4A Values with AI-based Pavement Assessment

NEXCO Highway Solutions of America Inc. is a US subsidiary of NEXCO-Central, one of the world’s largest toll road operators based in Japan. As an experienced roadway operator, we understand the critical points in roadway management. It is always challenging for roadway operators to show the facts supporting budget plans. We need an innovative solution that provides reliable and precise data at affordable pricing.

Smart Pavement Management (SPM) is a NEXCO proprietary pavement assessment service leveraged by the latest AI. The 4A values with SPM—Accessible, Affordable, Accurate, Auxiliary—address the critical pain points in roadway management. As roadway operators, we pursue simple outputs so decision-makers can understand the facts at a glance while providing reliable and enough information on data-driven planning. SPM is an AI tool native to roadway operators.

We offer a 5-mile FREE trial run on your roadway system to show you the values. Please contact us today, and we will explain everything in detail.

AI Tech

Free Trial Run Project

Since SPM is a cutting-edge solution powered by the latest AI technology, a free trial run project would be necessary to better understand the benefits and values.

At the moment, more than 40 cities in North Texas and Oklahoma have commenced pilot projects.

Please contact us right now, to enjoy the opportunity.

What's New

At Work


SPM-PCI is NEXCO’s proprietary index system. Like Pavement Condition Index (PCI) using the ASTM 6433 standard, it is a numerical index between 0 and 100, which indicates the general condition of the surveyed pavement. SPM-PCI has a statistically significant correlation with PCI. 


SPM-IRI is a simplified readability index leveraged by machine-learning technology. Based on the bump data recorded while data collection, NEXCO's provides a roughness index.

Deterioration Prediction

Using a standard deterioration curve, SPM provides a prediction of future pavement conditions as an add-on feature of SPM-PCI.

Budget Simulation and Repair Planning

Based on SPM-PCI and the predictive feature, our algorithm automatically offers a simulation of different budget scenarios over the years. The algorithm suggests the optimal combination of repair segments based on our mathematical model. Also, the segments located in an area where many others require the same maintenance category gain higher weights in the calculation to make the suggested work plan efficient and realistic.  This entire process is designed to mimic the considerations of the engineers who conduct maintenance planning manually.
