Potential BenefitPotential BenefitSAVE LIVES!

Greatly reduce accident costs

•Accident resulting in a fatality - $2,723,000 per incident•Non-incapacitating crash - $48,000 per incident•Property damage only crash - $4,500 per incident

Economic costs for traffic crashes is $150 billion annually.

Example - Before-After Data for Rumble Strips in NY State•Prior - 565 ROR crashes, 360 injuries, & 14 fatalities

average per year.•After - 117 ROR crashes, 142 injuries, 2.5 fatalities average per year.•Total savings per year - $58,000,000

Proposed Solution RequirementsProposed Solution Requirements• Unique system to recognize road lines• Current technology• Find effective and reliable sensor• Must be at or next-to-real-time (NTRT)

1/200 second DADS computational requirement

• Non-intrusive• Economical• Software & Computer Component

• Develop Data Interpretive System (DIS)

• Identify Hardware - CPU• Develop Software• Suitable Audio, Visual, & Tactile

Alarms

Our ObjectivesOur Objectives

ScopeScope• Vehicle must travel 45 mph or greater for

system to engage• Idle when turn signal is on• Unable to detect obstructed lines

Hardware (1 of 4)Hardware (1 of 4) Sensors - Data Interpretive System (DIS)Sensors - Data Interpretive System (DIS)

• Infrared has large & robust output range• Sensors emit light & detect wavelengths of reflected light• Gray-scale infrared light range will be established

threshold• Reflected light wavelengths have corresponding voltages • Vehicle speed has no impact

10

Hardware (2 of 4)Hardware (2 of 4) Sensors - Data Interpretive System (DIS)Sensors - Data Interpretive System (DIS)

• 6 infrared sensors on a vehicle• 3 emitters and 3 detectors per sensor• Mounted on a small printed circuit board (PCB)

11

Hardware (3 of 4)Hardware (3 of 4) CPUCPU

• 32-bit RISC processor• Tailors itself to “smart”

automobile embedded solutions

• Able to perform at next-to-real-time (NTRT)

• Converts analog signal to associated voltage signal

• Compares to established threshold

• Sends control signal to that enables alarm system

12

Hardware (4 of 4)Hardware (4 of 4) CPUCPU

• To be active, speed must greater than 45 mph & turn signal off• Testing and simulation software - C++ software designed to

simulate machine code.• Will be used to check implementation of the software algorithms.

13

SoftwareSoftware•First layer provides sensor input and higher layer interface.

•Input layer has 3 modules; sensor, speedometer, turn signal.

•Middle layer is the processing module.

•Output layer sends control signal to 5-volt relay to activate alarms.

•Two input conditions controlled by the software to reduce equipment.
