5. Problem And Solution

6. Problem Dangerous intersections usually have visual restrictions that requires a driver to take a chance at pulling out in front of a vehicle.

7. Solution The solution is RADAR. A Radar Traffic Sensing device that could detect an on coming vehicle in a visual restricted area and warn the driver

8. Coffee Can Radar [4] [5] [10]

9. Constraints

10. Technical Constraints Flashing lightThe Flashing light must be visible in all weather conditions, during the day, and seen from a half of mile away. Detection RangeThe Radar must detect oncoming vehicles at least one fourth of a mile away. MicrocontrollerThe microcontroller must be able to take data from the radar and perform calculations in order to determine if a vehicle is approaching. AntennaThe antenna must be used to send out an appropriate signal to detect vehicles. Power RequirementThe device must operate on a 12V power supply.

11. Practical Constraints SafetyThe Radar Traffic Sensor must warn drivers of oncoming traffic. SustainabilityThe radar must require minimal maintenance.

12. Safety The Radar Traffic Sensing device is aimed towards traffic safety. We hope to prevent wrecks with this device by warning people of oncoming traffic in visual restricted area.

13. Sustainability The Radar Traffic Sensing device will be installed outside which means it will be exposed to heat, cold weather, water from rain, and other weather conditions.
