IrisPRO Every Speed

The Every Speed Profiler (ESP) developed by ICC is a patented road profiling system designed to collect accurate and repeatable longitudinal profile and IRI at any vehicle speed, including low-speed, stop-and-go, and variable-speed conditions. Traditional inertial profiling systems are limited by a minimum speed threshold (around 12 mph), below which reliable profile and roughness data cannot be obtained.

The ESP eliminates this constraint by using dual line lasers in each wheel path in combination with a proprietary algorithm that enables accurate longitudinal profile measurements regardless of speed or vehicle motion. This includes accelerating, decelerating, or at a full stop, making the ESP uniquely suited for urban road networks, heavy traffic corridors, and short segments such as bridge decks.

The system captures height and motion data using a configuration of IMUs, lasers, and a distance measurement instrument (DMI), with all sensors interfaced through an onboard computer running ICC’s Drive™ software. The system records and computes roughness values such as the International Roughness Index (IRI), Profile Index (PI), or Ride Number (RN) in real-time and during post-processing. Certified to meet ASTM E950, AASHTO R56, AASHTO R57, and TxDOT specifications, the ESP produces data that is fully compatible with standard pavement engineering tools such as ProVAL and can be exported in formats including PPF, ERD, and PRO.

Field tests demonstrate the system’s performance is consistent across various speed profiles, with high-pass filtered profiles and IRI values showing negligible deviation between constant speed, variable speed, and full stop runs. This validates the system’s ability to deliver reliable, repeatable, and accurate results even in environments where traditional profilers fail, significantly enhancing the capabilities of agencies seeking year-round, all-condition roughness and profile data collection.

The ESP system revolutionizes the collection of road roughness, which is one of the most important metrics for road users.

ICC’s Mid-mount Adjustable Rail System (MARS) is designed for broad compatibility with a variety of trucks and SUVs, offering a flexible and efficient solution for vehicle-mounted profiling applications. Its compact, lightweight, and modular construction allows for quick and easy installation, while also simplifying international shipping and handling. The system supports adjustable mounting within a 68″ to 72″ wheel path range and offers a vertical height adjustment of up to 2.5″, ensuring precise sensor positioning. Integrated laser level adjustment further enhances alignment accuracy during setup.

Engineered for seamless integration, the MARS mounting system is fully compatible with ICC’s High-Speed Profiler (HSP) and our Every Speed Profiler (ESP) system. This compatibility allows users to implement advanced profiling technologies without requiring modifications to the mounting hardware and significantly reducing downtime.
