AASHTOWare Alliance Program

iENGINEERING exemplified the potential benefits of AASHTOWare Alliance Program with a new “Data Alliance” between AASHTOWare and iENGINEERING.

This alliance is centered around iENGINEERING’s Long Term Pavement Performance (LTPP) InfoPave Application Programming Interface (API), which integrates NASA’s Modern Era Retrospective analysis for Research and Applications (MERRA-2) climatic data with the AASHTOWare OpenAPI. The LTPP InfoPave API provides critical climatic data services to the AASHTOWare Pavement ME Design product, enabling state Departments of Transportation (DOTs) to access essential hourly climatic data for specific geolocations.

iENGINEERING has developed the Long-Term Pavement Performance (LTPP) InfoPave Application Programming Interface (API) for the Federal Highway Administration (FHWA) that provides access to National Aeronautics and Space Administration (NASA) Modern-Era Retrospective analysis for Research and Applications (MERRA-2) worldwide climatic data. NASA’s MERRA-2 climate data is the only available data source that provides users with access to processed versions of climatic data inputs.

The LTPP InfoPave API provides an authoritative source of climate data required for pavement design, analysis, and forecasting. By leveraging the API, users can access Hourly Climatic Data (HCD) for specific geolocations or entire counties. This API has been integrated with the AASHTOWare OpenAPI to provide climatic data services for AASHTOWare products. It allows for integration with AASHTOWare applications to access, interpret, and analyze MERRA-2 climatic data, providing HCD files from any location or device.

iENGINEERING is the sole provider of MERRA-2 climate data, hosted on the LTPP InfoPave website under contract with FHWA. The data have been collected globally from 1979 to the present at an hourly temporal resolution and a horizontal spatial resolution of 0.5 degrees latitude by 0.67 degrees longitude (approximately 50 by 65 km at mid-latitudes).

Climate data

Access Climatic Data

Integrate applications with MERRA-2 climatic data through the API. The AASHTOWare Open API integration allows full compatibility for integration with AASHTOWare applications.

Data Accuracy

Ensure Data Accuracy

The seamless flow of data from the LTPP InfoPave MERRA-2 database eliminates potential human errors and ensures access to accurate data records though AASHTOWare Open API.

Data range 1

Utilize Data Range

Leverage data for a specified time range, climatic attribute (temperature, precipitation, humidity, wind, or solar), and frequency (annual, monthly, daily, or hourly) for design, analytics, and forecasting.

Unlimited Use License

The LTPP InfoPave API is available at no cost to AASHTO and is integrated with the AASHTOWare Pavement ME product. Custom license is available for integration with AASHTO and State DOT products and services.
