I-10 Corridor Study Safety Analysis - New Mexico to Louisiana

Ardurra served as subconsultant to HNTB for the I-10 Corridor Study, analyzing current and future traffic and safety conditions across approximately 1,000 miles of Interstate 10 from the New Mexico to Louisiana border in Texas. The study examined planned transportation initiatives while identifying additional needs to improve safety, connectivity, and mobility along this critical transcontinental corridor.

The corridor study developed strategic classifications of four area types (rural, transition, urban, and dense urban), enabling detailed capacity and performance assessments with customized performance criteria that addressed unique regional characteristics. The analysis addressed complex variables, including significant growth areas, diverse population centers, varying job markets, and changes in traffic composition across the expansive corridor.

Key Corridor Study Components:

• Analyzed approximately 1,000 miles of I-10 from New Mexico to the Louisiana border, encompassing diverse geographic and demographic conditions

• Assessed over 30 major interchanges throughout Texas requiring individualized capacity and performance analysis

• Evaluated three major metropolitan areas, including El Paso, San Antonio, and Houston, with distinct traffic patterns and growth trajectories

• Addressed significant growth variability in corridor segments, creating unpredictable analysis conditions and future projections

• Integrated multiple data sources, creating specialized shapefiles and network files, enabling unique segmentation matching spatial and temporal requirements

• Developed short-, mid-, and long-term improvements addressing comprehensive corridor needs across rural, transition, urban, and dense urban areas

• Analyzed complex traffic composition variations, including population differences, employment patterns, and freight movement characteristics

The corridor study provides TxDOT with a strategic framework for long-term I-10 improvements that support economic development, safety enhancements, and mobility optimization across this vital transcontinental transportation artery serving diverse Texas communities and interstate commerce.
