Inductive Loop Signature

ILS 

Highlights

Single Loop Classification

ILS technology uses a single loop for vehicle classification, tracking, and speed estimation at per vehicle level.

Revolutionary

ILS technology generates a signature for each vehicle, compared to the bivalent signal from a traditional loop detector. 

Existing Infrastructure

ILS technology minimizes costs by utilizing existing single loop infrastructure.

The conventional traffic sensors typically provide volume, occupancy, vehicle presence and speed data. Vehicle reidentification is an emerging advanced sensor technology that aims to provide more data for the purposes of travel information, travel time estimation, and origin-destination (OD) estimation applications. According to the technologies applied, the vehicle reidentification systems can be categorized as:
