<p>Surface-mounted traffic monitoring sensors (102, 104) 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 (402) wedges and surface-mount inductive blades (600) detect wheel-spikes and/or inductive signatures in both fixed and portable installations, single or multi-lane roadways (800), and provides accurate vehicle (200) 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.</p> |
