176 "Guidelines for the Installation of Risk Prevention and Control Equipment on Accident-Prone Road Sections". GA/T 2176 has been published.

The following sections.

--- Part 1: Basic principles.

Introduction

In order to solve the problem of prominent traffic operation risks in accident-prone sections and multiple but unsystematic monitoring methods, it is necessary to guide the establishment of risk management system for accident-prone sections.

This document is prepared to establish an integrated risk prevention and control equipment system for risk monitoring, identification, assessment, early warning and response.

Recommendations on the installation of risk control equipment for accident-prone sections such as bridges, long downhill slopes, long tunnels, and sharp bends.

Partial composition.

--- Part 1: Basic Principles. The purpose is to establish the basic principles for the installation of risk prevention and control equipment on accident-prone sections of road.

--- Part 2: Extra-Large Bridge Sections. The purpose is to establish recommendations and methods for the installation of risk prevention and control equipment in extra-large bridge sections.

--- Part 3: Long downhill sections. The purpose is to establish recommendations and methods for the installation of risk prevention and control equipment on long downhill sections.

--- Part 4: Long tunnel sections. The purpose is to establish recommendations and methods for the installation of risk prevention and control equipment in long tunnel sections.

--- Part 5: Sharp bends. The purpose is to establish recommendations and methods for the installation of risk prevention and control equipment on sharp bends.
