Introduction
0.1  Background
With the integration of core technologies from the Fourth Industrial Revolution—such as Artificial
Intelligence (AI) and big data—along with advancements in streetlighting systems, the development and
deployment of smart streetlighting platforms that deliver comprehensive information related to traffic,
safety, and the environment are spreading rapidly.
The smart streetlighting management platform (SSMP) is a system in which detection devices—such as
closed-circuit television (CCTV) cameras and radar sensors—are installed on roadside streetlights to collect
and analyse real-time environmental data. Based on this analysis, the platform provides a range of services,
including accident risk alerts, pedestrian safety support, identification of illegally parked or stopped
vehicles, and relocation warnings.
For instance, when a pedestrian is crossing at a crosswalk under a flashing green signal and a speeding
vehicle is detected approaching the area, the SSMP activates a variable message sign (VMS) and gobo
lighting to issue a visual warning to the driver. Simultaneously, an audible alert is broadcast via speakers to
inform pedestrians of the approaching vehicle, thereby prompting a swift and safe retreat to the sidewalk.
This document introduces the concept of the SSMP. While the technical content reflects an initial Korean
implementation, the purpose of this document is to provide illustrative reference information that can be
adapted and applied by other countries and regions considering the adoption of similar platforms, thereby
ensuring global relevance.
0.2  Overview
This document introduces the SSMP, developed and implemented in Korea, presented here as a representative
case study. While the content reflects the Korean implementation, it is intended as an illustrative, not
prescriptive, reference to support international stakeholders planning to establish similar systems and to
ensure adaptability across diverse national contexts. It presents general information, system components,
and representative use cases of the platform.
The general information section outlines the SSMP’s purpose and provides an overview of key service
areas—such as crosswalks, crossroads, school zones, tunnels, and bridges—along with methods for
delivering safety information, including alerts, warnings, and guidance.
The system components section details the platform’s components and core functions, which are categorized
into the central platform, local platform, intelligent edge units, and smart streetlighting.
The use case section describes each service provided by the SSMP and explains interactions between its
various components. These use cases are based on the Korean implementation and are presented as
illustrative examples, not prescriptive requirements, intended to support international understanding and
potential adaptation in diverse regional contexts. Annex A provides data definitions established during the
development and operation of the SSMP in Korea. In addition, a comparative table is included to support
the adoption and operation of SSMP in different national contexts, aligning the data used in Korea with
international standards such as National Transportation Communications for Intelligent Transportation
Systems (NTCIP) standards and European Telecommunications Standards Institute (ETSI) standards. The
comparative information is provided for reference purposes only, without reproducing normative content
from those standards, thereby supporting interoperability and facilitating adaptation in global contexts.

5 General Information
5.1 Overview of the smart streetlighting management platform (SSMP)
The SSMP integrates data collected from CCTV, radar, and RWIS sensors in areas with high accident risk—
locations where traffic accidents frequently occur. By analysing this integrated data, the platform detects
potential incident scenarios that can lead to road traffic accidents and provides corresponding safety
information.
The types of event scenarios detected by SSMP include the following:
— Jaywalking pedestrians (e.g., signal violations or crossing outside designated crosswalks).
— Pedestrians with insufficient green signal time for crossing.
— Vehicles violating the stop line.
— Risk of rear-end collisions involving unprotected left-turn waiting vehicles.
— Risk of collisions between vehicles and pedestrians during right turns.
— Presence of illegally parked or stopped vehicles.
— Movement of pedestrian groups near roadways.
— Approach of vehicles exceeding speed limits.
— Presence of slow-moving vehicles ahead.
— Occurrence of unexpected hazards ahead.
The IEU is a key component of SSMP. It collects and analyses real-time environmental data through sensor
devices, including object classification (e.g., object types such as vehicles and pedestrians, along with their
location, direction, and speed). When an event scenario is detected, the system delivers safety information
(such as hazard alerts, warnings, guidance, and related information) via information provision devices, in
accordance with predefined response scenarios tailored to the specific type of event. At this stage, the IEU
exchanges and shares information with other IEUs through the local platform to enable coordinated traffic
safety management across sections where smart streetlights are installed.
The SSMP features the following three key characteristics:
— Through information linkage across the IEU, local platform, and centre platform, the SSMP can detect and
respond to hazardous situations not only at specific points but also across extended roadway sections.
— Each IEU is capable of independently analysing the surrounding environmental data it collects and
detecting event scenarios in real time, providing safety information to road users in a timely manner.
This reduces the time required for the traffic information centre to review and assess the data collected
by the IEUs, thereby alleviating the operational burden on system administrators.
— The SSMP offers the advantage of enabling the addition or expansion of service scenarios in the field
through software updates to the local platform—one of the core components of smart streetlighting—
without needing to replace existing hardware.
The benefits of the SSMP are as follows:
— While existing roadside streetlights have traditionally functioned as auxiliary facilities to enhance
night-time visibility, the application of sensors, AI, and ICT technologies transforms them into intelligent
traffic safety infrastructure capable of detecting accident-related events and delivering real-time safety
information.
— By leveraging infrastructure-to-vehicle ICT technologies, the SSMP can extend both its service coverage
and functional scope, making it applicable to broader domains such as C-ITS and smart city initiatives.
5.2 Priority service coverage areas
The service coverage areas designated in Korea’s SSMP implementation and pilot project are as follows (see
Figure 1).
— Crossroad.
— Crosswalk.
— School zone.

5.3 Warning information provision method
When an event with the potential to cause a road traffic accident is detected, the SSMP provides safety
information to road users through visual and auditory signals. The types and methods of information
provision devices are summarized in the "information display" row of Table 2.
Examples of how information provision devices are applied across the different SSMP service coverage areas
are illustrated in Figure 2.
