PROPOSAL OUTLINE
• Proposed System
• Preliminary Design
• Applications
• Worker Safety
• Business model
• Conclusion
PROPOSED SYSTEM
For single lane streets, two flaggers are
required for any construction site to re-route
traffic.
Each worker gets paid between $15-25/hr.
PROPOSED SYSTEM
Two portable traffic lights will replace the
flaggers.
Each light will have two LEDs, a Battery,
wireless capable microcontroller, and a
pressure sensor. Time permitting, recharging
solar panels may be included.
A master control will be given to the
supervisor on site.
PRELIMINARY DESIGN
Each light uses:
- Arduino Microprocessor
- Zigbee wireless module
- 12volt rechargeable battery
- 12volt LEDs (Red and Yellow)
- Resistors, BJTs, diodes, and
voltage regulators
- Differential pressure sensor
APPLICATIONS
The system is not specific for construction site traffic
and maybe used for:
• Overnight Construction Sites
• To temporarily replace malfunctioning or under
maintenance traffic lights
• Temporary traffic control in congested areas
• Emergency response traffic reroute
• Remote area traffic control (mining sites)
WORKER SAFETY
More than 40 cases of flagger accidents have been claimed with Work Safe BC from
2008-2010. These claims on average cost Work Safe BC $14m.
By minimizing or eliminating the need of flaggers, we will be saving lives.
BUSINESS MODEL
Two flaggers at an average of $40/hr with an
approximate 70hour per week = ~$2,800 per site,
per week.
Current heavy duty portable traffic lights = ~$50,000.
If a system of two light weight lights were sold at
$50,000, the system will be paid for in approximately
14 weeks.
For an industrial release system materials would
usually cost ~$5,000, without labor.
CONCLUSION
The system replaces two workers with a traffic light
system.
The system has many applications for temporary
traffic reroute.
The system reduces accident risks and saves lives.
The system is profitable for industrial use.
The system is dynamic, smart, and easy to deploy.
The system is automated, but a master switch maybe
considered for the site supervisor.
