INTRODUCTION TO SMART CITY
Definition
• Smart City - incorporates information and communication
technologies.
• To enhance the quality and performance of urban services.
• Such as energy, transportation and utilities - to reduce resource
consumption, wastage and overall costs.
• Smart city – are hyper-connected cities - Internet of things (IoT)-
using sensors - to collect homogeneous data.
• Coordinating data collection and analysis across systems and sectors.
• Technologically equipped to improve the lives of their residents.

IOT IN SMART CITY
• What is IoT?
• A system of computing devices, mechanical and digital machines, objects,
animals or people that:
• Has an unique identifier (UID)
• Has the ability to transfer data over a network without requiring human help.
• Fundamental characteristic of smart cities:
Collect and analyze data to efficiently manage resources
→ IoT is the solution

Data is taken
using sensors:
Surveillance
camera, thermal
sensor, etc.
→ Assesses performance
of equipment
→ Proactive maintenance
→ Uncovers new patterns
and tendencies
→ identifies the problems
before the damage is
done

Reduce minor conflicts
Significant fall in serious accidents
Don’t wait for crashes to happen!
TECHNOLOGY: VIDEO ANALYTICS TOWARD VISION ZERO (cont)

Leverage city’s traffic camera system to:
➢ monitor counts and travel speed of all road user
groups (vehicle, pedestrian, and bicycle)
➢ Document the directional volume of all road user
groups in an intersection
➢ Assess unsafe “near miss” trajectories and
interactions between all road user groups.
