Surface-mounted traffic monitoring sensors that do not require substantial
disruption to traffic flow to install or maintain, and that do not substantially
degrade the physical integrity of the road. Pneumatic road-tube wedges and surface-mount
inductive blades detect wheel-spikes and/or inductive signatures in both fixed
and portable installations, single or multi-lane roadways, and provides accurate
vehicle speed, volume, occupancy, turning movement counts, weaving sections, classification,
re-identification, travel-time, origin and destination, lane-keeping variation,
speed-variation, angle-of-attack, and vehicle weight and load distribution. This
data is useful to infrastructure planners, traffic-flow modelers, to enhance the
safety of work-zone crews, law enforcement, and for real-time traffic operations, etc.
