Comparison of Our Laser-Based System with Other Detection
The system is mounted above the road and is relatively easy
The system is insensitive to ambient lighting conditions
due to the active lighting source (the laser).
It detects every passing object more than 1.5 foot tall in
all lighting conditions. No vehicles are missed, yielding 100% accuracy.
The laser and detector have no moving parts, giving the system
Not only does the detector produce local vehicle speed, vehicle
volume, and vehicle classifications, but it also allows highly deterministic
re-identification of vehicles between sites.
The system has very low power and communication bandwidth
requirements, allowing the development of a stand-alone detector untethered
from hard-wired infrastructure.
