1. Presented By: Faisal Hamood Team Members: Faisal Hamood, Thomas Howell, Luis Herrera, Nick Allen, and Nicolai Bailly. Supervisor: Dr. Fayez Gebali. PORTABLE TRAFFIC LIGHT SYSTEM

2. PROPOSAL OUTLINE Proposed System Preliminary Design Applications Worker Safety Business model Conclusion

3. 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.

4. 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.

5. 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

6. 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)

7. 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.

8. 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.

9. 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.
