Safe School Zone (Busan)

Safe School Zone (Busan)

To scan vehicles and pedestrians using video cameras which are embedded in street lights and vehicle detecting sensors to prevent car accident in school zone by giving alarm sign to cars and pedestrians using digital signage and ground LED light devices. In case of violating stop line, reporting services to a related government agencies
to transform street lights into service node by replacing them with LEDs that have control node with various sensors, CCTV and communication modules

Impact statement

- To scan vehicles and pedestrians using video cameras which are embedded in street lights and vehicle detecting sensors
- To prevent car accident in school zone by giving alarm sign to cars and pedestrians using digital signage and ground LED light devices
- In case of violating stop line, Reporting services to a related government agencies
- To transform street lights into service node by replacing them with LEDs that have control node with various sensors, CCTV and communication modules

Challenges:

-Data access into or integration with existing public service / first response systems (Integrated city op. center)
-Legal/regulation-related issues i.e. no regulations for blinking street lights, adding color-tunable signage, etc.
-Lack of Standardization for LED Fixtures and Controls

Major Requirements:

- Clear understanding patterns of accidents in school zones and road types
- Securing optimal solution for safety services in school zones
- experiences in similar cases
- City platform compatibility
- Engineering design capability for scalability and upgrades
-IoT Node integration into LED Cobra head
-New type of Cobra head type development : CCTV, Sensor integrated …
-City wide wireless network (LoRa) deployment
-Data integration into Integrated City Op. Center

Key Performance Indicators:

- Decrease Pedestrian accidents rate by 20%
- Decrease Violating stop line rates by 30%
- Energy reduction by more than 50% (as compared to conventional lighting luminaires)
-Improve accuracy of incident/accident reporting by more than 50%

Measurement Methods:

- By comparing energy bills for energy savings,
- By comparing statistical data

Standards/Interoperability:

- Global Standards compliant smart city platform (oneM2M)
- HW interface : NEMA 5/7 pin receptacle
- Wireless Communications : Wi-Fi and LoRa support
- Lighting Control : TALQ-compliant management system

Replicability, Scalability, and Sustainability:

- Enabling Scalability and Replicability by adapting oneM2M standard
- Evolving but consistent API : Communication API of the control Node and related gateways
- Node: Industry standard-based simple push-and-turn installation and management

Project Impacts:

- Improved public safety/security in school zone to deter crimes and improve sense of security
- Reduction in pedestrian and vehicle accidents in school zones
- Economic wireless LED street light controller that would build an economic smart city infrastructure on which to build additional citizen services (no need to dig up streets to lay out wires…)
- Immediate saving on energy bills and City O&M cost

Demonstration:

Phase I Pilot/Demonstration June 2016:

A 250 meter long busy street (including 3 crosswalk) with LED light(with CCTV and sensors) and digital signage would
- have brighter, more crisp lightings
- have sensor-driven adaptive light on/off and dimming providing enough lights on foggy days,
- have audio- and vibration-based panic button service
- have safer environment for pedestrians

Phase II Deployment June 2017:
Above mentioned street with environmental sensors and pedestrian crossing integrated providing people and automobile counting as well as traffic monitoring to minimize time spent on the road waiting
