Comparison of Our Laser-Based System with Other Detection
Techniques
-
The system is mounted above the road and is relatively easy
to install.
-
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
high reliability.
-
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.
